What You Need to Know

• Knowledge of Language questions make up approximately 15–20% of the ACT English test.

• These questions do not test grammar rules (like comma usage or subject-verb agreement) but rather style, tone, clarity, and concision.

• The correct answer is almost always the most concise option that preserves the original meaning and tone.

• You must identify the author's voice (formal, casual, scientific) and ensure all word choices match that context.

Precision and Clarity in Word Choice

This topic tests your ability to select the exact word that fits the context of the sentence. It requires understanding nuances in meaning and recognizing standard English idioms.

Diction and Nuance

Diction refers to specific word choice. The ACT often presents options that are grammatically functional but logically or contextually incorrect. You must choose the word that makes the most sense.

• Similar-sounding words: Be careful with words that look or sound alike but have different meanings.

  • Example: Allude (to reference) vs. Elude (to escape).

  • Example: Eminent (famous/respected) vs. Imminent (about to happen).

• Contextual Fit: A word might be a synonym in a dictionary but wrong in the specific sentence.

  • Poor: The scientist cooked up a new theory.

  • Better: The scientist formulated a new theory.

Idiomatic Expressions

English idioms often dictate that specific prepositions follow specific verbs or adjectives. These are fixed phrases.

• Common Idiom Errors:

  • Incorrect: He is capable to run a marathon.

  • Correct: He is capable of running a marathon.

  • Incorrect: She has an interest to science.

  • Correct: She has an interest in science.

Exam Focus

• Why it matters: Misusing a word can change the factual meaning of a passage or make the writing confusing. The ACT prioritizes clear communication.

• Typical question patterns:

  • A word is underlined, and the options offer three synonyms with slightly different connotations (e.g., happy, ecstatic, content, pleased).

  • An idiomatic phrase is underlined (e.g., abide by vs. abide with).

• Common mistakes: Choosing a "fancy" or high-vocabulary word just because it sounds sophisticated. Often, the simpler word is the precise one.

Concision and Eliminating Redundancy

The "Concision" principle is one of the most reliable strategies on the ACT English section. The test prefers the shortest, most direct way to state an idea, provided it does not lose important information.

The "Shortest is Best" Heuristic

If you see three or four options that are grammatically correct and express the same essential meaning, the shortest option is usually the correct answer. This is not a strict rule, but a very strong tendency.

• Wordy: The reason why he left was because he was tired.

• Concise: He left because he was tired.

Redundancy

Redundancy occurs when a sentence repeats a concept unnecessarily. The ACT frequently pairs a word with a modifier that implies the same definition.

Exam Focus

• Why it matters: Effective writing avoids waste. Redundancy clutters the text and lowers the quality of the prose.

• Typical question patterns:

  • An underlined portion contains a definition immediately followed by the word itself (e.g., "the joyful happy boy").

  • One option is the word "OMIT the underlined portion." If deleting the text removes redundancy without creating a grammatical error, this is often the right answer.

• Common mistakes: Thinking that longer answers sound more "academic" or detailed. On the ACT, extra words are usually wrong unless they add new, necessary information.

Consistency in Style and Tone

Passages on the ACT have a specific voice. Some are formal historical narratives; others are personal memoirs or scientific reports. You must maintain consistency throughout the passage.

Identifying the Tone

Read the first paragraph carefully to establish the baseline tone.

• Formal/Academic: Uses complex sentence structures, precise vocabulary, and objective language. (e.g., "The data suggests a correlation…")

• Informal/Conversational: Uses first-person pronouns, contractions, and simpler vocabulary. (e.g., "I couldn't believe my luck…")

Avoiding Tone Shifts

The error occurs when a sentence abruptly switches registers.

Example of a Tone Shift:

Here, "freaked out" is too slang-heavy for a sentence about the Supreme Court. A better choice would be "expressed concern" or "vehemently objected."

Exam Focus

• Why it matters: Good writing requires a unified voice. Jarring shifts distract the reader.

• Typical question patterns:

  • The question asks which choice best fits the "tone and style" of the passage.

  • Options range from slang ("super cool") to archaic ("hath given") to standard English ("very interesting").

• Common mistakes: Choosing an option that is grammatically correct but stylistically jarring (e.g., using slang in a science passage).

Rhetorical Effectiveness

These questions ask you to act as an editor. You aren't just looking for what is correct; you are looking for what is best for a specific purpose stated in the prompt.

