What PC measures

Ability to read and understand written material. Combined with WK to form the VE composite, which is doubled in the AFQT formula.

What appears on the test

  • Main IdeaWhat is the passage primarily about?
  • Detail RecallAccording to the passage, what/when/where…?
  • InferenceWhat can be concluded from the passage?
  • Vocabulary in ContextWhat does "X" mean in this passage?
Worked example

Choose the answer supported by the passage

Heavy rain loosened rocks above a narrow trail. Officials closed the trail until crews could inspect the slope.

Why was the trail closed?Loose rocks created a safety hazard.
The correct answer restates evidence from the passage without adding outside assumptions.

What to study for PC

Paragraph Comprehension answers must come from the passage, not from outside knowledge. Identify the question type, locate the supporting sentence or relationship, and choose the option that says no more than the text supports.

01

Main idea

State what the whole passage is mainly doing, not one memorable supporting detail.

View key facts
  • A strong main idea covers every major sentence without becoming too broad.
  • The first sentence is often useful but is not automatically the answer.
  • Ask: “Why did the author include these details together?”
02

Supporting details

Find information explicitly stated and match it without adding an assumption.

View key facts
  • Return to the exact sentence rather than relying on memory.
  • Watch qualifiers such as “some,” “often,” and “only.”
  • A choice can use different wording and still accurately paraphrase the passage.
03

Inference

Combine stated facts to reach the smallest conclusion that must or most likely follows.

View key facts
  • An inference needs textual evidence even when it is not stated word for word.
  • Avoid dramatic conclusions when a modest one fits the evidence.
  • Reject choices that require facts not supplied in the passage.
04

Purpose and tone

Use word choice and structure to identify what the author intends and how the author sounds.

View key facts
  • Common purposes include informing, explaining, comparing, and persuading.
  • Tone labels should be supported by specific language, not by the topic alone.
  • Neutral factual passages usually do not support highly emotional tone choices.
05

Vocabulary in context

Determine what a word means in this passage, even if it has other meanings elsewhere.

View key facts
  • Substitute each choice into the sentence and check the surrounding logic.
  • Nearby examples or contrasts can define the word indirectly.
  • Choose the meaning that preserves both grammar and sense.

5 ASVAB-style practice questions

Open a question to review the choices, correct answer, and a short explanation.

Q1“Unlike rust on ordinary carbon steel, the thin oxide layer that forms on aluminum helps protect the metal beneath it from further corrosion.” The passage mainly explains:View question and answer
  1. Why all metals rust at the same rate
  2. How oxide layers are removed
  3. Why steel is lighter than aluminum
  4. How aluminum gains some corrosion resistance
Correct answerD. How aluminum gains some corrosion resistance

Why: The sentence explains that aluminum's oxide layer protects the metal beneath it, giving aluminum corrosion resistance.

Q2“The trail was closed after heavy rain loosened rocks above a narrow section. Crews will inspect the slope before reopening it.” Why was the trail closed?View question and answer
  1. Loose rocks created a safety hazard
  2. The trail was too narrow for crews
  3. The inspection had already failed
  4. Visitors damaged the slope
Correct answerA. Loose rocks created a safety hazard

Why: The passage connects heavy rain and loosened rocks to the closure, so the safety hazard is the stated reason.

Q3“The warehouse installed brighter lights near loading areas. In the following month, workers reported fewer labeling errors during the night shift.” It can reasonably be inferred that:View question and answer
  1. Night shifts were eliminated
  2. Better visibility may have reduced errors
  3. Labels were no longer required
  4. Day-shift errors increased
Correct answerB. Better visibility may have reduced errors

Why: The timing supports the modest inference that improved lighting and visibility may have contributed to fewer errors.

Q4“Some desert plants open tiny pores at night rather than during the day, limiting water loss in extreme heat.” The author's purpose is to:View question and answer
  1. Criticize desert climates
  2. Compare two deserts
  3. Explain a plant adaptation
  4. Argue against growing plants
Correct answerC. Explain a plant adaptation

Why: The passage neutrally explains how nighttime pore opening helps desert plants conserve water.

Q5“The mechanic made a preliminary inspection before beginning the full diagnostic procedure.” Preliminary most nearly means:View question and answer
  1. Final
  2. Expensive
  3. Careless
  4. Initial
Correct answerD. Initial

Why: The inspection occurs before the full procedure, so preliminary means initial or introductory.

PC study strategy

  1. Name the question type before searching the passage.
  2. Point to the exact words that support your answer.
  3. Prefer a restrained inference over one that overstates the evidence.
  4. Eliminate answers that are true in real life but unsupported by the passage.
  5. Read short passages for structure: topic, key claim, and role of each detail.
