烦请各位G友帮忙解释一下下面的题目：

A researcher studing drug addicts found that, on average, they tend to manipulate other people a great deal more than nonaddicts do. The researcher concluded that people who frequently manipulate other people are likely to become addicts.

which of the following, if true, most seriously weakens the researcher's conclusion?

(A）After becoming addicted to drugs, drug addicts learn to manipulate other people as a way of obtaining drugs.

(B) When they are imprisioned, drug addicts often use their ability to manipulate other people to obtain better living conditions.

(C) Some nonaddicts manipulate other people more than some addicts do.

(D）People who are likely to become addicts exhibit unusual behavior patterns other than frequent manipulation of other people.

(E) The addicts that the researcher studied were often unsuccessful in obtaining what they wanted when they manipulated other people.

正确答案是A. 看了OG的解释，我还是想不明白，所以请哪位nn帮忙理一下逻辑思路。

答案(A)明确了addicated和manipulate之间为因果关系，Addicated 为因而manipulate为果，因果关系是不能反过来推的。

The argument points out that there seems to be a relationship between people manipulate other people and people addicted, then concludes that: people manipulate other people --> people addicted

Weaken: people addicted --> people manipulate other people

不知道现在解释是不是已经过期了。。。
文中的they指代addicts
意思是研究发现有毒瘾的人（addicts）比没有毒瘾的人更喜欢利用别人，所以结论是如果一个人喜欢利用别人意味着这种人更容易染毒

削弱题有一种方法就是反向削弱
如果文章结论A导致B，要削弱此结论的话，可以通过选项解释其实是B导致A，这样就说明文中的结论是错误的，达到削弱效果

简单说 研究人员发现现象

drug addicts tend to manipulate other people a great deal more than nonaddicts do

于是结论 people who frequently manipulate other people are likely to become addicts.

问题是 我们并不知道究竟是manipulate other people 发生在addict之前还是之后

如果是之前 那么结论成立

如果是之后 那么结论错误 也有可能是人们因为addict才变得tend to manipulate other people

所以A正确