Satisfying the Prompt

Unlike grammar questions, which you can often answer just by reading the sentence, rhetorical questions usually have a prompt box appearing before the options. You must read the specific goal in the prompt.

Example Prompt: "Which choice best emphasizes the speed of the vehicle?"

• Option A: The car moved down the highway.

• Option B: The car raced down the highway.

• Option C: The car traveled down the highway.

• Option D: The car went down the highway.

While all options are grammatically valid, only Option B (raced) emphasizes speed as requested.

Specificity vs. Generalization

Generally, the ACT prefers specific, vivid language over vague generalizations, provided the specific details fit the context.

• Vague: The stuff on the table was messy.

• Specific: The stacks of unfiled papers and overflowed coffee cups cluttered the table.

Exam Focus

• Why it matters: Writing is about communication goals. This tests if you can follow instructions to achieve a specific descriptive outcome.

• Typical question patterns:

  • "Which choice most effectively sets up the information in the next sentence?"

  • "Which choice provides the most specific description of the landscape?"

• Common mistakes: Ignoring the prompt and picking the answer that "sounds best" or is shortest. If the prompt asks for a description of sound, do not pick the answer that describes color, even if it is beautifully written.

Quick Review Checklist

• Can you identify redundancy? (e.g., recognizing that "advance forward" is repetitive because advance implies forward motion.)

• Do you check the prompt? (If a question stem asks for a specific emphasis, do you ignore the "shortest is best" rule to satisfy that specific goal?)

• Can you spot tone shifts? (Can you tell if a word is too casual for a formal passage or too stiff for a narrative?)

• Do you know your idioms? (Are you comfortable with pairing prepositions like consistent with, protest against, or insight into?)

• Can you distinguish similar words? (Do you know the difference between then/than, effect/affect, and principle/principal?)

Final Exam Pitfalls

1. Ignoring the Question Stem: Students often skip the bold text asking for a specific goal (e.g., "emphasize the character's frustration") and just pick the shortest answer. Correction: Always read the question stem first. If it has a specific goal, the "concision rule" is secondary to answering the prompt.

2. Over-correcting for "Sophistication": Students often pick the longest, most complex word because it looks smart (e.g., choosing "utilize" over "use" when "use" is perfectly fine). Correction: Simple and clear is usually better than complex and obscure.

3. Missing "OMIT" Options: When "OMIT the underlined portion" is an option, students are afraid to pick it, thinking something must be there. Correction: Test the sentence without the underlined part. If it makes sense and is grammatically complete, OMIT is very likely the correct answer.

4. Redundancy Blindness: Students gloss over phrases like "reason because" or "quickly rushed" because they hear them in spoken English. Correction: Be hyper-critical of any word that repeats a meaning already present in the sentence.

What You Need to Know

• Knowledge of Language questions test whether a revision makes writing clearer, more precise, more consistent, and more effective—not whether it “sounds fancy.”

• When choices all seem grammatical, pick the option that best matches the passage’s purpose, tone, and logic while staying concise.

• Prefer specific, unambiguous wording and avoid redundancy—ACT rewards the cleanest sentence that preserves the intended meaning.

• Keep style and tone consistent across a passage; don’t let a single sentence switch formality, point of view, or level of certainty.

Curriculum anchor (official ACT scope): ACT’s official English test reporting categories include Conventions of Standard English, Production of Writing, and Knowledge of Language (effective language use—word choice, style, tone, clarity). ACT also publishes that Knowledge of Language is a smaller share of English than the other two categories (commonly presented in ACT prep materials as roughly about a dozen questions on a 75-question English test, expressed as an approximate percentage range).

Precision and Clarity in Word Choice

Precision means choosing the most exact word for the idea; clarity means the reader can understand the meaning quickly with minimal rereading.

What ACT is testing

On Knowledge of Language items, ACT often gives options that are all “acceptable” but differ in specificity and ambiguity.

Key targets:

• Specific verbs over vague verbs (e.g., “indicates,” “demonstrates,” “argues” instead of “says”).

• Concrete nouns over broad nouns when the context supports it (e.g., “permit,” “blueprint,” “budget” instead of “document”).

• Avoiding ambiguous pronouns (this, that, it, they) when the referent could be unclear.

• Correct connotation—a word’s emotional/associative meaning must fit the tone (e.g., “childlike” vs. “childish”).

Quick decision rules

• If two choices mean almost the same thing, choose the one that is more exact and fits the passage’s voice.

