MCAT CARS Social Science Passage Practice Questions

By StudyStore · Published 2026-11-04 · 8 original questions · about 12 min

A free, original MCAT-style CARS social science passage with 8 questions on main idea, assumptions, scope traps, application and weakening, with full explanations.

Quick concept primer

This page gives you one original social science passage of about 570 words and eight questions: main idea, the function of an example, an unstated assumption, what the author would agree with, application to a new case, a detail EXCEPT question and weakening. Social science passages usually set a familiar explanation against the author's own, so as you read, note which view each paragraph serves and where the author limits the claim. Give yourself about ten minutes. If you want more drills with the same question types, the CARS Strategy pack adds flashcards on question types and wrong-answer patterns plus a timing and review method, and you can try the free sampler first.

Traps: in social science passages, wrong answers often turn the author's account into a universal law ("every society", "always resented") or mistake a view the author reports for one the author holds. Paragraphs 3, 5 and 6 all narrow the argument, and several questions turn on those limits.

Passage

(1) Waiting in line is usually treated as a pure cost, minutes subtracted from a day. Analysts who design queues often model them this way, as a problem of throughput: how many servers, how many arrivals, how long the average wait. That framing is useful for planning a bank lobby or a call center. It misses, however, what people in a line are doing while they wait, which is keeping up a small and surprisingly durable social order.

(2) A queue has no written rules, no officers and usually no penalty beyond a few hard looks. Yet in many places strangers who will never meet again hold their positions, defend the person behind them from a cutter, and step away briefly without losing their place, provided they tell a neighbor first. The order is maintained by the people inside it. Some sociologists describe the line as a miniature society whose members agree, without discussion, that arrival time is the fair basis for service.

(3) That agreement is neither universal nor natural. In some settings the crowd at a counter is sorted by who pushes hardest or who knows the clerk; in others, by numbered tickets from a machine. The first-come principle is a cultural choice, one that rewards patience and treats every arrival as equal regardless of status. Where it holds, it expresses a commitment to equality that the same people may not practice anywhere else in their day.

(4) This is why line-cutting provokes reactions that seem out of proportion to its cost. Someone who slips in ahead of ten others delays each of them by perhaps a minute, yet the people behind often respond with an anger they would never show over a minute lost in traffic. The anger makes sense once we see that the cutter has taken something other than time. The cutter has denied the premise that the people waiting are equals, and those who protest are defending the premise rather than the minute.

(5) Paid fast lanes at airports and amusement parks complicate the picture without overturning it. Customers in the ordinary line rarely confront those who use the premium lane, though they lose position to them just as surely as to a cutter. The difference is that the fast lane is announced in advance and open to anyone who pays. People seem to accept an unequal arrangement that is open and bound by rules more readily than an equal one that is quietly broken. What offends, on this account, is not inequality as such but the breach of a shared understanding.

(6) None of this means that queues should never be redesigned. An emergency department that treated patients strictly by arrival would be negligent, and no one waiting there expects it to. The point is narrower: planners who treat a line only as a flow of bodies to be optimized should not be surprised when a change that saves everyone time is resented as unfair. Before altering how people wait, it is worth asking what the waiting means to them.

8 practice questions

Try each question before opening the explanation. Click "Show answer and explanation" to check yourself. All questions are original and written for study practice.

Question 1

In the queue passage above, which statement best expresses the author's central thesis?

  1. Queues are an inefficient way to allocate service and should be replaced by systems that cut average waiting time.
  2. A line is sustained by a shared norm of equal treatment, so changes to it should weigh its social meaning, not only its efficiency.
  3. People resent line-cutters mainly because even short delays add up to a large total cost for everyone waiting.
  4. Paid fast lanes show that people no longer care whether service is distributed equally.
Show answer and explanation

Answer: B. A line is sustained by a shared norm of equal treatment, so changes to it should weigh its social meaning, not only its efficiency.

B joins the claim of paragraphs 2 to 4, that the line is an order of equals kept up by its members, with the advice of paragraph 6, to ask what waiting means before redesigning it. A reverses the author, who calls throughput models useful but incomplete. C is the explanation paragraph 4 rejects. D distorts paragraph 5, which says the fast lane complicates the account without overturning it.

Question 2

In the queue passage, the author compares a minute lost to a line-cutter with a minute lost in traffic (paragraph 4) primarily in order to:

  1. show that drivers are generally more patient than people standing in lines.
  2. estimate how much total time a single line-cutter costs the people behind.
  3. show that anger at cutters comes from the combined delay imposed on everyone behind.
  4. show that the anger at a cutter is not explained by the amount of time lost.
Show answer and explanation

Answer: D. show that the anger at a cutter is not explained by the amount of time lost.

