20 Paragraph Comprehension (PC) Practice Questions & Answers

1. 1. Passage: A lighthouse keeper's most tedious duty was not tending the lamp but cleaning it. Soot from the burning oil settled on the glass lenses every night, and a film too thin to notice from inside could shorten the beam's reach by miles. Keepers therefore polished the lenses each morning, in any weather, before allowing themselves to sleep. According to the passage, why did keepers polish the lenses every morning?

   • A.Cleaning the lamp was the keeper's most tedious duty.
   • B.Keepers were not permitted to sleep until after sunrise.
   • C.Even a layer of soot too thin to notice could cut how far the light reached.✓ Answer
   • D.Oil lamps stopped burning unless their glass was kept clean.

   Detail (stated and reworded fact). The passage supplies the reason outright: a film 'too thin to notice' could 'shorten the beam's reach by miles,' which option A restates in different words. On ASVAB PC detail items the key is normally a paraphrase, not a verbatim copy. B is genuinely stated in the passage but answers a different question (what was most tedious) — the single most common miss on this test. C and D introduce facts the passage never gives.

2. 2. Passage: Cast iron cookware is prized less for how quickly it heats than for how steadily it holds heat once hot. The metal is thick and dense, so it warms slowly and unevenly over a burner; but after several minutes it stores enough energy to keep its temperature nearly constant when cold food is dropped into it. Cooks who sear meat depend on that steadiness. The passage states that cooks who sear meat rely on cast iron because it:

   • A.spreads heat unevenly across the burner
   • B.is thicker and denser than other cookware
   • C.heats faster than thinner pans do
   • D.barely loses temperature when cold food is added✓ Answer

   Detail (reworded fact). The last two sentences link 'keep its temperature nearly constant when cold food is dropped into it' to what searing cooks depend on, and option B is that idea in other words. A is contradicted (the passage says it warms slowly). C and D are both true statements from the passage, but they are causes or drawbacks, not the benefit the question asks about — partially-true, true-but-irrelevant options are planted deliberately.

3. 3. Passage: The apprentice was told to arrive at the workshop at six, though the master rarely appeared before nine. In those three hours the apprentice swept the floor, sharpened every chisel, and laid out the day's timber. When the master did arrive, he began cutting at once and did not stop to hunt for a tool all morning. It can be inferred from the passage that:

   • A.the apprentice hoped one day to become a master himself
   • B.the workshop's main product was furniture
   • C.the apprentice's early hours existed so that the master's own work would not be interrupted✓ Answer
   • D.the master was lazy and avoided hard work

   Inference. A valid ASVAB inference is a small, necessary step from the text: the apprentice's three tasks (sweeping, sharpening, laying out timber) are exactly what lets the master cut 'at once' without hunting for a tool, so the early start serves the master's uninterrupted work. A over-infers a judgment the passage never licenses; B and C import information that simply is not there. Under-inferring (rejecting D because it is not stated word for word) is the other common error.

4. 4. Passage: Visitors who expect the marsh to be silent are corrected within a minute of stepping onto the boardwalk. Frogs start up in ragged waves, insects hum at a pitch that seems to come from every direction at once, and unseen birds rattle the reeds. Only in the coldest weeks of the year does the place approach the stillness people imagine. The passage indicates that the marsh is NOT:

   • A.home to frogs
   • B.quiet during most of the year✓ Answer
   • C.reachable on foot
   • D.colder at some times of year than at others

   Inference with a negative stem. NOT/EXCEPT/LEAST stems invert the task: three options are supported and you pick the odd one out. Frogs are named, a boardwalk means foot access, and 'the coldest weeks of the year' implies seasonal variation — so B, C and D are all supported. Only A is denied: the marsh approaches stillness solely in the coldest weeks, so it is noisy most of the year. Missing the word NOT is one of the most common ways strong readers lose points.

5. 5. Passage: The inspector called the crack in the beam 'superficial,' and the crew relaxed. It ran along the painted face only, stopping well short of the timber's core, and a coat of filler would hide it. Had the split reached deeper, the whole span would have had to come down. As used in the passage, the word 'superficial' most nearly means:

   • A.certain to spread over time
   • B.careless or shallow in thinking
   • C.affecting only the outer layer✓ Answer
   • D.too small to be seen at all

   Word-in-context. PC vocabulary items are decided by the surrounding sentences, not by a word's most familiar dictionary sense. Here the next sentence defines it: the crack 'ran along the painted face only, stopping well short of the timber's core' — that is D. A is the common figurative sense applied to people and is the planted trap; B is contradicted by the crew's relief; C is refuted because the inspector saw the crack.