• If a word could be interpreted multiple ways, prefer the option that locks in the intended meaning.

• Don’t “upgrade” vocabulary if it changes meaning or tone—ACT prefers accuracy over sophistication.

Examples (typical ACT style)

Example 1: Specificity

• Original idea: The scientist’s results show the new material is stronger.

• Better: “The scientist’s results demonstrate that the new material is stronger.”
  Why: “Demonstrate” is more precise than “show” in a formal/explanatory context.

Example 2: Pronoun clarity

• Risky: “When Maria spoke to Elena about the award, she was thrilled.”

• Clearer: “When Maria spoke to Elena about the award, Elena was thrilled.”
  Why: Removes ambiguity about who is thrilled.

Useful comparison table

Exam Focus

• Why it matters: When grammar isn’t the issue, ACT differentiates top scores by testing whether you can revise for exact meaning and readability.

• Typical question patterns:

  • “Which choice best conveys the writer’s meaning?” (options vary by nuance)

  • Replacing a vague word with a more precise one

  • Fixing an unclear pronoun/reference

• Common mistakes:

  • Choosing the “most advanced” word even if it shifts meaning—pick the word that matches context.

  • Ignoring connotation—a negative/positive shade can break the passage’s tone.

  • Leaving an ambiguous pronoun because it’s grammatical—ACT cares about reader clarity.

Concision and Eliminating Redundancy

Concision means expressing the same idea in fewer, cleaner words without losing meaning. Knowledge of Language questions often reward the shortest option that still communicates the full idea.

What ACT is testing

You’re asked to cut:

• Redundancy (repeating the same idea)

• Wordiness (extra words that add no meaning)

• Inflated phrases that can be one word

Common redundancy patterns:

• “each and every” → “each”

• “basic fundamentals” → “fundamentals”

• “in order to” → “to”

• “the reason is because” → “because”

• “future plans” → “plans” (usually)

Concision without losing meaning

The ACT trap is that the shortest choice is not always right if it:

• removes a necessary detail, or

• creates a meaning change (too strong/too weak), or

• makes the sentence illogical.

Examples (with reasoning)

Example 1: Cutting filler

• Wordy: “The committee came to the conclusion that the proposal should be revised.”

• Concise: “The committee concluded that the proposal should be revised.”

Example 2: Removing doubled meaning

• Redundant: “The mural was completely finished after two months.”

• Better: “The mural was finished after two months.”
  (“Finished” already implies complete in most contexts.)

High-yield edit moves

• Replace “there is/there are” openings when they add clutter.

  • “There are many researchers who argue…” → “Many researchers argue…”

• Prefer active, direct phrasing if it’s clearer and not a tone mismatch.

• Delete “that” when it’s optional and doesn’t reduce clarity.

Exam Focus

• Why it matters: ACT emphasizes efficient communication; concise writing improves clarity and is frequently tested in revision choices.

• Typical question patterns:

  • “Which choice results in the most concise sentence?”

  • Delete/keep an underlined portion (“If the writer were to delete… would the paragraph lose important information?”)

  • Choosing between a short verb and a long phrase (“utilize” vs. “use,” “due to the fact that” vs. “because”)

• Common mistakes:

  • Always picking the shortest option—even when it drops a key idea.

  • Cutting words that maintain logical relationships (e.g., removing “however,” “therefore” when contrast/causation matters).

  • Deleting clarifying repetition that is actually needed (rare, but possible in complex sentences).

Consistency in Style and Tone

Style is how the writing sounds (formal/informal, technical/general, energetic/neutral). Tone is the writer’s attitude toward the subject (enthusiastic, critical, reflective, humorous). Knowledge of Language questions often test whether a sentence matches the passage’s established voice.

Consistency targets ACT loves

• Formality level: academic vs. casual

  • Mismatch example: “Researchers conducted a longitudinal study, and the results were pretty awesome.”

• Point of view: don’t shift between you / we / one / they unless the passage intentionally does.

• Verb tense: keep a stable timeline unless the meaning requires a shift.

• Level of certainty: “might suggest” vs. “proves” (don’t overstate).

• Register and jargon: don’t introduce technical terms if the passage is general-audience (unless the passage already uses them and defines them).

How to “read the room” fast

Before answering, scan nearby sentences for:

• the passage’s audience (students? general readers? specialists?)

