1. The growing popularity of computer-based activities was widely expected to result in a decline in television viewing, since it had been assumed that people lack sufficient free time to maintain current television-viewing levels while spending increasing amounts of free time on the computer. That assumption, however, is evidently false: in a recent mail survey concerning media use, a very large majority of respondents who report increasing time spent per week using computers report no charge in time spent watching television.
Which of the following would it be most useful to determine in order to evaluate the argument? A. Whether a large majority of the survey respondents reported watching television regularly B. Whether the amount of time spent watching television is declining among people who report that they rarely or never use computers C. Whether the type of television programs a person watches tends to change as the amount of time spent per week using computers increases D. Whether a large majority of the computer owners in the survey reported spending increasing amounts of time per week using computers E. Whether the survey respondents’ reports of time spent using computers included time spent using computers at work Key: E
2. In Kravonia, the average salary for jobs requiring a college degree has always been higher than the average salary for jobs that do not require a degree.

Therefore, the average salary for all workers in Kravonia is likely to increase over the next four years.

A. Kravonians with more than one college degree earn more, on average, than do Kravonians with only one college degree. B. The percentage of Kravonians who attend college in order to earn higher salaries is higher now than it was several years ago. C. The higher average salary for jobs requiring a college degree is not due largely to a scarcity among the Kravonian workforce of people with a college degree. D.

3. In January of last year the Moviemania chain of movie theaters started propping its popcorn in canola oil, instead of the less healthful coconut oil that it had been using until then. Now Moviemania is planning to switch back, saying that the change has hurt popcorn sales.

Which of the following, if true, most strongly supports the argument against Moviemania’s claim? A. Total sales of all refreshments at Moviemania’s movie theaters increased by less than 5 percent last year. B. Moviemania makes more money on food and beverages sold at its theaters than it does on sales of movie tickets. C. Moviemania’s customers prefer the taste of popcorn popped in coconut oil to that of popcorn popped in canola oil. D.

4. Kernland imposes a high tariff on the export of unprocessed cashew nuts in order to ensure that the nuts are sold to domestic processing plants. If the tariff were lifted and unprocessed cashews were sold at world market prices, more farmers could profit by growing cashews. However, since all the processing plants are in urban areas, removing the tariff would seriously hamper the government’s effort to reduce urban unemployment over the next five years.
Which of the following, if true, most seriously weakens the argument? A.Some of the by-products of processing cashews are used for manufacturing paints and plastics. B. Other countries in which cashews are processed subsidize their processing plants. C.More people in Kernland are engaged in farming cashews than in processing them. D.Buying unprocessed cashews at lower than world market prices enables cashew processors in Kernland to sell processed nuts at competitive prices. E.A lack of profitable crops is driving an increasing number of small farmers in Kernland off their land and into the cities Key: E
5. The following appeared in a memorandum written by the chair of the music department to the president of Omega University: “Mental health experts have observed that symptoms of mental illness are less pronounced in many patients after group music-therapy sessions, and job openings in the music-therapy field have increased during the past year. Consequently, graduates from our degree program for music therapists should have no trouble finding good positions. To help improve the financial status of Omega University, we should therefore expand our music-therapy degree program by increasing its enrollment targets.”