6. 6. Passage: Early clocks were set by the sun, so noon in one town differed from noon in the next. Stagecoaches could tolerate the difference; trains could not. The railways forced the adoption of a single shared time, because a timetable means nothing if every station keeps its own hour. Stations that resisted hung two sets of hands on one dial, local and railway, before abandoning local time altogether. The main idea of this passage is that:

   • A.railway timetables made a single shared standard of time necessary✓ Answer
   • B.early clocks were inaccurate because they depended on the sun
   • C.some clock faces once carried two sets of hands
   • D.coach travel was slower and less demanding than rail travel

   Main idea. The correct choice must cover the whole paragraph, and here the topic sentence is buried in the middle ('The railways forced the adoption of a single shared time'); every other sentence sets it up or illustrates it. A is a background detail and misstates it (sun time was not inaccurate, just local). B is a passing contrast. D is a single illustration — too narrow, the classic wrong main-idea answer.

7. 7. Passage: A sourdough starter is nothing but flour, water, and patience. Left in a warm place, the mixture attracts wild yeasts and bacteria from the air and from the grain itself; fed daily, the colony grows strong enough to raise a loaf. Neglected, it sours past use. The baker does not so much create the leavening as keep a household of living organisms fed. The best title for this passage would be:

   • A.Wild Yeasts in the Air
   • B.Why Bread Goes Stale
   • C.Feeding a Living Starter✓ Answer
   • D.The Chemistry of Wheat Flour

   Main idea stated as a best title. A title must fit the whole passage and nothing beyond it. Every sentence here is about tending the starter — feed it and it thrives, neglect it and it dies — which is C, and the last sentence states it outright. A is too broad and off-topic; B is never discussed; D names one supporting detail only, making it too narrow.

8. 8. Passage: Before lifting a load, set your feet shoulder-width apart and square to the object. Bend at the knees, not the waist, and keep the load close to your body as you rise. If the object shifts or your grip slips, lower it rather than trying to correct midway. A load dropped from waist height damages far less than a back strained at full extension. The author's main purpose in this passage is to:

   • A.persuade employers to ban manual lifting
   • B.trace the history of workplace safety rules
   • C.entertain the reader with a story about an injury
   • D.instruct the reader in a safe procedure✓ Answer

   Author's purpose. Purpose answers turn on the verb, and the text is written in the imperative ('set your feet,' 'bend at the knees,' 'lower it') with each step justified — that is instruction, A. B misreads the final sentence: it explains why to drop a load, not an argument for banning lifting. C and D describe writing types (historical, narrative) that never appear here.

9. 9. Passage: The new filing system arrived with some fanfare. Staff were assured it would save each of them an hour a week; the training alone consumed three. Documents that once sat in a drawer now sit in a drawer and in two databases, and the office keeps a paper index of where the digital copies live. The author's attitude toward the new filing system is best described as:

   • A.dryly skeptical✓ Answer
   • B.sorrowful and nostalgic
   • C.enthusiastic and admiring
   • D.openly outraged

   Tone. Tone is carried by word choice and by contrast: 'some fanfare' hedges the launch, the promised one hour is set against three hours of training, and the paper index of digital files is quiet irony. That is understated skepticism, D. A reverses the tone. B and C are extreme or emotional labels; on the ASVAB, strong tone words are almost always wrong unless the passage is openly emotional, and nothing here is angry or mournful.

10. 10. Passage: Maple syrup begins as sap collected in late winter, when nights freeze and days thaw. The sap is strained to remove bark and insects, then boiled for hours until most of its water has evaporated. Only after boiling is the syrup graded by color and sealed in containers. Tapping the trees, of course, must come before any of this. According to the passage, which step happens LAST?

    • A.The sap is boiled.
    • B.The trees are tapped.
    • C.The syrup is graded by color.✓ Answer
    • D.The sap is strained.