• the passage’s purpose (inform, narrate, persuade, describe)

• the narrator’s voice (objective reporter vs. personal storyteller)

Example edits

Example 1: Formality alignment

• Off-tone: “The city implemented new zoning rules to address runoff, which was a big deal for residents.”

• Better (more formal): “…which was significant for residents.”

Example 2: Consistent point of view

• Shift: “Drivers should check tire pressure regularly. You can also rotate tires every 5,000 miles.”

• Consistent: “Drivers should check tire pressure regularly. They can also rotate tires every 5,000 miles.”
  (Unless the passage is written as direct advice to “you,” in which case keep “you” consistently.)

Exam Focus

• Why it matters: ACT rewards revisions that make the passage sound like one coherent piece, not a patchwork of mixed voices.

• Typical question patterns:

  • Selecting the option that best matches the passage’s overall tone

  • Fixing a sudden shift in point of view or verb tense

  • Choosing words that match the passage’s formality level

• Common mistakes:

  • Choosing a casual phrase because it sounds “natural,” even when the passage is formal.

  • Missing subtle POV shifts (especially one ↔ you ↔ we).

  • Overstating claims (“proves,” “always,” “never”) when the passage is cautious.

Rhetorical Effectiveness

Rhetorical effectiveness means choosing language that best achieves the writer’s goal—emphasis, logic, transitions, and persuasive impact—while staying clear and consistent.

What ACT is testing

These questions ask whether a change makes the writing:

• More logically connected (cause/effect, contrast, sequence)

• More emphatic or vivid (when appropriate)

• More coherent across sentences and paragraphs

High-yield skills

1) Choose the right transition

Match the transition to the relationship:

• Addition: moreover, furthermore

• Contrast: however, nevertheless, on the other hand

• Cause/effect: therefore, thus, consequently

• Example: for instance, for example

• Time/sequence: then, next, afterward

Mini-check: Ask yourself: “Is the next sentence adding, contrasting, explaining, or resulting?”

2) Emphasis and sentence structure

Sometimes the best choice places key information:

• Earlier (for punch/clarity), or

• at the end (for a strong finish),
  without creating wordiness.

3) Maintain appropriate level of persuasion

In argumentative passages, effective choices:

• avoid emotional overreach,

• use accurate qualifiers (often/sometimes/likely),

• sound credible for the context.

Examples

Example 1: Transition logic

• Sentence A: “The trail is steep and rocky.”

• Sentence B: “The park recommends sturdy footwear.”
  Best connector: “Therefore” (recommendation follows from conditions).
  Wrong-feeling connector: “However” (no contrast).

Example 2: Strength of claim

• Too absolute: “This policy eliminates traffic congestion.”

• More credible: “This policy reduces traffic congestion.”
  (Unless the passage provides proof of elimination—which is rare.)

Exam Focus

• Why it matters: Many ACT English items measure whether you understand how sentences work together to achieve a purpose—clarity plus persuasive/cohesive impact.

• Typical question patterns:

  • Choosing the best transition word/phrase

  • Picking wording that best supports the writer’s purpose (informative vs. persuasive vs. narrative)

  • Revising to improve emphasis or logical flow

• Common mistakes:

  • Choosing transitions by “vibe” instead of identifying the exact relationship.

  • Preferring dramatic wording that weakens credibility.

  • Missing that the passage is neutral/informative—overly persuasive language can be off-tone.

Quick Review Checklist

• Can you choose the most precise word when options differ only slightly in meaning?

• Can you spot and fix an ambiguous pronoun reference?

• Can you identify and delete redundant words or repeated ideas without changing meaning?

• Can you pick the most concise revision that still keeps necessary details?

• Do you know how to maintain consistent tone (formal vs. informal) across a passage?

• Can you keep point of view and verb tense consistent unless a shift is logically required?

• Can you match a transition to the correct logical relationship (contrast, cause, example, sequence)?

• Can you choose wording that strengthens credibility (avoiding overstatements) when the passage is academic or informational?

Final Exam Pitfalls

1. Picking “fancier” vocabulary that slightly changes meaning → Choose the word that matches the author’s exact claim and context, even if it’s simpler.

2. Auto-picking the shortest answer → Concision wins only when the meaning is fully preserved and clarity doesn’t drop.

3. Ignoring passage voice (sudden slang/formality shift) → Use surrounding sentences to match the established style and audience.

4. Transition roulette → Determine whether the next idea adds, contrasts, explains, or results; then choose the connector.

