Key Takeaways

  • The Reading Comprehension Test has 20 questions in 30 minutes, so accuracy matters more than speed-for-speed's-sake.
  • Correct answers are supported by the passage; they do not require outside knowledge.
  • Main idea, inference, tone, and detail questions all become easier when you track the author's purpose paragraph by paragraph.
  • Do not choose an answer just because it sounds true in real life; choose the one the passage actually supports.
  • A short note in the margin or on scratch paper about the passage structure can prevent rereading.

Reading Comprehension Test

The SIFT Reading Comprehension Test (RCT) gives you 20 questions in 30 minutes. Compared with the opening visual sections, this is a calmer part of the test, but it still punishes careless reading.

What RCT Usually Tests

Question TypeWhat You Must Do
Main ideaIdentify the passage's central claim
DetailFind what the passage explicitly states
InferenceChoose what is strongly supported, not merely possible
Author purposeRecognize why the passage was written
Vocabulary in contextUse surrounding meaning, not your favorite dictionary definition

A Reliable Method

Step 1: Read for structure

After each paragraph, ask:

  • What was this paragraph doing?
  • Was it defining, giving evidence, contrasting, or concluding?

Step 2: Read the question carefully

Many wrong answers come from solving the wrong problem. A main-idea question and a detail question require different levels of focus.

Step 3: Eliminate unsupported choices

An answer can sound smart and still be wrong if the passage does not support it.

Red Flags in Wrong Answers

Wrong-Answer PatternWhy It Fails
Too broadGoes beyond what the passage claims
Too narrowFocuses on one detail instead of the whole
True in generalMay be true, but not supported by this passage
Extreme wordingUses words like always, never, completely without support
Half-rightStarts correctly, then adds unsupported language

Micro-Passage Example

Army aviation candidates often focus on memorizing aviation trivia, but many score gains come from strengthening weaker areas such as calculator-free math, reading discipline, and spatial orientation. A balanced study plan usually outperforms a one-topic cram session.

From that passage:

  • The main idea is balanced study beats narrow cramming.
  • A supported detail is that candidates often focus too much on aviation trivia.
  • A valid inference is that broad preparation is usually more effective than overloading one category.

Time Management

You have about 1.5 minutes per question, but passages and item difficulty vary. A good rule is:

  • Read actively once
  • Answer from evidence
  • Reread only the exact lines you need

That is faster than reading the passage three times because you were passive the first time.
