1. Read the passage and answer: The Sahara Desert is the largest hot desert in the world, covering approximately 9 million square kilometers — roughly the size of the United States. Despite its harsh conditions, the Sahara is home to a variety of wildlife adapted to extreme heat and water scarcity. Camels, jerboas, fennec foxes, and various reptiles thrive there. The desert experiences temperature extremes ranging from over 50°C (122°F) during the day to near freezing at night. According to the passage, what is the approximate size of the Sahara Desert?
  1. A 1 million square kilometers
  2. B 9 million square kilometers
  3. C 50 square kilometers
  4. D 9 million square miles

Explanation

Detail questions ask for specific information stated directly in the passage. The passage states 'approximately 9 million square kilometers.' Strategy for detail questions: (1) Read the question first to know what you're looking for; (2) Scan the passage for the relevant information; (3) Verify by re-reading the specific sentence. Note distractor 4: '9 million square miles' is a unit trap — the passage says kilometers, not miles. Always read units carefully. Detail questions test reading attention; they're typically easier than main idea or inference questions because the answer is right there in the text. Don't rely on memory; refer back to the passage.

2. Read the passage and answer: Sleep is essential for human health, with most adults needing 7-9 hours per night for optimal function. During sleep, the body repairs tissues, consolidates memories, and regulates hormones. Chronic sleep deprivation has been linked to numerous health problems including obesity, diabetes, cardiovascular disease, and weakened immune function. Despite this, surveys show that approximately one-third of American adults regularly fail to get sufficient sleep. According to the passage, what percentage of American adults regularly fail to get sufficient sleep?
  1. A 10%
  2. B About 33% (one-third)
  3. C 50%
  4. D 90%

Explanation

The passage states 'approximately one-third of American adults regularly fail to get sufficient sleep.' One-third = approximately 33%. Recognize equivalent expressions: one-third = 1/3 = ~33%; one-quarter = 1/4 = 25%; one-half = 1/2 = 50%; one-fifth = 1/5 = 20%. Detail questions may ask in different terms than the passage uses; recognize numerical equivalents. Other detail-question strategies: (1) For 'who' questions — look for proper nouns and pronouns; (2) For 'when' questions — look for dates, time references; (3) For 'where' questions — look for places, locations; (4) For 'how many/much' questions — look for numbers, quantities; (5) For 'why' questions — look for reasoning, causes (often signaled by 'because,' 'since,' 'due to').

3. Read the passage and answer: The Great Pyramid of Giza, built around 2560 BC, was the tallest man-made structure in the world for over 3,800 years. It was constructed for the pharaoh Khufu of Egypt's Fourth Dynasty. The pyramid originally stood 146.6 meters tall, but erosion has reduced it to about 138 meters today. It is the only one of the Seven Wonders of the Ancient World that still largely exists. Who was the Great Pyramid built for?
  1. A Cleopatra
  2. B Pharaoh Khufu
  3. C Tutankhamun
  4. D Ramesses II

Explanation

Direct detail question — the passage states 'It was constructed for the pharaoh Khufu of Egypt's Fourth Dynasty.' Distractor analysis: other pharaohs are famous Egyptian rulers but the passage specifies Khufu. ASVAB PC includes named details — proper nouns for people, places, things. Strategy: when answering 'who/what/where/when' questions about specifics, scan for the proper noun in the passage rather than relying on memory or outside knowledge. The passage is the source of truth — even if you know something different from outside, answer based on what the passage says. If multiple specific details are given, distinguish them carefully (the pyramid was built around 2560 BC, was the tallest for 3,800 years, was originally 146.6m tall, now 138m, was built for Khufu, is the only surviving ancient wonder). Different questions could ask about each fact.