5. Overstating claims in informational passages → Prefer measured, accurate verbs (suggests/indicates/reduces) unless the passage clearly supports a stronger claim.

What You Need to Know

• Knowledge of Language questions make up roughly 12–15% of the ACT English test (about 8–12 of the 75 questions). They test your ability to refine writing—not fix grammar errors, but make sentences sharper, clearer, and more effective.

• The core skill is choosing the best version of a sentence—the one that is most precise, concise, stylistically consistent, and rhetorically effective.

• Unlike Usage/Mechanics questions, Knowledge of Language questions rarely have a single "rule" you can point to. Instead, you must judge which answer choice sounds best in context.

• When in doubt, shorter is usually better on the ACT—unless the shorter option sacrifices meaning or clarity.

Precision and Clarity in Word Choice

Precision means selecting the word that most accurately conveys the intended meaning. Clarity means the reader immediately understands what the writer is saying—no confusion, no ambiguity.

The ACT tests this by giving you a word or phrase in the passage and asking you to choose the best replacement from four options. All four choices may be grammatically correct, but only one fits the specific context.

Key Principles

• Denotation vs. Connotation: Words can have similar dictionary meanings (denotation) but carry different emotional weight or associations (connotation). For example, thrifty, economical, and cheap all relate to spending less money, but cheap has a negative connotation.

• Specificity over vagueness: A precise word paints a clearer picture. "The dog sprinted across the yard" is more precise than "The dog went across the yard."

• Context is king: Always reread the full sentence—and often the sentences before and after—to determine what meaning the author intends.

Example

Best answer: B) innovative — it's the most precise word for the context.

Exam Focus

• Why it matters: Precision questions appear on nearly every ACT English section. They reward students who read carefully and think about meaning, not just grammar.

• Typical question patterns:

  • "Which choice most specifically describes…?"

  • "Which word best conveys the idea that…?"

  • A word is underlined, and you must pick the most fitting synonym from the choices.

• Common mistakes:

  • Choosing a word that "sounds smart" but doesn't fit the meaning of the sentence.

  • Ignoring connotation—picking a word with the right denotation but the wrong tone (e.g., cunning vs. clever).

  • Not rereading the surrounding sentences for context clues.

Concision and Eliminating Redundancy

Concision means expressing an idea in the fewest words necessary without losing meaning. Redundancy is saying the same thing twice in different words.

This is one of the most heavily tested concepts in Knowledge of Language. The ACT consistently rewards the shortest answer that preserves the full meaning of the sentence.

Common Types of Wordiness

The "DELETE" Option

On the ACT, one answer choice is sometimes "DELETE the underlined portion." Many students are afraid to pick it, but it is correct whenever the underlined text is purely redundant or adds nothing to the sentence. Do not fear DELETE—it is the right answer roughly 25–30% of the time it appears.

Memory Aid

"When in doubt, cut it out." If removing a word or phrase doesn't change the meaning or hurt the sentence, it probably shouldn't be there.

Exam Focus

• Why it matters: Concision questions are among the most frequent Knowledge of Language items. The ACT strongly favors efficient writing.

• Typical question patterns:

  • "Which choice expresses the idea most concisely?"

  • Four options of varying length; three contain redundancy or filler.

  • The DELETE or OMIT option is offered as one of the choices.

• Common mistakes:

  • Assuming the longest, most "detailed" answer must be best—on the ACT, it's usually the worst.

  • Overlooking subtle redundancy (e.g., "collaborated together" — "collaborated" already means working together).

  • Being afraid to choose the shortest option or the DELETE option.

Consistency in Style and Tone

Style refers to the level of formality, sentence structure, and vocabulary choices an author uses throughout a passage. Tone is the author's attitude toward the subject—serious, humorous, objective, passionate, etc.

The ACT expects you to keep both consistent within a passage. If a passage is written in a formal, academic style, an answer choice that uses slang or overly casual language is wrong—even if it's grammatically correct.

What to Look For

• Formality level: Match the vocabulary to the rest of the passage. A scientific essay shouldn't suddenly include "super awesome results."

• Point of view: If the passage uses third person ("researchers found"), don't switch to second person ("you can see") mid-paragraph.

• Sentence complexity: A passage with long, complex sentences shouldn't have an answer that introduces a choppy, fragmented style—and vice versa.

Example

This clashes with the formal tone. A better choice: "The spacecraft executed the landing sequence successfully."

