Department Store Manager: Since 1985, when our department store enjoyed its highest sales figures ever, customers have increasingly turned to mail-order merchants for clothing and household appliances. We plan to halt this trend by reorganizing those departments in our store, simplifying our displays, and making individual items easier to find.

Which of me following, if true, most strengthens the viability of the department store’s plan?

Several airlines have recently intensified their fierce competition for business by offering tickets that, if purchased 2 days in advance, cost as much as 40 percent less than the heretofore lowest-priced “super-saver” tickets, which require a 30-day advance purchase. The airlines’ long-term gains from tickets bought under this new plan will be enormous because, unlike earlier discount tickets, these are not refundable.

The author assumes which of the following about discounted airline tickets in predicting long-term gains in airline revenue?

The gyrfalcon, an arctic bird of prey, has survived a close brush with extinction; its numbers are now five times greater than what they were when the use of DDT was sharply restricted in the early 1970’s.

Before becoming head of the department of surgery at Howard University, Dr. Charles Drew discovered that blood plasma, which keeps for months, can be used in transfusions to replace whole blood, which deteriorates in a few days when stored.

Scientists once attributed the mastodon’s extinction to the disappearance of evergreen forests at the end of the Ice Age. More recently, however, scientists have rejected that theory, hypothesizing instead that the mastodon’s extinction was caused by the draining of glacial wetlands.

Which of the following, if recently discovered, would help to account for the change in the accepted explanation of the mastodon’s extinction?

Mr. Mead: Turning this subway system over to private ownership will surely not make it financially viable. After all, the reason the system is now government-owned is precisely that in 1979 its original private owners went bankrupt operating it.

Ms. Gallis: But remember that government price controls were keeping fares unreasonably low in the 1970’s.

Of the following, the best assessment of the logical role played by Ms. Gallis’ response is that her response

The European Economic Community exported just under $400 billion in goods in 1988, sixty percent more than the United States did and nearly twice as much as Japan’s exports.

Editor: We use the computer to check the length of our articles, but surprisingly there is good reason to believe that the word count it provides is inaccurate. Several times when an article’s words were carefully counted by our most reliable copy editor, the resulting count differed from the count the computer gave.

The editor’s reasoning relies on which of the following assumptions?

Unlike the low status accorded the craftwork of many women settlers in the nineteenth-century American West, Native American women of the Plains tribes often received public recognition, wealth, and prestige for their craftwork.

Which of me following best completes the passage below?

Adding ethanol to the gasoline used in cars reduces exhaust emissions while slightly increasing evaporation from gasoline tanks in cars and service stations. These evaporative emissions are a major component of the smog found in many large cities in the hot summer months but, except in hot weather, evaporative emissions pose less of a pollution problem than exhaust emissions do. Therefore, if air pollution were the only consideration, one could conclude that —–.
