What You Need to Know

• It's about logic, not grammar: The Production of Writing category (approximately 29–32% of the ACT English section) tests your ability to judge the logical flow, coherence, and focus of a passage, rather than punctuation or sentence structure.
• Context is king: You cannot answer these questions by reading a single sentence in isolation. You must read the surrounding sentences (and often the whole paragraph) to determine if information is relevant or placed correctly.
• Conciseness matters: If an addition provides redundant information or distracts from the main argument, the correct answer is usually to delete or omit it.
• Check the specific goal: For questions asking if the writer succeeded, the answer depends entirely on the specific goal stated in the prompt, not just the general topic of the essay.

Topic Development: Adding, Revising, and Deleting

This skill involves judging whether a piece of information belongs in the text. You will often be asked: "Should the writer add this sentence here?" or "The writer is considering deleting the underlined sentence. Should the writer do this?"

Determining Relevance

The primary rule for these questions is relevance. A sentence should only be added if it:

1. Supports the main idea of the paragraph.
2. Provides necessary definitions or context for a specific term.
3. Illustrates a point with a concrete example.

A sentence should be deleted if it:

1. Repeats information already stated elsewhere.
2. Drifts off-topic (tangential information).
3. Contradicts the tone or argument of the passage.

The "Yes/No" Strategy

Most answer choices are presented as pairs: two start with "Yes" and two start with "No."

1. Decide Yes or No first: Ignore the reasoning initially. Does the sentence belong? If it’s off-topic, it's a "No." If it defines a key term, it's a "Yes."
2. Check the reasoning: Once you've eliminated half the choices, compare the "because" statements. The correct reasoning must match the content of the text accurately.

Exam Focus

• Why it matters: These questions test your ability to maintain a coherent argument without getting distracted.
• Typical question patterns:
  • "The writer is considering adding the following sentence… Should the writer make this addition?"
  • "If the writer were to delete the underlined portion, the paragraph would primarily lose…"
• Common mistakes: Students often choose to add interesting facts even if they are irrelevant. Just because a fact is true (e.g., "The Eiffel Tower is in Paris") doesn't mean it belongs in a paragraph about baking croissants. If it doesn't serve the paragraph's specific function, kick it out.

Identifying Purpose and Evaluating Goals

These questions usually appear at the very end of a passage. They ask you to evaluate the passage as a whole against a hypothetical assignment or goal.

The "Writer's Goal" Question

The prompt will look like this: "Suppose the writer's goal had been to write an essay about [Topic X]. Does this essay fulfill that goal?"

To answer this:

1. Identify the specific goal: Read the prompt carefully. Is the goal to write a biography of a scientist, or to explain a specific scientific process?
2. Summarize the essay: Look at the title and the thesis statement. What did the essay actually do?
3. Compare: Does the summary match the specific goal?

Example: If the essay is about the life of Abraham Lincoln, but the prompt asks if the essay fulfills the goal of "explaining the political strategy behind the Emancipation Proclamation," the answer is No, because the essay is too broad (a biography), even though it is about Lincoln.

Exam Focus

• Why it matters: This tests high-level reading comprehension and the ability to distinguish between broad topics and specific rhetorical purposes.
• Typical question patterns:
  • "Suppose the writer's primary purpose had been to… Does this essay accomplish that purpose?"
• Common mistakes: Answering "Yes" just because the essay mentions the topic in the prompt. You must verify if the essay focuses on that topic or merely touches on it.

Logical Organization and Sequencing

ACT English tests your ability to order ideas logically. You may be asked to reorder sentences within a paragraph or reorder paragraphs within the whole passage.

Sentence Ordering

You will see a question like: "For the sake of the logic and coherence of this paragraph, Sentence 3 should be placed…"

Look for clues to connect sentences:

• Chronology: Look for dates, times, or steps in a process (first, then, finally).
• Pronouns: If Sentence 3 says "He picked up the ball," a previous sentence must introduce "He" and "a ball."
• Demonstratives: Words like "this," "that," "these," or "those" usually refer to something mentioned immediately before. If Sentence 4 starts with "These results were surprising," it must follow a sentence that lists results.

