Banning cigarette advertisements in the mass media will not reduce the number of young people who smoke. They know that cigarettes exist and they know how to get them. They do not need the advertisements to supply that information.
　　The above argument would be most weakened if which of the following were true?
　　(A) Seeing or hearing an advertisement for a product tends to increase people's desire for that product.
　　(B) Banning cigarette advertisements in the mass media will cause an increase in advertisements in places where cigarettes are sold.
　　(C) Advertisements in the mass media have been an exceedingly large part of the expenditures of the tobacco companies.
　　(D) Those who oppose cigarette use have advertised against it in the mass media ever since cigarettes were found to be harmful.
　　(E) Older people tend to be less influenced by mass-media advertisements than younger people tend to be.

答案选A。其实我不大懂这类的削弱题。题目是 “ 禁止吸烟的广告不会减少青少年吸烟的数量。青少年知道怎么去获得烟，他们不用广告去告诉他们这些信息。” 那么选择一个削弱的选项。怎么会是A的 广告使青少年耳濡目染让他们想吸烟呢？我觉得这并没有削弱。我觉得削弱最后的目的应该是证明广告可以阻止他们吸烟。
所以我不知道这道题要求削弱什么？
肯定是我的理解有问题，对“削弱”对象没搞清楚。
求NN帮忙解释！！谢谢！！！

额 非NN一枚 逻辑也是大难题
正如你所说的“题目是 “ 禁止烟草广告不会减少青少年吸烟的数量。青少年知道怎么去获得烟，他们不用广告去告诉他们这些信息。” 这个是基于一个假设，就是烟草广告只是告诉青少年去获得烟的信息，实际上明显不只，它们可能会通过广告激发青少年的吸烟欲望，从另一个方面指出了这类广告的危害，所以禁止这类广告是可能”reduce the number of young people who smoke“
不知道能不能帮到你！！^^
