今日练习题为逻辑题,题目如下

A report that many apples contain a cancer-causing preservative called Alar apparently had little effect on consumers. Few consumers planned to change their apple-buying habits as a result of the report. Nonetheless, sales of apples in grocery stores fell sharply in March, a month after the report was issued.

Which of the following, if true, best explains the reason for the apparent discrepancy described above?

A In March, many grocers removed apples from their shelves in order to demonstrate concern about their customers’ health.

B Because of a growing number of food-safety warnings, consumers in March were indifferent to such warnings.

C The report was delivered on television and also appeared in newspapers.

D The report did not mention that any other fruit contains Alar, although the preservative is used on other fruit.

E Public health officials did not believe that apples posed a health threat because only minute traces of Alar were present in affected apples.


正确答案:

A


题目解析:

Premise:报道有问题的苹果产生很小影响,很少人会改变购买习惯。

Conclusion:然而销量还是下滑了。

问题是best explain,那么就要解释因果关系论证。

因为不是削弱,是加强,所以B,C很容易排除,无关选项。

D选项虽然可以联想其他水果会卖得更好所以这个苹果就相应少了,但是可以理解为间接因果关系,没有对直接因果关系进行论证,也就是没有让premise涵盖conclusion。

E选项也是无关选项,并不能起到任何加强或削弱。

所以选A。