Paragraph Ordering

At the end of a passage, you might see: "The writer implies that Paragraph 4 should be placed…"

• Topic Sentences: Does the paragraph introduce a new idea? It might belong earlier.
• Concluding Sentences: Does it summarize the essay? It might belong at the end.
• Sandwich Method: Look at the end of the previous paragraph and the start of the next one. The moved paragraph must bridge the gap seamlessly.

Exam Focus

• Why it matters: Effective communication requires a linear, logical flow of information.
• Typical question patterns:
  • "[1] Sentence one. [2] Sentence two. [3] Sentence three…"
  • "Where is the most logical place for Sentence X?"
• Common mistakes: Ignoring the "bracketed numbers" [1] in the passage text. When you see numbers inside brackets at the start of sentences, immediately alert yourself that an ordering question is coming.

Cohesion: Transitions and Introductions/Conclusions

Cohesion refers to how well sentences "stick" together. Transitions are the glue.

Choosing the Right Transition

Transitions fall into three main logical categories. When you see a transition question, identify the relationship between the two sentences:

1. Continuation/Addition (Same direction): And, also, furthermore, in addition, moreover.
2. Contrast/Contradiction (Opposite direction): But, however, although, nevertheless, on the other hand.
3. Cause/Effect (Result): Therefore, consequently, thus, as a result, because.

Strategy: Read the sentence before and the sentence after the transition. If Sentence A says "It was raining" and Sentence B says "we went to the beach," you need a Contrast transition (e.g., "nevertheless"). If Sentence B says "we got wet," you need a Cause/Effect transition (e.g., "consequently").

Introductions and Conclusions

• Introductions: Must introduce the main topic. Avoid choices that are too specific or start "in the middle" of the action without context.
• Conclusions: Must provide closure. Avoid choices that introduce brand new information or unrelated topics. The best conclusion usually summarizes the main point or links back to the intro.

Exam Focus

• Why it matters: Without transitions, writing is choppy and relationships between ideas are unclear.
• Typical question patterns:
  • Underlined words like "However," "Therefore," or "Similarly."
  • "Which choice provides the most effective transition from the preceding paragraph?"
• Common mistakes:
  • Double transitions: Avoid using two transitions with the same meaning (e.g., "But however…").
  • The "OMIT" option: If the sentences flow logically without any transition word, the correct answer is often "OMIT the underlined portion" or the option with no transition word.

Quick Review Checklist

• Can you identify the specific goal in a "Writer's Goal" question prompt?
• Do you know the three main types of transitions (Continuation, Contrast, Cause/Effect)?
• Can you spot "pointer" words (this, that, these, those) to help order sentences?
• Can you determine if a detail is relevant enough to be added, or if it should be deleted for being off-topic?
• Do you know how to handle bracketed numbers [1] [2] [3] in a paragraph?
• Can you check the start and end of paragraphs to see if a transition effectively bridges them?

Final Exam Pitfalls

1. Falling for the "True but Irrelevant" Trap: Just because an added sentence is factually true doesn't mean it belongs in the essay. If it breaks the flow or changes the subject, delete it.
2. Ignoring the "No Change" Option: Statistically, "No Change" is correct about 25% of the time. If the logic holds and the grammar is correct, don't force a change just because it feels like you should.
3. Skimming the Prompt in Goal Questions: In "Suppose the writer's goal…" questions, if you miss one adjective in the prompt (e.g., "a humorous essay"), you might choose the wrong answer. Read every word of the target goal.
4. Redundant Transitions: Watch out for options like "recur again" or "joined together." If the meaning is already implied, adding a transition word makes it redundant. Simpler is often better.
5. Misinterpreting "Delete": When asked what is lost if a sentence is deleted, don't ask "Should we delete it?" Instead, simply describe what that specific sentence contains (e.g., "a specific example," "a definition").

