Q14:
The average hourly wage of television assemblers in Vernland has long been significantly lower than that in neighboring Borodia. Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold annually in Borodia has not changed. However, recent statistics show a droip in the number of television assemblers in Borodia. Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.
Which of the following is an assumption on which the argument depends?
A. The number of television assemblers in Vernland has increased by at least as much as the number of television assemblers in Borodia has decreased.
B. Televisions assembled in Vernland have features that televisions assembled in Borodia do not have.
C. The average number of hours it takes a Borodian television assembler to assemble a television has not decreased significantly during the past three years.
D. The number of televisions assembled annually in Vernland has increased significantly during the past three years.
E. The difference between the hourly wage of television assemblers in Vernland and the hourly wage of television assemblers in Borodia is likely to decrease in the next few years.

Q19:
Environmental organizations want to preserve the land surrounding the Wilgrinn Wilderness Area from residential development. They plan to do this by purchasing that land from the farmers who own it. That plan is ill-conceived: if the farmers did sell their land, they would sell it to the highest bidder, and developers would outbid any other bidders. On the other hand, these farmers will never actually sell any of the land, provided that farming it remains viable. But farming will not remain viable if the farms are left unmodernized, and most of the farmers lack the financial resources modernization requires. And that is exactly why a more sensible preservation strategy would be to assist the farmers to modernize their farms to the extent needed to maintain viability.
In the argument as a whole, the two boldface proportions play which of the following roles?
A. The first presents a goal that the argument rejects as ill-conceived; the second is evidence that is presented as grounds for that rejection.
B. The first presents a goal that the argument concludes cannot be attained; the second is a reason offered in support of that conclusion.
C. The first presents a goal that the argument concludes can be attained; the second is a judgment disputing that conclusion.
D. The first presents a goal, strategies for achieving which are being evaluated in the argument; the second is a judgment providing a basis for the argument’s advocacy of a particular strategy.
E. The first presents a goal that the argument endorses; the second presents a situation that the argument contends must be changed if that goal is to be met in the foreseeable future.

Q21:
Telomerase is an enzyme that is produced only in cells that are actively dividing. For this reason it is generally absent from body tissues in adults. Bone marrow is an exception to this rule, however, since even in adults, bone marrow cells continually divide to replace old blood cells. Cancers are another exception, because their cells are rapidly dividing.
The information provided most strongly supports which of the following?
A. Telomerase is the only enzyme that is present in cancerous cells but absent from cells that are not actively dividing.
B. In children, the only body tissues from which telomerase is absent are those in which cells are not rapidly dividing.
C. The presence of telomerase in bone marrow is no indication of bone marrow cancer.
D. Cancer of the bone marrow develops more rapidly than cancer growing in any other kind of adult tissue.
E. The level of telomerase production is always higher in cancerous tissue than in noncancerous tissue.

Q22:
Astronomer: Observations of the Shoemaker-Levi comet on its collision course with Jupiter showed that the comet broke into fragments before entering Jupiter’s atmosphere in 1994, but they did not show how big those fragments were. Nevertheless, some indication of their size can be inferred from spectrographic analyses of Jupiter’s outer atmosphere. After the fragments’ entry, these analyses revealed unprecedented traces of sulfur. The fragments themselves almost certainly contained no sulfur, but astronomers believe that the cloud layer below Jupiter’s outer atmosphere does contain sulfur. Since sulfur would have seeped into the outer atmosphere if comet fragments had penetrated this cloud layer, it is likely that some of the fragments were at least large enough to have passed through Jupiter’s outer atmosphere without being burned up.
In the astronomer’s argument, the two portions in boldface play which of the following roles?
A. The first is a claim that the astronomer seeks to show is true; the second acknowledges a consideration that weighs against the truth of that claim.
B. The first is a claim that the astronomer seeks to show is true; the second provides evidence in support of the truth of that claim.
C. The first and the second are each considerations advanced in support of the conclusion of the argument.
D. The first provides evidence in support of the conclusion of the argument; the second is that conclusion.
E. The first is a circumstance for which the astronomer seeks to provide an explanation; the second acknowledges a consideration that weighs against the explanation provided by the astronomer.

Q32:
Press Secretary: Our critics claim that the 
resident’s recent highway project cancellations demonstrate a vindictive desire to punish legislative districts controlled by opposition parties. They offer as evidence the fact that 90 percent of the projects canceled were in such districts. But all of the canceled projects had been identified as wasteful in a report written by respected nonpartisan auditors. So the 
resident’s choice was clearly motivated by sound budgetary policy, not partisan politics.
Which of the following is an assumption on which the press secretary’s argument depends?
A. Canceling highway projects was not the only way for the 
resident to punish legislative districts controlled by opposition parties.
B. The scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the 
resident’s party.
C. The number of projects canceled was a significant proportion of all the highway projects that were to be undertaken by the government in the near future.
D. The highway projects canceled in districts controlled by the 
resident’s party were not generally more expensive than the projects canceled in districts controlled by opposition parties.
E. Reports by nonpartisan auditors are not generally regarded by the opposition parties as a source of objective assessments of government projects.
