请教FeiFei 宝典118的疑问

118. There are about 75 brand of microwave popcorn on the market altogether, they account for a little over half of the money from sales of microwave food products. It takes three minutes to pop corn in the microwave, compared to even minutes to pop corn conventionally. Yet by weight, microwave popcorn typically costs over five times as much as conventional popcorn. Judging by the popularity of microwave popcorn, many people are willing to pay a high price for just a little additional convenience.

Which one of the following statements, if true, would call into question the conclusion in the passage?

A.        More than 50 percent of popcorn purchasers buy conventional popcorn rather than microwave popcorn.

B.        Most people who prefer microwave popcorn do so because it is less fattening than popcorn that is popped conventionally in oil.

C.        The price of microwave popcorn reflects its packaging more than it reflects the quality of the popcorn contained in the package.

D.       The ratio of unpopped kernels to popped kernels is generally the same whether popcorn is popped in a microwave or conventionally in oil.

E.        Because microwave popcorn contains additives not contained in conventional popcorn, microwave popcorn weights more than an equal volume of conventional popcorn.

答案：B

典型的他因削弱。原文的结论是：因为a little additional convenience而付高额价钱。题目问：call into question。B：付高价是因为脂肪少。

A，C，D，E均为无关项。

我觉得A说：买传统爆米花的人比买微波炉爆米花的人多50%，不是在直接的weaken原文的结论吗？ 为什么不选A？

Conclusion: Judging by the popularity of microwave popcorn, many people are willing to pay a high price for just a little additional convenience.

A:
            More than 50 percent of popcorn purchasers buy conventional popcorn rather than microwave popcorn. 好象没有必然联系. 关系不大.

就是有点联系,不如B来得明显,直接. 拙见.

A选项我的理解是，超过50%的人买传统爆米花而不是微波炉爆米花。

这样就好理解了吧