What You Need to Know

• Production of Writing (an official ACT English reporting category) tests whether you can revise passages for purpose, focus, organization, unity, and cohesion—not just grammar.
• Many questions ask you to choose the best option (most effective, most logical, most relevant), so you must judge impact on the whole paragraph/passage, not just correctness.
• Your fastest path to points: identify the passage’s purpose and main point, then keep only details that support it in the best order with clear transitions.
• When stuck, prefer choices that are specific, concise, and consistent with the passage’s tone and point of view.

Topic Development and Relevance

Topic development is how well the passage builds and supports its main idea with specific, appropriate details. Relevance means every sentence earns its place by directly supporting the paragraph’s or passage’s focus.

What ACT typically tests

• Selecting details/examples that best support the point
• Removing off-topic or repetitive material
• Ensuring added information matches the paragraph’s focus and level of detail

How to decide if a detail is relevant

Ask:

• Does it support the main idea of this paragraph (not just the general topic)?
• Does it match the author’s purpose (inform, argue, narrate, describe, explain a process, etc.)?
• Is it at the right specificity level (not too vague, not overly technical for the passage)?
• Does it avoid derailing into a new subtopic?

Quick example (relevance)

Paragraph focus: “Why community gardens improve neighborhoods.”

• Relevant: a statistic about local participation (if the passage uses factual support), a brief example of reduced litter, a quote from a resident.
• Often irrelevant: a long history of gardening worldwide (too broad), a detailed tomato-growing guide (too specific and off-focus).

Exam Focus

• Why it matters: ACT uses these questions to measure whether you can revise writing for focus and support, a core part of effective composition.
• Typical question patterns:
  • “The writer is considering adding/deleting the following sentence. Should the writer do so?”
  • “Which choice best supports the main idea of the paragraph?”
  • “Which detail is most relevant to the preceding sentence/paragraph?”
• Common mistakes:
  • Keeping a sentence because it’s “interesting” even if it doesn’t support the point—choose support over trivia.
  • Picking the most detailed option even when it shifts focus—detail must be on-topic.
  • Ignoring paragraph purpose—evaluate relevance within the paragraph’s role in the passage.

Identifying the Purpose of a Text

Purpose is the author’s primary goal (to explain, persuade, describe, narrate, compare, evaluate, etc.) and sometimes a secondary goal (to entertain while informing).

How to identify purpose quickly

• Look at the opening and closing—they often reveal intent.
• Note the passage mode:
  • Narrative: events, characters, time order
  • Informative/explanatory: facts, definitions, processes
  • Persuasive/argument: claims + reasons, evaluative language
  • Descriptive: sensory detail, imagery
• Check what the passage emphasizes: telling a story vs. making a point vs. teaching information.

Real-world application

In school and work, you constantly adjust writing based on purpose—an email to request help (persuade) differs from a lab summary (inform).

Exam Focus

• Why it matters: Many revision decisions depend on purpose; ACT rewards choices aligned with the writer’s intent.
• Typical question patterns:
  • “The main purpose of this essay is to…”
  • “Which option best states the writer’s goal in this paragraph?”
  • “Which phrase best fits the tone/style of the passage?”
• Common mistakes:
  • Confusing topic with purpose (topic = what; purpose = why).
  • Choosing options that sound “formal” but don’t match the passage’s voice.
  • Ignoring the passage’s implied audience—purpose often depends on who’s being addressed.

Evaluating Whether a Text Achieves Its Goal

This skill is judging whether the passage’s content and structure actually accomplish the identified purpose—clearly, completely, and appropriately.

What “achieves its goal” usually means on ACT

• The main idea is clear early and reinforced throughout
• Support is sufficient (enough detail) and consistent (no contradictions)
• The writing is efficient: minimal redundancy, no tangents
• Tone and level of explanation match the intended audience

Mini-checklist for effectiveness

• Do you know the main point after the first paragraph?
• Does each paragraph have a job (example, explanation, counterpoint, next step)?
• Are there gaps where the reader would ask “Wait—why?” or “How?”

