About This Section
The ACT Reading section tests your ability to comprehend, analyze, and evaluate written passages from a variety of subjects. You will read passages and answer questions about main ideas, supporting details, vocabulary in context, author's purpose, and logical reasoning. This is one of three required sections on the enhanced ACT (2025+).
What's Covered
- Key Ideas and Details — identifying central ideas and themes, summarizing information, drawing inferences, and understanding cause-and-effect relationships
- Craft and Structure — determining the meaning of words and phrases in context, analyzing text structure, and identifying author's purpose and point of view
- Integration of Knowledge and Ideas — evaluating arguments, distinguishing between fact and opinion, analyzing how authors use evidence, and making connections across passages
For the official section description, see the official ACT exam structure page.
Study Tips
- Read the questions before the passage. Knowing what to look for helps you read more efficiently under time pressure.
- For main idea questions, focus on the first and last sentences of each paragraph. These typically contain the key claims.
- Vocabulary-in-context questions test how a word is used in the specific passage, not its most common dictionary definition. Always reread the surrounding sentences.
- For inference questions, the answer must be directly supported by the text. Avoid answers that require outside knowledge or assumptions not in the passage.
- Pace yourself: with 36 questions in 40 minutes, you have about 67 seconds per question. Spend more time reading the passage carefully and less time deliberating on each question.

- D) A source of energy for deep-sea survival.
View Answer & Explanation
Correct Answer:
B) A tool for hunting and attracting mates.
Explanation:
The passage explicitly states that the anglerfish's lure functions 'as both a hunting tool and an attractant for potential mates.' The other options are not supported by the passage.
- A) The ocean is bright enough to see without bioluminescence.
- B) Bioluminescence is a rare adaptation in the animal kingdom.
- C) Light is crucial for survival in deep-sea ecosystems.
- D) Most deep-sea creatures are carnivorous.
View Answer & Explanation
Correct Answer:
C) Light is crucial for survival in deep-sea ecosystems.
Explanation:
The high prevalence of bioluminescence (90%) suggests it is an essential adaptation, which implies light is important for survival in deep-sea environments. The other options cannot be inferred from this statistic.
- A) It indicates that anglerfish have poor eyesight.
- B) It suggests that different individuals have unique patterns that can be recognized.
- C) It implies that the lure is brighter than other bioluminescent organisms.
- D) It demonstrates that the lure only attracts small fish.
View Answer & Explanation
Correct Answer:
B) It suggests that different individuals have unique patterns that can be recognized.
Explanation:
'Distinctive' implies uniqueness and recognizability. The passage states that opposite-sex fish recognize 'the distinctive light pattern' as a mating signal, suggesting individual recognition.
- A) The second sentence contradicts the first.
- B) The second sentence provides a specific example of the general claim in the first.
- C) The second sentence introduces a new topic unrelated to the first.
- D) The second sentence restates the first sentence in different words.
View Answer & Explanation
Correct Answer:
B) The second sentence provides a specific example of the general claim in the first.
Explanation:
The first sentence defines bioluminescence; the second provides a specific statistic about bioluminescence in deep-sea creatures, illustrating how common this adaptation is.
- A) The anglerfish would become a herbivore.
- B) The anglerfish would be unable to attract prey or mates.
- C) The anglerfish would hunt using echolocation instead.
- D) The anglerfish would migrate to shallower ocean depths.
View Answer & Explanation
Correct Answer:
B) The anglerfish would be unable to attract prey or mates.
Explanation:
The passage explains that the lure functions as both a hunting tool and attractant. Without light, both functions would fail. The other options are not supported by the passage.
