不知道是不是我没有读懂，A选项不是增强么？我觉得C才是削弱。请指教

题中说people who manipulate othere people 更容易上瘾；（即A 是B的原因）
A：说上瘾是manipulate other people 的原因 （即B是A的原因），所以是削弱
D； 是无关，本文的focus是manipulation,是不是还有其他的behaviorpattern is not the focus of this problem.

A是列出他因，削弱

D是无关选项，直接削弱作者的事实，那是错误削弱

Drakedirect

A中并没有他因，削弱题型中有一种可以预测答案的就是这种，题中说A是B的原因，选项中说B是A的原因， 及因果颠倒削弱

写错了，应该是C

题中写：addict trend manipulate others （A->B），因此 who frenquently manipulate others are likely to be addict （B->A）。
由于 A是B的充分条件，却不一定是必要条件，所以只要给出反例就能weak

A： 解释了addict trend manipulate others，即解释了A，所以我认为是增强；
C： some noneaddict manuplate others too，即给出了反例，所以委任我是削弱

你觉得呢？

Drakedirect

文中的推理是由一个事实trend to manipulate others 推出they aer likely to be addict.的结论。

我个人认为C并不能削弱结论。即便some none addict manuplate others too 也不能推翻事实， 平均来讲，addict trend to manipulate compared to none addict.所以不对结论有任何的威胁

欢迎讨论！

你说的有道理
但我还是不明白A为什么会削弱

zjflora

原文说：爱操纵别人的人易有毒品成瘾倾向。

A：成瘾后的人，通过操纵别人取得drugs.

削弱因果有四点：给出他因，有因无果，有果无因，因果倒置

A为因果倒置。

有道题说夫妻睡眠周期不一致导致关系不和，和此类似。

原文说：夫妻睡眠周期不一致导致关系不和。

削弱的答案是：其实是因为关系不和，才导致夫妻选择与对方不同时睡眠。

错误答案：夫妻睡眠周期相同的也会关系不和。

回到你问的题目，细想一下，A削弱的程度比C大，它彻底推翻了结论，原来成瘾者不是主观意愿要操纵别人。C部分承认了有些成瘾者会操纵人。

zjflora mm讲的很详细...

我不明白为什么D不可以？

yyisme在3楼讲“D是无关选项，直接削弱作者的事实，那是错误削弱”，这是什么意思？难道说削弱事实不是削弱？我刚开始复习，所以不是很明白。
