　　1.The ancient Greek playwright Euripides followed the established conventions of verse composition less rig- orously at the end of his career than at the beginning. Since the lines from a recently discovered Euripidean play adhere to those conventions as rigorously as do lines from Euripides' early plays, the recently discov- ered play must have been composed early in Euripides’ career. Which of the following is an assumption made in the argument?

　　(A) All of Euripides' plays were written in verse.

　　(B) Euripides did not write any plays late in his career in which he imitated the style of his early plays.

　　(C) Euripides grew increasingly unaware of the established conventions of verse composition as his career progressed.

　　(D) Late in his career, Euripides was the only playwright of his day who consciously broke with the established conventions of verse composition.

　　(E) Ancient playwrights tended to be less willing to violate certain conventions early in their careers than they were late

　　2.In the United States, average fuel efficiency of newly manufactured domestic cars, although remaining worse than that of newly manufactured imported cars, substantially improved between 1983 and 1988. Average fuel efficiency of new domestic cars has not improved since, but the difference in average fuel efficiencies of new domestic cars and new imported cars has steadily decreased. If the statements above are true, which of the following must also be true on the basis of them?

　　(A) Average fuel efficiency of domestic cars manu- factured after 1988 was better than that of imported cars manufactured before 1988.

　　(B) Average fuel efficiency of newly manufactured domestic cars has steadily worsened since 1988.

　　(C) Average fuel efficiency of newly manufactured imported cars has steadily worsened since 1988.

　　(D) Average fuel efficiency of newly manufactured imported cars has steadily improved since 1983.

　　(E) Average fuel efficiency of imported cars manu- factured in 1983 was better than that of imported cars manufactured in 1988.

　　3. Between 1970 and 1980, energy consumption by United States industry peaked and then declined, so that by 1980 total industrial use of energy was below the 1970 level even though total industrial output had grown substantially in the same period. Industry must have instituted highly effective energy conser- vation measures in those years to have achieved such impressive results. Which of the following, if true, most seriously weak- ens the conclusion of the argument?

　　(A) Many industries switched to the greatest extent possible from high-priced oil to lower-priced alternatives throughout the 1970's.

　　(B) Total residential energy consumption was higher in the United States in 1980 than it had been in 1970

　　(C) Many industrial users of energy had paid little attention to energy conservation prior to 1970.

　　(D) Industrial output grew less rapidly from 1970 to 1980 than it had from 1960 to 1970.

　　(E) The industries whose production dropped sharply during the 1970's included a disproportionately large number of energy-intensive industries.

　　4.Many people acquire software programs for their home computers by illegally copying those programs rather than purchasing them. People who own home computers must be making, on average, fewer illegal copies of software programs than before, however, since the average number of software programs that people purchase to use on their home computers has increased substantially over the past five years. Which of the following, if true, most strengthens the argument?

　　(A) The number of home computers in use has increased substantially over the past five years.

　　(B) Five years ago, about half of the software pro- grams used on home computers had been illegally copied rather than purchased.

　　(C) Most people who have home computers use their computers more frequently the longer they have them.

　　(D) Few people who prefer to copy computer software programs illegally cannot copy the software programs they want because they have no acquaintances who have those software programs.

　　(E) On average, people with home computers have the same number of software programs today as people with home computers did five years ago.

　　5.From a newspaper editorial： Many people who are addicted to heroin will even- tually attempt to overcome their addiction, prin- cipally for two reasons：the expense of maintaining a heroin addiction and the fear of arrest. If heroin were legalized and made available cheaply, as some people advocate, neither of these reasons would apply The considerations above can best serve as part of an argument that

　　(A) legalizing the sale of heroin would cause the price of this drug to go down

　　(B) making it easier for heroin addicts to obtain treatment for their addiction would encourage many heroin addicts to attempt to overcome their addiction

　　(C) legalizing the sale of heroin would increase the number of crimes committed by heroin addicts to support their addiction

　　(D) making heroin available legally and cheaply would make it less likely that heroin addicts will attempt to overcome their addiction

　　(E) decreasing the severity of penalties for individuals who use heroin would not increase the number of new heroin addicts
