Reading Comprehension
What this domain tests
The OAT Reading Comprehension section presents multi-paragraph passages drawn from natural science, social science, and humanities sources, then asks what each passage says and how it says it. Timing is tight - roughly a minute per question - so the section rewards a repeatable method rather than a slow, even read of every sentence.
Core rules and concepts
- Every answer must be defensible from the printed text. Prior science knowledge is a distractor source, not evidence.
- Stems map to a small set of tasks: main idea or primary purpose, explicit detail, inference, vocabulary in context, tone or attitude, and organization/support questions.
- Read each paragraph's first sentence carefully; topic sentences carry the passage's skeleton and let you relocate information fast.
- Track signal words - however, although, therefore, for example, in contrast - because they mark the shifts that purpose and inference items target.
- For detail items, find the keyword in the passage first, then read the sentence before and after it.
- Correct inferences are modest. If a choice requires two unstated assumptions, it is wrong.
Worked example
Passage sentence: "Although lichens tolerate prolonged drought, they grow only when wetted, and recovery after desiccation can lag hours behind the first rain." Question: The passage suggests that lichen growth following rain is (A) immediate, (B) delayed, (C) impossible, (D) independent of moisture. Reasoning: "lag hours behind the first rain" paraphrases delay, so B. A directly contradicts the sentence; C is extreme and unsupported; D is refuted by "grow only when wetted." Note that the opening although signals a concession, not the main point.
Traps that cost marks
- Selecting a true statement that does not answer the question actually asked.
- Attributing a cited researcher's or opponent's view to the author.
- Missing a capitalized NOT, EXCEPT, or LEAST and answering the reverse question.
- Choosing extreme wording (always, never, proves) where the passage hedges (may, suggests, appears).
- Sinking four minutes into one stubborn item instead of marking it and moving on.