Exam Focus

• Why it matters: Style and tone questions test your ear for writing and your ability to read in context. They appear in every ACT English section.

• Typical question patterns:

  • "Which choice is most consistent with the style and tone of the passage?"

  • An answer choice that is correct in meaning but jarringly informal (or formal) compared to the rest of the text.

  • Questions where all choices convey the same basic idea but differ in register.

• Common mistakes:

  • Judging an answer in isolation instead of in the context of the whole passage.

  • Picking a casual or humorous option because it "sounds better" to you personally, when the passage is formal.

  • Failing to notice a shift in point of view introduced by one of the answer choices.

Rhetorical Effectiveness

Rhetorical effectiveness questions ask whether the writing achieves its intended purpose. These questions go beyond grammar and style—they ask you to think like a writer or editor.

On the ACT, this category includes questions about:

• Adding or deleting a sentence: Does it support the paragraph's main idea? Is it relevant?

• Sentence placement and ordering: Where does this sentence logically belong?

• Achieving a stated goal: Does the passage (or a specific revision) accomplish what the question describes?

• Transitions and logical flow: Does the chosen word or phrase effectively connect ideas?

Strategy for "Yes/No" Questions

Many rhetorical effectiveness questions follow this format:

The answer choices are typically:

• A) Yes, because [reason]

• B) Yes, because [different reason]

• C) No, because [reason]

• D) No, because [different reason]

Step 1: Decide yes or no—this eliminates two choices immediately.
Step 2: Pick the reasoning that accurately describes why.

Strategy for "Writer's Goal" Questions

These appear at the end of a passage:

Ask yourself: What is the passage actually about? If the stated goal matches the passage's main focus, the answer is yes. If the passage only mentions the goal's topic briefly or as a side point, the answer is no.

Exam Focus

• Why it matters: Rhetorical effectiveness questions blend reading comprehension with writing skill. They tend to be the most challenging Knowledge of Language items.

• Typical question patterns:

  • "Should the writer add/delete this sentence?"

  • "For the sake of the logic and coherence of the paragraph, Sentence X should be placed…"

  • "Does this essay accomplish the writer's stated goal?"

• Common mistakes:

  • Adding a sentence just because it's "interesting" even though it's off-topic for the paragraph.

  • Choosing a transition word that sounds good but doesn't reflect the actual logical relationship (e.g., using "however" when there's no contrast).

  • On writer's goal questions, confusing a passage that mentions a topic with a passage that is primarily about that topic.

Quick Review Checklist

• Can you identify which word among several synonyms is the most precise fit for a given context?

• Do you know the difference between denotation and connotation, and can you apply it to answer choices?

• Can you spot redundancy in phrases like "return back," "advance forward," or "combine together"?

• Do you know when to choose the DELETE/OMIT option—and are you comfortable doing so?

• Can you identify the style and tone of a passage and reject answer choices that break consistency?

• Can you determine whether an added sentence supports or distracts from a paragraph's main idea?

• Do you know how to handle "Yes/No, because…" questions using a two-step elimination approach?

• Can you evaluate whether a passage fulfills a writer's stated goal?

• Do you know that shorter answers are usually (but not always) preferred on the ACT English section?

• Can you distinguish between a grammatically correct answer and the best answer in context?

Final Exam Pitfalls

1. Choosing the fanciest vocabulary word: Students often pick the most impressive-sounding word, but the ACT rewards precision, not complexity. If a simpler word fits the meaning and tone better, choose it.

2. Avoiding the shortest answer or DELETE option out of fear: The ACT English test is designed to reward concision. If the shortest option preserves the sentence's meaning, it is very likely correct. Train yourself to consider it first.

3. Reading the underlined portion in isolation: Every Knowledge of Language question depends on context. Always read at least the full sentence—and often the full paragraph—before choosing an answer.

4. Confusing "sounds good to me" with "matches the passage": Your personal writing style may differ from the passage's style. The correct answer matches the passage, not your preference.

5. Rushing through rhetorical effectiveness questions: These require careful reading of both the question stem and the reasoning in each answer choice. Skimming leads to picking the right yes/no answer but the wrong justification—which means a wrong answer.

6. Ignoring redundancy within the non-underlined portion: Sometimes the underlined phrase repeats information already stated elsewhere in the sentence. Always check whether the meaning is already covered before choosing an answer that adds detail.