4. Read the passage and answer: A standard deck of playing cards has 52 cards divided into four suits: hearts, diamonds, clubs, and spades. Each suit has 13 cards: numbered cards from 2 through 10, plus a Jack, Queen, King, and Ace. Hearts and diamonds are red; clubs and spades are black. A standard deck does not include the jokers found in some decks. How many cards are in a standard deck?
  1. A 13
  2. B 26
  3. C 52
  4. D 104

Explanation

Direct factual question — passage states '52 cards.' Recognize numerical math: 4 suits × 13 cards per suit = 52, matching the stated total. Distractor analysis: 13 is cards per suit; 26 is half the deck (or one color); 104 is double the deck. Strategy: read carefully because numerical details can be confused — pay attention to which number answers which question. ASVAB may give multiple numbers in a passage and ask about each. Practice: read passages noting any numerical facts and what they apply to. Multiple-choice scanning: when looking for a numerical answer, scan for digits in the passage first, then verify the context.

5. Read the passage: 'The Mariana Trench, located in the western Pacific Ocean, is the deepest point on Earth. It reaches a maximum depth of approximately 36,000 feet — deeper than Mount Everest is tall. The trench was first explored in depth by the Trieste bathyscaphe in 1960, which carried scientists Jacques Piccard and Don Walsh to the bottom.' According to the passage, who first explored the Mariana Trench's depths in 1960?
  1. A Neil Armstrong and Buzz Aldrin
  2. B Jacques Piccard and Don Walsh, aboard the bathyscaphe Trieste
  3. C Charles Darwin
  4. D The passage does not specify who explored the trench

Explanation

This is a SPECIFIC DETAIL question — it asks for information explicitly stated in the passage. The passage directly states: 'The trench was first explored in depth by the Trieste bathyscaphe in 1960, which carried scientists Jacques Piccard and Don Walsh to the bottom.' So the answer — JACQUES PICCARD AND DON WALSH, aboard the TRIESTE — is directly stated. DETAIL QUESTION STRATEGY: (1) Identify what specific fact is being asked about; (2) Scan the passage to find where that topic is discussed; (3) Read carefully and select the answer that matches WHAT THE PASSAGE SAYS, not what you know from outside. AVOIDING TRAPS: (1) Outside knowledge trap — you may know other ocean explorers, but the passage specifically names Piccard and Walsh; (2) Wrong detail trap — confusing the bathyscaphe name (Trieste) with the people's names; (3) 'Not mentioned' trap — Option D claims no one is specified, but the passage clearly names them; (4) Unrelated people trap — Option A names astronauts who reached the moon, not the ocean trench. KEY PASSAGE DETAILS: Location: western Pacific Ocean; Max depth: ~36,000 feet; Comparison: deeper than Mount Everest is tall; Exploration: 1960; Vessel: Trieste bathyscaphe; Explorers: Jacques Piccard and Don Walsh. ASVAB TIP: for detail questions, always find the specific line in the passage that contains the answer rather than relying on memory of the passage. The correct answer will match the passage exactly.

6. Read: 'In 1869, John Wesley Powell became the first person to navigate the full length of the Colorado River through the Grand Canyon. His expedition of nine men departed on May 24 and completed the passage after 98 days, having lost three men who chose to leave the canyon on foot near the end. Powell himself had lost his right arm in the Civil War, yet led the expedition from a specially built chair mounted on one of the boats.' Which detail about Powell is stated in the passage?
  1. A Powell was born in Colorado
  2. B Powell had lost his right arm in the Civil War
  3. C Powell completed a second expedition the following year
  4. D Powell was appointed to lead the expedition by the president

Explanation

This is a SPECIFIC DETAIL question — the answer is directly stated in the passage and requires only that you locate the correct fact. The passage explicitly states 'Powell himself had lost his right arm in the Civil War' — this matches Option B exactly. Option A (born in Colorado) is not mentioned. Option C (second expedition) is not mentioned. Option D (appointed by the president) is not mentioned. DETAIL QUESTION STRATEGY: Go back to the passage and find the specific section about the subject of the question. Read that section carefully. Select the answer that matches the passage's exact words or meaning. The most common error on detail questions is selecting something plausible-sounding that was NOT actually in the passage — this is exactly what options A, C, and D represent. They sound like things that could be true about a historical explorer, but none appear in this passage.

