5.2 Locating Supporting Details & Direct Facts
Key Takeaways Explain This Topic AI
Supporting detail questions comprise roughly 35% to 40% of Paragraph Comprehension questions on the AFQT, making them the most common question type.
Direct detail questions test explicit facts stated in the text and require 100% factual alignment without extrapolation.
Targeted keyword scanning allows test-takers to locate relevant sentences in the passage within 10 to 15 seconds.
Correct detail choices almost always utilize paraphrasing and synonyms rather than verbatim text copying to test semantic understanding.

5.2 Locating Supporting Details & Direct Facts
AFQT Focus: Supporting detail items represent the highest volume question type on the Paragraph Comprehension subtest, accounting for roughly 4 out of every 10 questions. Unlike main idea or inference items, supporting detail questions test your ability to locate and verify explicitly stated facts . The gold rule for supporting details is simple: If it is not explicitly written in the passage, it is incorrect.
Mastering direct fact questions is essential for securing easy points on the AFQT. However, test writers design clever distractor traps—such as changing a single modifier, altering a numerical value, or misattributing a cause—to trick test-takers who rely on superficial memory rather than strict textual verification.
The Three-Step Keyword Scanning System
Because CAT-ASVAB testing enforces strict time constraints (2 minutes per passage), you should never re-read an entire passage word-for-word to answer a detail question. Instead, execute the Three-Step Keyword Scanning System : +-----------------------------------------------------------------------+
- | THREE-STEP KEYWORD SCANNING SYSTEM |
- +-----------------------------------------------------------------------+
- | STEP 1: Identify Anchor Keywords in the Question Stem |
- | (Proper nouns, numbers, dates, specialized technical terms) |
- | STEP 2: Execute a Visual Sweep to Locate Key Terms in Passage |
- | (Scan vertically or in reverse Z-patterns) |
- | STEP 3: Perform Sentence-Level Verification & Paraphrase Matching |
- | (Verify subject, verb, condition, and numeric qualifiers) |
- +-----------------------------------------------------------------------+
- Step 1: Identify Anchor Keywords in the Question Stem
Examine the question stem and extract 1 or 2 Anchor Keywords . High-value anchor keywords include:
- Proper Nouns & Acronyms: JP-8 Fuel, M1A2 Abrams, DTIC, CENTCOM
- Numerical Values & Metrics: 1,200 °F, 45 minutes, 3.5 bar, 15%
- Specialized Terminology: viscosity, cavitation, thermal expansion, telemetry
- Step 2: Execute a Visual Sweep
Move your eyes across the text rapidly without reading for context. Search specifically for the shape of your anchor keywords (capital letters, numbers, or unique character combinations). Once you locate the keyword in the passage, freeze your reading focus on that exact sentence.
Step 3: Sentence-Level Verification & Paraphrase Matching
Read the target sentence carefully, along with the sentence immediately preceding and following it. Compare the passage's claim against the four answer choices. Remember: Correct answers rarely copy the passage verbatim. Instead, test writers use synonyms and restructured syntax (paraphrasing) to ensure you understand the meaning rather than just matching visual shapes.
Sample Passage & Step-by-Step Detail Analysis
Read the technical military passage below and examine how to verify a specific stated detail:
The Amphibious Assault Vehicle (AAV7A1) relies on a turbocharged V-8 multi-fuel engine capable of producing 525 horsepower. To prevent thermal degradation during high-speed water operations, the cooling system utilizes a dual-loop heat exchanger that transfers engine heat directly to surrounding sea water. Maintenance protocols mandate that technicians inspect coolant contamination levels after every 50 operating hours or immediately following any operation in water with high salinity. If sediment buildup exceeds 0.5 millimeters inside the primary heat exchanger tubes, thermal transfer efficiency drops by over 20 percent, triggering automatic engine derating to prevent catastrophic block warping.
Detail Question Walkthrough:
Question: According to the passage, what triggers an automatic reduction in engine power (derating)?
Identify Anchor Keywords: "automatic reduction", "engine power", "derating", "triggers".
Scan Passage: Locate "automatic engine derating" in the final sentence.
Verify Sentence Context: The text states: " If sediment buildup exceeds 0.5 millimeters inside the primary heat exchanger tubes, thermal transfer efficiency drops by over 20 percent, triggering automatic engine derating... "
Evaluate Answer Choices: Look for a paraphrase of sediment buildup exceeding 0.5 millimeters in the primary heat exchanger.
Breakdown of Distractor Traps in Direct Fact Items
Understanding how test writers alter correct statements into plausible wrong answers will prevent you from choosing false options:
Distractor Pattern How Test Writers Create It How to Spot & Avoid It
Partial Truth Trap Combines 90% accurate text with 1 altered detail (e.g., changing after 50 hours to before 50 hours ). Verify every single word in the choice against the text; if one word is wrong, the entire choice is wrong.
Wrong Subject / Misattribution Takes a true fact from sentence A and attaches it to a subject from sentence B. Ensure the action or condition matches the exact noun performing it in the passage.
Verbatim Shape Trap (Fake Match) Copies exact phrasing from the text but uses it to answer a completely different question. Do not pick an answer simply because it "looks identical" to a line in the reading.
Qualifier Swap Trap Changes absolute or restrictive modifiers (e.g., changing frequently to always , or some to all ). Pay close attention to words like always, never, only, primary, minimum, maximum .
Verbatim Traps vs. Valid Paraphrases
Consider how a single factual point is tested:
Passage Text: " High humidity accelerates the corrosion of unsealed aluminum airframes. "
Verbatim Trap Choice (Incorrect): " High humidity unseals aluminum airframes during flight. " (Uses passage words but distorts the verb relationship).
Valid Paraphrase Choice (Correct): " Moisture in the air speeds up rust and deterioration on bare aluminum structures. " (Uses synonyms: moisture in air = high humidity , speeds up = accelerates , rust/deterioration = corrosion , bare = unsealed ).
Always favor an accurate paraphrase over a misleading verbatim copy.