    Sequence of events. Order words fix the chain: strained, 'then' boiled, and 'only after boiling' is it graded and sealed — so grading is last, D. The trap is that tapping is mentioned last in the paragraph but the passage explicitly places it 'before any of this'; on ASVAB sequence items the order of mention often differs from the order of occurrence, so read the time words rather than the line order.

11. 11. Passage: Rust and rot look like different problems, but both are slow fires. A rusting hinge and a decaying log are each combining with oxygen and giving off heat, only so gradually that no flame appears. Burning is simply the same reaction hurried along until the heat becomes visible. The author develops this point mainly by:

    • A.quoting an authority on the subject
    • B.comparing familiar processes to show they share one reaction✓ Answer
    • C.presenting numerical evidence
    • D.arranging events in chronological order

    Style and technique (passage organization). The paragraph names three familiar things — rust, rot, fire — and argues they are one reaction at different speeds; that structure is comparison by analogy, C. No dates or sequence appear (A), no source is quoted (B), and no figures are given (D). Style/technique is an officially listed PC concept and asks how the writing is built, not what it says.

12. 12. Passage: A carpenter's hand plane cuts by holding a blade at a fixed angle just beneath a flat sole. The sole is what makes the tool useful: it rides on the high points of a board and stops the blade from dropping into the hollows. A blade held in the hand alone would follow every dip in the surface it was meant to remove. According to the passage, the sole of the plane:

    • A.keeps the blade from dropping into hollows in the board✓ Answer
    • B.sharpens the blade as the tool moves
    • C.is the part that holds the blade at a fixed angle
    • D.adds weight so the blade cuts more deeply

    Detail (reworded fact). Sentence 2 assigns the sole exactly one job — riding the high points so the blade cannot drop into hollows — which is B. C is the seductive half-truth: the passage says the plane holds the blade at a fixed angle 'just beneath a flat sole,' not that the sole does the holding. A and D add mechanisms the text never mentions, the outside-knowledge trap.

13. 13. Passage: Desert shrubs are often spaced with a regularity that looks planted. Each stands well apart from its neighbors, with bare ground between. Where rain is scarce, a shrub's roots reach far wider than its canopy, and any seedling that sprouts inside that circle finds the water already spoken for. It can be inferred from the passage that:

    • A.the shrubs were deliberately planted in rows
    • B.the bare ground between shrubs results from competition for water✓ Answer
    • C.a shrub's canopy spreads wider than its roots
    • D.desert soil can never support a seedling

    Inference. The passage supplies the mechanism without naming the conclusion: roots reach beyond the canopy and take the water, so seedlings inside that radius fail — which is exactly why the ground between shrubs stays bare, C. A is contradicted by 'looks planted.' B reverses the stated relationship. D uses the absolute 'never'; the passage limits the effect to seedlings inside the root circle, and absolute qualifiers are usually planted wrong answers.

14. 14. Passage: The ledger's entries were fair in both senses. The clerk's hand was even and unhurried, each column aligned, so that a stranger could read the page at a glance; and the sums themselves favored no one, the shopkeeper's own debts recorded as plainly as his customers'. As used in the passage, 'fair in both senses' means the entries were:

    • A.beautiful and profitable
    • B.pale in color and pleasant to look at
    • C.easy to read and impartial✓ Answer
    • D.ordinary and merely acceptable

    Word-in-context. The passage defines both senses in order: the handwriting is even and legible ('a stranger could read the page at a glance') and the accounting favors no one — that is B. A and C are real dictionary senses of 'fair' (light-colored; merely adequate) that the context rules out, and choosing a familiar-but-wrong sense is the standard error here. D adds profit, which the passage never mentions.

15. 15. Passage: Sand dunes move. Wind rolls grains up the gentle windward slope and drops them over the crest, where they slide down the steep far face. No single grain travels far, but the dune as a whole creeps downwind, sometimes burying fences and roads. What looks like a fixed hill is really a slow river of sand. This passage is primarily about:

    • A.the damage dunes do when they bury fences and roads
    • B.the fact that a dune is a slowly moving accumulation rather than a fixed hill✓ Answer
    • C.how much harder the wind blows on the windward side of a dune
    • D.the idea that wind is responsible for every desert landform

    Main idea. The first and last sentences frame the whole paragraph — 'Sand dunes move' and 'a slow river of sand' — and the middle explains the mechanism; C captures that. A is not even stated (the passage contrasts slope shapes, not wind strength). B is one consequence, too narrow. D reaches past the passage to a claim about all desert landforms, the too-broad trap.

