Now that you’ve wrapped up the Assumptions chapter, we’re going to move on to some trap question types and then some review questions.

Beware: Scope Trap

If you’ve found the main point, you must also identify what is in the range of the argument. Scope is related to more than just the general topic being discussed: it is the narrowing of the topic. Is the article about graduate-school admissions, law school admissions, or helping literature students get into the law school program of their choice? Each step represents a narrowing of the scope.

Let’s look at this critical reasoning question to examine scope.

Apartment building owners argue that rent control should be abolished. Although they acknowledge that, in the short term, rents would increase, they argue that the long-term effect would be a reduction in rents. This is because rent increases would lead to greater profitability. Higher profits would lead to increased apartment construction. Increased apartment construction would then lead to a greater supply of residences, and lower prices would result because potential apartment residents would have a better selection. Thus, abolishing rent control would ultimately reduce prices.

Name an assumption made by the owners:
(Hint: this is a difficult question, but you can eliminate four of the five answers as outside the scope of the argument.)

  • Current residents of rent-controlled apartments would be able to find new apartments once their rents increased.
  • The fundamental value of any society is to house its citizens.
  • Only current apartment owners would profit significantly from market deregulation.
  • New apartment construction will generate a great number of jobs.
  • The increase in the number of apartments available would exceed the number of new potential apartment residents.

Which possible answers are outside of the scope? The scope is the argument that deregulation will increase supply and lower prices. “Name an assumption” means find a direct assumption of the supply/demand argument.

(E) is the only choice that isn’t outside the scope of the argument: price of rents. So, we can choose it without even seeing a question stem. The argument revolves around a supply/demand dynamic in housing, so the answer should as well.

(A) Current residents aren’t related to the issue in the argument. It should go afield into areas that aren’t related like (B)  and (C), which is more about societal ethics. This issue of jobs isn’t mentioned either (D). (E) is the only choice directly germane to the paragraph.

Trap Answers: BEWARE OF TWINS

If two questions are the same, then both are likely wrong. This video is from the GMAT critical reasoning section, which is very similar to the LSAT logical reasoning question (GMAT students often review official LSAT questions for a challenge).