Exam Focus

• Why it matters: ACT often frames revision questions around improving clarity and effectiveness, not just correctness.
• Typical question patterns:
  • “Which revision best helps the essay accomplish its purpose?”
  • “Which sentence most effectively emphasizes the main point?”
  • “Which addition would provide the most helpful explanation?”
• Common mistakes:
  • Choosing a revision that is true but not useful for the goal.
  • Overlooking consistency—adding a detail that clashes with earlier statements.
  • Fixing a local sentence but harming overall flow—ACT rewards global improvement.

Adding, Revising, or Deleting Material

This is the core “editor” skill: deciding what to insert, change, or cut so the passage becomes clearer and more focused.

Common ACT tasks

• Add a sentence to clarify, provide an example, define a term, or connect ideas
• Revise wording for precision, tone, or consistency
• Delete redundancies, tangents, or obvious statements

Decision rules that score points

• Add when it answers a reader’s question (why/how/so what?) or supplies needed evidence.
• Delete when the sentence is off-topic, repetitive, or disrupts pacing.
• Revise when the original is vague (“things,” “stuff,” “a lot”) or inconsistent in tense/point of view/level of formality.

Example (delete vs. keep)

If a paragraph argues that a festival boosts local businesses, a sentence describing the author’s unrelated childhood memory is usually a delete—even if well-written.

Exam Focus

• Why it matters: These questions mirror real editing and are a major way ACT tests writing judgment.
• Typical question patterns:
  • “Should the writer add this sentence here?” (Yes/No + reason)
  • “If the writer removed the underlined sentence, the paragraph would primarily lose…”
  • “Which alternative best replaces the underlined portion?” (for clarity/precision)
• Common mistakes:
  • Picking “Yes, because it’s interesting”—reasons must connect to purpose/focus.
  • Deleting a sentence that provides a necessary bridge—watch for logic links.
  • Revising to be wordier—ACT often prefers clear and concise.

Logical Organization and Sequencing

Logical organization is arranging ideas so the reader can follow the writer’s thinking. Sequencing is the order of sentences/paragraphs (time order, cause-effect, general-to-specific, problem-solution, comparison).

Common organizational patterns

How to answer “order” questions fast

• Identify each sentence’s function (topic sentence, example, explanation, result, transition).
• Place definitions before they’re used.
• Put examples after the claim they support.
• Ensure cause comes before effect.

Exam Focus

• Why it matters: ACT frequently tests whether you can create a coherent structure—essential to effective writing.
• Typical question patterns:
  • “For the most logical order, sentence 4 should be placed…”
  • “Which sentence would best follow sentence X?”
  • “Which order of paragraphs best supports the passage’s purpose?”
• Common mistakes:
  • Ordering by what “sounds nice” instead of by logic (claim → support).
  • Missing reference words (“this,” “these,” “such”) that require an earlier antecedent.
  • Ignoring chronology cues in narrative/process passages.

Effective Introductions and Conclusions

An introduction sets context and states/implies the main idea; a conclusion reinforces the main point and provides closure (often by broadening, reflecting, or pointing forward).

What a strong ACT-style introduction does

• Establishes topic and purpose quickly
• Signals direction (main claim or controlling idea)
• Matches tone (informative vs. narrative vs. persuasive)

What a strong conclusion does

• Returns to the main idea without copying the introduction
• Avoids introducing a brand-new major point
• Leaves a clear final impression (implication, takeaway, next step)

Example cues

• Weak conclusion: adds a new statistic that changes the argument.
• Strong conclusion: synthesizes—“Overall, these changes show why…”

Exam Focus

• Why it matters: Beginnings and endings are high-impact, and ACT uses them to test purpose and coherence.
• Typical question patterns:
  • “Which opening sentence best introduces the paragraph/essay?”
  • “Which concluding sentence best closes the essay?”
  • “Which choice best sets up the information in the passage?”
• Common mistakes:
  • Choosing an intro that’s too broad (“Since the dawn of time…”)—ACT prefers direct, relevant openings.
  • Picking a conclusion that repeats word-for-word—aim for fresh synthesis.
  • Ending with a new topic—conclusions should wrap up, not expand into a new section.