16. 16. Passage: A good workplace checklist is short, ordered, and read aloud. Short, because a list longer than a page is skipped under pressure. Ordered, because steps that depend on one another must be confirmed in sequence. Read aloud, because a silent check is easily imagined rather than performed. Nothing on a checklist should be a task the reader has never done. The passage names all of the following as features of a good checklist EXCEPT:

    • A.It is read out loud.
    • B.It is brief.
    • C.It includes tasks the reader has never performed.✓ Answer
    • D.Its steps are confirmed in order.

    Detail with an EXCEPT stem. The first sentence lists three features — short, ordered, read aloud — so A, B and C are all supported and cannot be the answer. The final sentence says the opposite of D: nothing on the list should be a task the reader has never done. With EXCEPT/NOT stems, verify each option against the text and pick the one the passage contradicts or omits.

17. 17. Passage: The museum keeps its oldest manuscripts in a room without windows, lit only when a visitor enters and never above a certain dimness. Guides answer the same complaint every day: yes, the room is too dark to read comfortably, and no, the lights will not be turned up. The reader can conclude from the passage that:

    • A.exposure to light damages the manuscripts✓ Answer
    • B.the manuscripts are written in a language few visitors can read
    • C.the museum cannot afford better lighting
    • D.visitors are not allowed into the room

    Inference. Three deliberate measures — no windows, light only when someone is present, and a hard ceiling on brightness — are all restrictions on light, and the museum keeps them even though visitors object. The only conclusion that explains all three is that light harms the manuscripts, B. C invents a financial motive the passage never raises; A is unrelated; D is contradicted, since visitors enter and complain.

18. 18. Passage: Readers are often told that a spider's web is a trap, as if the spider had only to wait. In truth the web is rebuilt constantly, sometimes nightly, at real cost in silk and energy. Considering the labor involved, the web is less a trap than a tool the spider must maintain, and calling it anything else hides how much work goes into it. The author's chief purpose in this passage is to:

    • A.compare several species of spider
    • B.correct a common misunderstanding✓ Answer
    • C.warn readers about the danger of spiders
    • D.explain the chemistry of silk production

    Author's purpose. The structure gives it away: a widely held belief is stated ('Readers are often told...'), then reversed ('In truth...'), then replaced with a better description. That is correction, A. B misjudges the tone — nothing here is cautionary about danger. C and D name topics the passage never takes up; picking them means importing what a spider passage 'usually' contains instead of reading this one.

19. 19. Passage: The captain ordered the crew to secure the deck. Loose crates were lashed to the rail, hatches were dogged shut, and anything that could roll was carried below. Within twenty minutes nothing on deck could shift, whatever the sea did. As used in the passage, 'secure' most nearly means:

    • A.fasten things firmly in place✓ Answer
    • B.obtain or acquire
    • C.clear of all people
    • D.guard against theft

    Word-in-context. The sentences after the order define it by example — lashing, dogging shut, carrying below, until 'nothing on deck could shift' — so the sense is fastening things down, B. A and C are ordinary dictionary meanings of 'secure' that the context rules out, and C in particular is the sense most readers reach for first. D describes clearing the deck of people, which the passage never says.

20. 20. Passage: Concrete does not dry; it cures. The water in the mix is not merely evaporating but reacting with cement to form crystals that lock together. That is why fresh slabs are kept damp, sometimes covered for days: a slab that loses its water too fast ends up weaker, not stronger, however hard the surface feels. According to the passage, fresh slabs are kept damp because:

    • A.the crystals form only in cold weather
    • B.covered concrete dries faster than uncovered concrete
    • C.a damp surface feels harder than a dry one
    • D.the water must react with the cement instead of escaping✓ Answer

    Detail (reworded fact) resting on a stated cause. The passage says the water reacts with cement to form interlocking crystals and that losing water too fast makes the slab weaker; A restates that causal chain. B contradicts the point of covering. C twists the last clause, which says the surface can feel hard even when the slab is weak. D adds a temperature condition the passage never mentions — the outside-knowledge trap.
