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 imprisoned, 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.
答案是A, 我感觉D也是削弱. 而且比A好, 谁能指点一下?
我怎么觉得C也可以削弱啊. 一些nonaddicts操纵别人比ADDICTS还猛, 那按照上面结论(假定它是正确的), 这些人就应该容易成为ADDICTS,但是他们并没有成为ADDICTS,所以反过来说明上面的结论不对, 从而也就削弱了啊.
我的思路是不是有问题啊? 大牛牛们给指点一下吧?

－－－－－－－－－－－C)说Some nonaddicts 怎样怎样，并不能说明任何问题，本人觉得some likely这种虚词在答案种根本不可能对，
本题是通过一个现象来得出一个conclusion，如果要是1.反对论据2.断开论据和结论的因果关系
都能够虚弱结论，可是Some nonaddicts manipulate other people more than some addicts do。既不违背题设on average, they tend to manipulate other people a great deal more than nonaddicts do.也不存在任何的加强，本人觉得some likely这种虚词在答案种根本不可能对
