【GMAT考满分逻辑CR题库】Fund manager: over the last five years, the var_真题_答案

题目内容

Fund manager: over the last five years, the various stock funds managed by our company increased on average by 7 percent more in value than the market as a whole annually. Furthermore, the performance of each particular stock fund has not varied much from one year to the next, and our few investment products other than stock funds have stayed even with the market. These results show the success of our company: each year, most of our investment products have increased in value more than the market.

The debater's argument is most vulnerable to criticism on which of these grounds?

A
It takes for granted that the stock funds are typical of the company with regard to the average increase in value per year.
分析该选项
B
It takes for granted that if a certain average annual increase in value was obtained by each investment product, then each stock fund increased each year by approximately the same amount.
分析该选项
C
It confuses a claim from which the argument's conclusion about the company would necessarily follow with a claim that would follow from the argument's conclusion only with a high degree of probability.
分析该选项
D
It overlooks the possibility that even if, on average, the stock funds increased by an average annual value, many stock funds may have increased less than the market as whole.
分析该选项
E
It overlooks the possibility that even if most investment products at the company have increased in value more than the market this year, any one investment product may, in some years, fail to increase in value at all.