The same delay produces anger in one case and not the other, which the author uses to conclude that "the cutter has taken something other than time," so D is the function. A draws a conclusion about drivers that the author never makes. B mistakes the illustrative minute for the purpose of the comparison. C is the time-cost explanation the comparison is meant to rule out.

Question 3

The queue passage's explanation of why people protest line-cutting (paragraph 4) depends on which unstated assumption?

  1. A delay caused by traffic is not experienced as a breach of a shared rule among equals.
  2. Most line-cutters know in advance how angry the people behind them will become.
  3. The people who protest a cutter have usually waited longer than the others in line.
  4. A minute in traffic usually costs a driver more than a minute in line costs a customer.
Show answer and explanation

Answer: A. A delay caused by traffic is not experienced as a breach of a shared rule among equals.

The contrast works only if the two delays differ in the one feature the author cares about: the cutter breaks a premise of equality and traffic does not, so A must be assumed. B and C are not needed, since the argument concerns why the cutting offends, not what cutters know or who protests. D would actually undermine the contrast, because a costlier traffic delay should provoke more anger, not less.

Question 4

Based on the queue passage, the author would most likely agree with which statement?

  1. Every society organizes access to services by order of arrival.
  2. Any unequal treatment of customers produces resentment in those who wait.
  3. A rule can win wide compliance even when no one is assigned to enforce it.
  4. Mathematical models of waiting lines are of no use to planners.
Show answer and explanation

Answer: C. A rule can win wide compliance even when no one is assigned to enforce it.

Paragraph 2 describes a queue with no officers and no written rules whose order "is maintained by the people inside it," so the author accepts C. A and B are extreme-language traps: paragraph 3 says the first-come principle is not universal, and paragraph 5 says open inequality is often accepted. D overstates paragraph 1, which calls the throughput framing useful for some purposes.

Question 5

A city permit office replaces its walk-in line with appointment slots that are posted online in advance and can be booked by anyone. Based on the queue passage, how would the author most likely expect the public to react?

  1. With strong resentment, because any departure from first-come service is seen as cutting
  2. With indifference, because people care only about the length of their wait
  3. With anger toward the clerks, because walk-in customers will now be turned away
  4. With less resentment than if staff quietly let acquaintances skip the walk-in line
Show answer and explanation

Answer: D. With less resentment than if staff quietly let acquaintances skip the walk-in line

Paragraph 5 argues that people accept arrangements that are open and bound by rules more readily than a quietly broken equal rule, and letting acquaintances skip is the kind of breach paragraph 3 links to who knows the clerk. A treats any change as cutting, which paragraph 5 denies. B is the pure-cost view the author rejects. C blames the clerks for a rule that is posted openly and applies to everyone, which is the kind of arrangement paragraph 5 says people accept.

Question 6

According to the queue passage, the ways crowds at a counter are sorted in some settings include all of the following EXCEPT:

  1. a lottery drawn when the counter opens.
  2. who pushes the hardest.
  3. who knows the clerk.
  4. numbered tickets issued by a machine.
Show answer and explanation

Answer: A. a lottery drawn when the counter opens.

Paragraph 3 lists pushing hardest, knowing the clerk and numbered tickets from a machine as alternatives to the first-come principle, which covers B, C and D. A lottery is never mentioned. It may sound plausible as another way to ration service, but a detail question has to be answered from the text, not from general knowledge.

Question 7

Suppose researchers established one of the following. Which finding would most weaken the queue passage's claim about paid fast lanes in paragraph 5?

  1. Paid fast lanes are being added at more airports and amusement parks each year.
  2. People who cut into lines often say afterward that they were in a hurry.
  3. Customers in ordinary lines resent premium-lane users as much as they resent cutters.
  4. Some customers who buy premium access on one visit use the ordinary line on another.
Show answer and explanation

Answer: C. Customers in ordinary lines resent premium-lane users as much as they resent cutters.

Paragraph 5 claims that an open, rule-bound inequality is accepted more readily than a quietly broken equal rule. If ordinary-line customers resent premium users as strongly as cutters, that difference disappears, so C weakens the claim. A says nothing about how the lanes are received. B concerns cutters' excuses, not reactions to fast lanes. D describes who buys access and leaves the claim about acceptance untouched.

Question 8

In the queue passage, the author mentions an emergency department in paragraph 6 primarily in order to:

  1. argue that hospitals should adopt the first-come rule that ordinary queues follow.
  2. concede that arrival order is not the right basis for service in every setting.
  3. show that planners who redesign lines are always resented for doing so.
  4. give a second example of a paid fast lane that customers accept.
Show answer and explanation

Answer: B. concede that arrival order is not the right basis for service in every setting.

The paragraph opens with "None of this means that queues should never be redesigned" and calls strict arrival order in an emergency department negligent, which is a concession that limits the thesis. A reverses the example. C turns "should not be surprised" into an absolute claim with "always," a scope trap. D confuses triage by medical need with paying for priority.
