The ACT English section tests rhetorical skills—your ability to analyze and improve writing for strategy, organization, style, and transitions. These questions ask you to evaluate whether a passage achieves its purpose effectively, flows logically, and uses precise language. For example, you might see a question like: "Which choice best introduces the main idea of the paragraph?" or "For the sake of cohesion, where should Sentence 3 be placed?" Mastering these skills helps you score higher by identifying the most concise, clear, and purposeful writing.
Example: A passage arguing for school uniforms has a persuasive strategy.
Organization (Logical Flow): The order of ideas must make sense. Look for topic sentences, transitions, and paragraph unity.
Example: A paragraph about the causes of climate change should not suddenly discuss solutions without a transition.
Style (Tone & Word Choice): The author’s attitude (e.g., formal, casual, sarcastic) and precise language.
Example: "The experiment was botched" (informal) vs. "The experiment failed to produce results" (formal).
Transitions (Cohesion): Words/phrases that connect ideas (e.g., however, in addition, as a result).
Example: "She studied hard; consequently, she aced the test."
Conciseness: The ACT prefers shorter, clearer phrasing. Avoid redundancy.
Example: "At this point in time" → "Now"
Relevance: Every sentence should support the main idea. If a sentence doesn’t fit, it’s likely wrong.
Example: A paragraph about solar energy shouldn’t include a sentence about car engines.
Topic Sentence: The first sentence of a paragraph should introduce the main idea.
Example: "The Industrial Revolution drastically changed urban life." (Sets up the paragraph’s focus.)
Supporting Details: Sentences that explain, prove, or expand the topic sentence.
Example: "Factories created jobs, but pollution increased." (Supports the topic sentence above.)
Contrast Transitions: Signal opposing ideas (however, on the other hand, nevertheless).
Addition Transitions: Build on ideas (furthermore, in addition, moreover).
Dangling Modifier: A phrase that doesn’t clearly modify the right word.
Example: "Running late, the bus was missed." (Who was running late? Fix: "Running late, she missed the bus.")
Parallel Structure: Items in a list must have the same grammatical form.
Correction: Every sentence must support the main idea. If it doesn’t, it’s wrong.
Mistake: Ignoring transitions and picking an answer that disrupts flow.
Correction: Read the sentence before and after the underlined portion to ensure logical connection.
Mistake: Selecting wordy or redundant phrasing.
Correction: The ACT prefers concise, direct language. Shorter is usually better.
Mistake: Misplacing a sentence because it seems interesting rather than logical.
Correction: Ask: Does this sentence introduce, support, or conclude the idea?
Mistake: Overlooking tone mismatches (e.g., informal language in a formal passage).
Answer: B – It directly explains why solar panels are cost-effective (long-term savings).
Passage Excerpt: 1) Scientists often use carbon dating to determine the age of fossils. 2) The process measures the decay of carbon-14 isotopes. 3) Carbon dating assumes a constant rate of decay. 4) Recent studies suggest environmental factors can alter decay rates.
Answer: C (After Sentence 3) – The sentence contrasts with the assumption in Sentence 3.
Answer: B – It’s formal, precise, and objective.