Transitions Between Sentences and Paragraphs

Transitions are words/phrases/sentences that show relationships between ideas (contrast, addition, example, cause, time) and guide the reader through shifts.

High-frequency transition relationships

• Addition: “also,” “furthermore,” “in addition”
• Contrast: “however,” “nevertheless,” “on the other hand”
• Cause/effect: “therefore,” “as a result,” “because”
• Example: “for instance,” “specifically”
• Time/sequence: “then,” “meanwhile,” “afterward”

Strategy for choosing the best transition

1. Identify the relationship between the two sentences/paragraphs.
2. Eliminate transitions that signal the wrong relationship (contrast vs. cause is a common trap).
3. Prefer the most precise connector (e.g., “for example” is better than “also” when introducing evidence).

Exam Focus

• Why it matters: Transitions are a main tool for cohesion; ACT tests whether you can make logic explicit.
• Typical question patterns:
  • “Which transition best connects the ideas in these sentences?”
  • “Which phrase best links this paragraph to the previous one?”
  • “Which word/phrase best indicates the relationship?”
• Common mistakes:
  • Choosing a transition based on tone rather than logic—match the relationship.
  • Overusing “however” when the idea is actually addition or example.
  • Ignoring paragraph-level transitions—ACT also tests between paragraphs, not just within.

Unity and Cohesion

Unity means a paragraph/passage sticks to one controlling idea. Cohesion means the parts connect smoothly through consistent references, clear pronouns, and logical flow.

How unity is built

• A clear topic sentence (or controlling idea)
• Supporting sentences that all relate to that idea
• No major digressions

How cohesion is built

• Clear referents: pronouns (“it,” “they,” “this”) clearly point to a specific noun
• Repetition of key terms (not excessive) and consistent naming
• Consistent tense, point of view, and tone

Example (cohesion issue)

Problem: “The committee launched the program. This improved attendance.”

• Question to ask: what does “This” refer to—launching? the program? a specific change?
• Better: “The program’s new schedule improved attendance.”

Exam Focus

• Why it matters: Unity and cohesion are central to the ACT’s “big picture” editing—making writing easy to follow.
• Typical question patterns:
  • “Which sentence best maintains the unity of the paragraph?”
  • “Which revision improves the cohesion of the passage?”
  • “To make this paragraph most coherent, the writer should…”
• Common mistakes:
  • Leaving in a sentence that shares a keyword but not the paragraph’s point.
  • Missing unclear pronouns or “this/that” references.
  • Creating inconsistent perspective (switching between “you,” “we,” and “they”).

Quick Review Checklist

• Can you identify a passage’s purpose (inform, persuade, narrate, etc.) using openings/closings and tone clues?
• Can you decide whether a sentence is relevant to a paragraph’s controlling idea?
• Can you explain why adding a detail would help achieve the author’s goal (not just “add information”)?
• Can you choose the most logical sentence placement by labeling each sentence’s function (claim, example, explanation)?
• Can you recognize the best organizational pattern (chronological, cause-effect, general-to-specific) for the passage?
• Can you select an introduction that sets up the main idea without being overly broad?
• Can you select a conclusion that synthesizes rather than introducing a new major point?
• Can you pick transitions by identifying the exact relationship (contrast vs. cause vs. example)?
• Can you revise to improve cohesion by fixing unclear pronouns and inconsistent point of view?