7. Read: 'The three main types of rock are igneous, sedimentary, and metamorphic. Igneous rocks form from cooled magma. Sedimentary rocks form from compressed layers of sediment. Metamorphic rocks form when existing rocks are changed by heat and pressure.' According to this passage, how do metamorphic rocks form?
  1. A From cooled magma
  2. B From compressed sediment layers
  3. C When existing rocks are changed by heat and pressure
  4. D From erosion of igneous rocks

Explanation

This is a direct detail question — the answer is stated explicitly in the passage. The passage states: 'Metamorphic rocks form when existing rocks are changed by heat and pressure.' No inference or interpretation is needed. On detail questions, locate the specific sentence containing the answer and match it to an option. The other options describe igneous and sedimentary rock formation — they are in the passage but answer a different question.

8. Read: 'The M16 rifle was adopted by the US Army in 1969. It fires a 5.56×45mm NATO round and has an effective range of approximately 500 meters. Its successor, the M4 carbine, is a shorter, lighter variant adopted in 1994.' According to the passage, what caliber does the M16 fire?
  1. A 7.62×51mm NATO
  2. B 9mm
  3. C 5.56×45mm NATO
  4. D 5.45×39mm

Explanation

Direct detail: 'It fires a 5.56×45mm NATO round' — this matches Option C exactly. This is a verbatim detail question requiring only that you locate the correct fact from the text and match it. No inference is required. Common wrong answer trap: the passage mentions 1969 (M16 adoption) and 1994 (M4 adoption) — numerical distraction. Focus only on what the question asks (caliber) and locate that specific fact.

9. Read the passage and answer: The Great Wall of China was built over many centuries by several dynasties. Construction began more than 2,000 years ago, and the wall was extended and rebuilt repeatedly. Its primary purpose was defense against invasions from the north. According to the passage, what was the wall's primary purpose?
  1. A Trade
  2. B Defense against northern invasions
  3. C Tourism
  4. D Marking a border for farming

Explanation

This is a detail question, which asks for a fact stated directly in the passage. The text says the wall's 'primary purpose was defense against invasions from the north,' so the answer is defense against northern invasions. For detail questions, locate the specific statement in the passage rather than relying on outside knowledge or inference. The other choices are not supported by the passage. The correct answer restates the explicit fact: the wall was built primarily for defense against invaders from the north.

10. Read the passage and answer: Sea turtles return to the same beaches where they were born to lay their eggs. Females come ashore at night, dig a nest in the sand, and deposit dozens of eggs before returning to the ocean. The eggs hatch about two months later. According to the passage, when do female sea turtles come ashore to nest?
  1. A At dawn
  2. B At night
  3. C At midday
  4. D During storms

Explanation

This detail question asks for a directly stated fact. The passage says females 'come ashore at night' to dig their nests, so the answer is at night. Detail questions are answered by locating the exact statement in the text. The other times — dawn, midday, during storms — are not mentioned. Don't overthink detail questions or bring in outside knowledge; find the specific words in the passage. Here the text explicitly states the turtles come ashore at night.

11. Read the passage and answer: The water cycle has several stages. Water evaporates from oceans and lakes, rising as vapor. It then condenses into clouds. When the droplets grow heavy enough, they fall as precipitation — rain or snow — and the water eventually returns to bodies of water. According to the passage, what happens immediately after water evaporates?
  1. A It falls as rain
  2. B It condenses into clouds
  3. C It freezes
  4. D It returns to the ocean

Explanation

This detail question asks for the order of events as stated. The passage says water evaporates and rises as vapor, and 'then condenses into clouds.' So the step immediately after evaporation is condensation into clouds. Detail and sequence questions are answered by following the passage's stated order. Precipitation and returning to bodies of water happen later in the cycle. Track the sequence words ('then,' 'when,' 'eventually') to place each stage correctly; condensation directly follows evaporation here.
