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.作者: snowmelt 时间: 2011-11-9 01:17
