Reading Comprehension of Short Passages
What the questions test
Most ACCUPLACER ESL reading items give you a short paragraph of two to six sentences and ask about the main idea, a supporting detail, an inference, or a word in context. Treat each paragraph as a small argument or description with one central point and a few facts that back it up.
Concepts to master
- Topic vs. main idea. The topic is what the passage is about (one or two words); the main idea is the claim the writer makes about that topic (a full sentence). "City parks" is a topic; "City parks improve residents' health" is a main idea.
- Supporting details answer who, what, when, where, why, or how. They are usually true statements that serve the main idea, not the point itself.
- Inference means a conclusion the passage strongly implies but does not state. Safe inferences rest on stated evidence; wild guesses do not.
Traps to watch for
- True but off-topic. A choice may repeat a detail from the passage yet fail to state the main idea. Ask: does this cover the whole paragraph, or just one sentence?
- Too broad or too narrow. "All cities should build parks" is broader than the passage; "one park opened in 2010" is narrower.
- Inference overreach. If the passage says a student "rarely missed class," inferring "she never missed class" is too strong. Words like always, never, all are red flags.
- Detail questions with swapped words. The passage says the meeting is on Tuesday; a choice says Thursday. Re-check the exact wording.
Rule of thumb
For main-idea questions, cover the answer choices and state the point in your own words first, then pick the closest match. For inference, find the sentence that supports your choice; if you cannot point to it, the inference is probably wrong.
Worked example: "Many schools now start classes later in the morning. Studies show that teenagers who begin school after 8:30 a.m. get more sleep and concentrate better in their first classes." Main idea: later start times benefit teenage students. A choice saying "teenagers need eight hours of sleep" is a true general fact but not the passage's point.