Final Exam Pitfalls

1. Choosing options that are “true” but not useful — pick the choice that best supports the paragraph’s purpose and focus.
2. Misreading transition logic (e.g., using contrast when the idea is cause/effect) — first name the relationship, then choose the connector.
3. Keeping tangents because they sound good — ACT rewards unity; delete or avoid sentences that don’t do the paragraph’s job.
4. Placing examples before the claim they support — keep a clear sequence: claim → evidence/example → explanation.
5. Endings that introduce new ideas — conclusions should provide closure and reinforce the main takeaway.

What You Need to Know

• Production of Writing accounts for roughly 29–32% of your ACT English score (about 20–23 of the 75 questions). These questions ask you to improve the development, organization, and overall effectiveness of a passage — not just fix grammar.
• Unlike Usage/Mechanics questions that test rules, Production of Writing questions require you to read strategically: understand the writer's purpose, evaluate whether content belongs, and judge the best placement of ideas.
• The most reliable strategy is to identify the writer's goal first, then evaluate every answer choice against that goal. If a choice doesn't serve the passage's purpose, it's wrong — no matter how well-written it sounds.
• Transitions, introductions, conclusions, and sentence placement questions all hinge on logical relationships between ideas. Always re-read surrounding sentences before answering.

Topic Development and Relevance

Topic development refers to how well a passage supports, elaborates on, and stays focused on its central idea. On the ACT, you'll be asked whether specific details strengthen a paragraph, whether a sentence is relevant to the topic at hand, and whether additional information is needed.

Key principles:

• Every sentence in a paragraph should relate to the topic sentence or the paragraph's main idea.
• Relevant details provide evidence, examples, explanations, or descriptions that advance the writer's point.
• Irrelevant details — even if interesting or factually true — should be cut if they distract from the paragraph's focus.

How to Evaluate Relevance

Ask yourself: Does this sentence help the reader understand the paragraph's main point better? If it introduces a tangent, a loosely related fact, or an off-topic personal opinion, it weakens development.

Exam Focus

• Why it matters: These questions test your ability to think like an editor — a core skill the ACT values across nearly a third of the English section.
• Typical question patterns:
  • "Which choice most effectively supports the point made in the previous sentence?"
  • "Given that all the choices are true, which one provides the most relevant information at this point in the essay?"
  • "The writer wants to provide a specific example that illustrates the claim made earlier. Which choice best accomplishes this goal?"
• Common mistakes:
  • Choosing an answer because it sounds impressive or contains interesting facts — relevance to the passage always trumps general interest.
  • Ignoring the specific focus of the paragraph and instead matching the broad topic of the entire essay.

Identifying the Purpose of a Text

Many ACT English questions ask you to determine what a passage, paragraph, or sentence is trying to accomplish. Purpose can be broadly categorized as:

You won't be asked to label the purpose directly. Instead, purpose is embedded in questions like "The writer wants to convey a sense of excitement" or "The writer's goal is to provide a brief overview of…"

Exam Focus

• Why it matters: Identifying purpose is foundational — almost every Production of Writing question implicitly requires you to understand what the writer is trying to do.
• Typical question patterns:
  • "Which choice best conveys the narrator's sense of [emotion/tone]?"
  • Questions that begin with "Suppose the writer's goal is to…" followed by "Would this essay accomplish that goal?"
• Common mistakes:
  • Confusing the topic of the essay with the purpose (a passage about recycling could inform, persuade, or narrate — the topic alone doesn't tell you).
  • Selecting an answer that matches your personal preference rather than the writer's established tone and intent.

Evaluating Whether a Text Achieves Its Goal

These questions typically appear at the end of a passage. They present a hypothetical goal — e.g., "Suppose the writer intended to write an essay that details the history of jazz in New Orleans" — and ask whether the essay fulfills it.

Your approach:

1. Restate the goal in your own words.
2. Compare the goal to what the essay actually covers.
3. Choose Yes or No, then pick the reason that accurately explains why.

Critical tip: The Yes/No answer AND the reasoning must both be correct. A right Yes with a wrong reason is still wrong.

