ACT Reading: Make Inferences Using the Two-Sentence Rule

Inference questions ask what the passage suggests without explicitly stating it. The key: inferences must be supported by at least two clues in the passage, not by your outside knowledge. To answer an inference question, (1) identify what the passage explicitly states about the subject. (2) Look for patterns, tone shifts, or cause-and-effect relationships that imply a conclusion. (3) Cross-check your inference against the passage twice to ensure it is supported, not just plausible. A conclusion that could be true but is not supported by text is a trap answer; ACT inference questions have a textual anchor.

Example: A passage describes a scientist conducting experiments late into the night, skipping meals, and obsessively checking data. The passage never states "She was dedicated," but the pattern of behaviors implies it. Two supports: (1) staying late and (2) obsessive checking. Together, they justify the inference. A trap answer might be "She was anxious," which could be true but is not as directly supported as "dedicated."

Type 1: "The passage suggests that..." Look for indirect statements supported by context. Type 2: "It can be inferred that..." This is explicitly asking you to read between the lines; find the textual anchor. Type 3: "The author implies..." Look for tone, word choice, or organization that reveals attitude without direct statement. Identifying the type tells you what kind of evidence to search for before you read the choices.

Strategy: For each choice, ask: "Does the passage provide at least two clues supporting this?" If only one clue or zero clues support the choice, eliminate it. If the choice is emotionally appealing but weakly supported, it is a trap.

Find five ACT Reading inference questions from a practice test. For each question, (1) re-read the relevant passage section, (2) underline at least two textual clues supporting the correct answer, (3) for three wrong answers, explain why they are not supported. (4) Do this without looking at the answer key first. Then check your reasoning against the official explanation. This four-step approach trains you to distinguish supported inferences from trap answers that merely sound plausible.

Common wrong-answer patterns: (1) Extreme language ("always," "never") not supported by text. (2) Reversal of the actual inference. (3) Outside knowledge not mentioned in passage. (4) Correct inference stated in language too specific or too vague compared to textual support. Recognizing these patterns accelerates your elimination process.

Inference questions comprise 15-20% of ACT Reading and reward careful, methodical reading. Many students guess because they feel inference is "too subjective," but it is not; it follows the two-clue rule. Mastering inference questions gives you 2-3 reliable points per passage section, a major score boost.

This week, drill five inference questions daily using the two-clue rule. By test day, you will approach inference with confidence, not guesswork.
