Many gardeners believe that the variety of clematis vine that is most popular among gardeners in North America is jackmanii. This belief is apparently correct since, of the one million clematis plants sold per year by the largest clematis nursery in North America, ten percent are jackmanii.
Which of the following is an assumption on which the argument depends?
选项
A、The nursery sells more than ten different varieties of clematis.
B、The largest clematis nursery in North America sells nothing but clematis plants.
C、Some of the jackmanii sold by the nursery are sold to gardeners outside North America.
D、Most North American gardeners grow clematis in their gardens.
E、For all nurseries in North America that specialize in clematis, at least ten percent of the clematis plants they sell are jackmanii.
答案
A
解析
Argument Construction
Situation Of the clematis plants sold by the largest clematis nursery in North America, 10 percent are jackmanii, which many gardeners believe to be the most popular variety of clematis in North America.
Reasoning What must be true in order for the fact that 10 percent of the clematis sold at the nursery are jackmanii to provide evidence that jackmanii is the most popular variety of clematis in North America? The argument assumes that sales of different varieties of clematis at the nursery reflect the relative levels of popularity of those varieties among North American gardeners. It also assumes that jackmanii is the best-selling clematis variety at the nursery, an assumption which requires that ess than 10 percent of the nursery’s clematis sales are of any one variety other than jackmanii.
A Correct. Suppose the nursery sold ten or fewer varieties of clematis. Then at least one variety other than jackmanii would have to account for at least 10 percent of the nursery’s clematis sales, so jackmanii would not be the best-selling clematis variety at the nursery as the argument assumes.
B The argument only concerns how popular jackmanii is relative to other varieties of clematis, not relative to any plants other than clematis that the nursery may sell.
C If anything, this would weaken the argument by suggesting that the nursery’s jackmanii sales might refect jackmanii’s popularity outside North America more than its popularity within North America.
D This would indicate that clematis is a popular plant among North American gardeners, not that jackmanii is the most popular variety of clematis.
E Even if jackmanii accounts for less than 10 percent of clematis sales at a few individual nurseries, it may still account for 10 percent or more of North American clematis sales overall.
The correct answer is A.