Exam Focus

• Why it matters: This question type appears at least once per test, usually as the last question on a passage.
• Typical question patterns:
  • "Suppose the writer's purpose is to [goal]. Does the essay accomplish this purpose?" with four options (two Yes with reasons, two No with reasons).
• Common mistakes:
  • Choosing the correct Yes/No but pairing it with an inaccurate justification — always verify that the reasoning matches the actual content of the essay.
  • Overthinking scope: if the goal says "brief overview" and the essay gives a brief overview, that's a match, even if you feel the essay could have gone deeper.

Adding, Revising, or Deleting Material

These questions ask you to decide whether a sentence or phrase should be added, revised, or deleted — and why.

Adding Material

• A sentence should be added if it fills a gap in logic, provides a needed example, or strengthens a transition.
• It should NOT be added if it's redundant, off-topic, or contradicts the passage's tone.

Deleting Material

• A sentence should be deleted if it's irrelevant, redundant, or undermines the paragraph's focus.
• It should be kept if removing it would create a logical gap.

Choosing the Right Reason

The ACT always pairs the add/delete decision with a justification. You must evaluate both. Common correct reasons include: "it blurs the focus," "it provides a relevant example," or "it repeats information already stated."

Exam Focus

• Why it matters: Add/revise/delete questions are among the most frequent Production of Writing question types — expect 4–6 per test.
• Typical question patterns:
  • "The writer is considering deleting the preceding sentence. Should the sentence be kept or deleted?"
  • "The writer wants to add the following sentence. Should the writer make this addition here?"
• Common mistakes:
  • Keeping a sentence just because it contains true or interesting information — truth is not the same as relevance.
  • Forgetting to read the full paragraph context; a sentence that seems fine in isolation may be redundant given what's already stated.

Logical Organization and Sequencing

These questions ask you to reorder sentences within a paragraph or reorder paragraphs within the essay so that the passage flows logically.

Strategies for Sentence Placement

• Look for pronoun references: a sentence using "this discovery" must come after the discovery is introduced.
• Look for chronological clues: dates, time words ("later," "before that," "eventually").
• Look for logical cause-and-effect: the cause must precede the effect.
• Look for transitions: words like "however," "in addition," or "as a result" signal what must come before.

Paragraph Reordering

• The introduction paragraph and conclusion paragraph are usually identifiable — anchor them first.
• Trace the logical progression of ideas between body paragraphs.

Exam Focus

• Why it matters: Expect 2–4 ordering questions per test; they can be time-consuming if you don't have a strategy.
• Typical question patterns:
  • "For the sake of the logic and coherence of this paragraph, Sentence 3 should be placed: (A) where it is now, (B) before Sentence 1, (C) after Sentence 4…"
  • "Which of the following sequences of paragraphs makes the essay most logical?"
• Common mistakes:
  • Not re-reading the full paragraph with the sentence in the proposed new position — always mentally test placement.
  • Ignoring transition words that anchor a sentence to a specific location.

Effective Introductions and Conclusions

Introductions should establish the topic, set the tone, and engage the reader. Conclusions should provide closure — summarizing, reflecting, or reinforcing the main idea without introducing entirely new information.

On the ACT, you may be asked to choose the best opening or closing sentence for a paragraph or essay.

What Makes a Strong Introduction

• Clearly signals what the passage will discuss
• Matches the tone of the rest of the essay
• Is specific enough to guide the reader but not so detailed it belongs in the body

What Makes a Strong Conclusion

• Echoes or ties back to the main idea
• Doesn't introduce a brand-new topic
• Provides a sense of finality or reflection

Exam Focus

• Why it matters: Introduction/conclusion questions test your big-picture understanding of the passage.
• Typical question patterns:
  • "Which choice most effectively opens this essay?"
  • "Given that all the choices are true, which one most effectively concludes the essay by summarizing its main idea?"
• Common mistakes:
  • Choosing a conclusion that introduces new evidence or a tangent rather than wrapping up existing ideas.
  • Selecting an introduction that is too narrow (fitting only one paragraph) or too broad (not matching the essay's specific scope).

