Which of the following most logically completes the argument? The growing popularity of computer-based activities was widely predicted to result in a corresponding decline in television viewing. Recent studies have found that, in the United States, people who own computers watch, on average, significantly less television than people who do not own computers. In itself, however, this finding does very little to show that computer use tends to reduce television viewing time, since __________. A. many people who watch little or no television do not own a computer B. even though most computer owners in the United States watch significantly less television than the national average, some computer owners watch far more television than the national average C. computer owners in the United States predominantly belong to demographic groups that have long been known to spend less time watching television than the population as a whole does D. many computer owners in the United States have enough leisure time that spending significant amounts of time on the computer still leaves ample time for watching television E. many people use their computers primarily for tasks such as correspondence that can be done more rapidly on the computer, and doing so leaves more leisure time for watching television
说own computer 引起 less television,题目说要我们 weaken the argument.也就是说 不是 own computer 引起的 less television, 那么这时候我们要 新引入一个原因 来证明 它才是引起的 less television。 C 选项 说 own computer 的人大多数都是属于一种人群,那么说明不是 是否拥有 computer来 less television, 而是 这样的一个特定人群(比如年轻人)导致 less television。 DE 选项都强调 own computer 的人是有时间来看电视的,但是依然没解释为什么people who own computers watch, on average, significantly less television than people who do not own computers。也没引入新的原因 去取代own computer 这个原因 来导致 less television。