Transitions Between Sentences and Paragraphs

Transitions are words, phrases, or sentences that connect ideas and signal the relationship between them. The ACT frequently tests whether you can choose the correct transitional word or sentence.

Strategy

1. Read the sentence before and after the transition.
2. Determine the logical relationship (contrast? addition? cause?).
3. Choose the transition that accurately reflects that relationship.

Exam Focus

• Why it matters: Transition questions appear frequently — roughly 3–5 per test — and are quick points once you master the skill.
• Typical question patterns:
  • "Which choice most effectively signals the relationship between this sentence and the previous one?"
  • A transition word is underlined, and you pick the best replacement from four options.
• Common mistakes:
  • Using "however" when the second sentence actually continues or builds on the first (no contrast exists).
  • Choosing "therefore" when no cause-and-effect relationship is present — always verify the logical connection.

Unity and Cohesion

Unity means every sentence in a paragraph serves a single main idea. Cohesion means sentences connect smoothly so the reader can follow the writer's line of thought without confusion.

A paragraph has unity when:

• It has a clear topic sentence (often the first sentence)
• All supporting sentences relate directly to that topic
• No sentence introduces an unrelated subtopic

A paragraph has cohesion when:

• Ideas progress logically from one sentence to the next
• Transitions link ideas clearly
• Pronouns and repeated key terms create continuity

Unity and cohesion underlie many Production of Writing questions — they're often tested indirectly through add/delete, ordering, and transition questions.

Exam Focus

• Why it matters: Unity and cohesion are the conceptual backbone of nearly every Production of Writing question. Understanding these principles helps you answer many question types faster.
• Typical question patterns:
  • Tested indirectly: questions about deleting irrelevant sentences test unity; questions about transitions test cohesion.
  • "For the sake of the unity and coherence of this paragraph…"
• Common mistakes:
  • Confusing unity (on-topic focus) with cohesion (smooth flow) — a paragraph can be unified but choppy, or cohesive but off-topic.
  • Assuming a well-written sentence automatically belongs — if it doesn't serve the paragraph's main idea, it breaks unity regardless of quality.

Quick Review Checklist

• Can you identify the main purpose of a passage (inform, persuade, narrate, reflect)?
• Can you determine whether a specific sentence is relevant to a paragraph's focus?
• Do you know how to evaluate whether an essay achieves a stated goal — and select the correct reason?
• Can you decide whether material should be added, kept, or deleted based on relevance and redundancy?
• Can you reorder sentences logically by using pronouns, transitions, and chronological clues?
• Do you know the difference between an effective introduction (sets up the topic) and an effective conclusion (provides closure without new material)?
• Can you choose the correct transition word by identifying the relationship between two sentences?
• Do you understand the difference between unity (single focus) and cohesion (smooth connections)?
• Can you spot redundant information and recognize when a detail — even a true one — doesn't belong?

Final Exam Pitfalls

1. Choosing "sounds good" over "fits the purpose." A beautifully worded sentence is wrong if it doesn't serve the passage's goal. Always evaluate function before style.

2. Ignoring the reason in Yes/No questions. On "Does the essay accomplish its goal?" questions, both the Yes/No answer and the justification must be correct. Read all four options carefully.

3. Treating all true statements as relevant. The ACT loves to offer answer choices that are factually accurate but off-topic. Your job is to pick what's relevant, not what's true.

4. Rushing through ordering questions. Sentence-placement questions require you to re-read the paragraph with the sentence in the new position. Skipping this step leads to careless errors.

5. Defaulting to "DELETE" or "KEEP" without checking. Students sometimes develop a bias toward one option. Always evaluate the specific context — there's no universal rule for whether to keep or delete.

6. Misidentifying the transitional relationship. Don't assume contrast just because two sentences discuss different aspects of the same topic. Read both sentences and name the relationship before choosing a transition word.
