3M的分类中属于——（对目标的）无效性反对也是一个基本反对，目标根本就不会去执行原论证中的方案，即方案等于无效

152. Mouth cancer is adanger for people who rarely brush their teeth. In order to achieve earlydetection of mouth cancer in these individuals, a town’s public healthofficials sent a pamphlet to all town residents, describing how to performweekly self-examinations of the mouth for lumps. 措施目的

Which of the following,if true, is the best criticism of the pamphlet as a method of achievingthe public health officials’ goal?

(A) Many dentaldiseases produce symptoms that cannot be detected in a weekly self-examination.—>并没有特别削弱自检是发现口癌的方法（要点出KW口癌）

(B) Once mouth cancerhas been detected, the effectiveness of treatment can vary from person toperson. —>说明癌症检测出来后的事情，跟自检本身无关

(C) The pamphlet wassent to all town residents, including those individuals who brush their teethregularly. —>只说出发册子的无效，但不能说册子本身不能达目的

(D) Mouth cancer ismuch more common in adults than in children. —>支持发送书面指导的合理性（因为大人识字小孩不识字），不削弱 E

(E) People who rarelybrush their teeth are unlikely to perform a weekly examination of their mouth. —>不刷牙的人也不自检，发的册子白瞎

正确答案E，不过A到底为什么不对啊？这种“措施目的”类型的题——IF措施，THEN目的怎么削弱？
是IF条件根本无法完成？还是说即使IF条件达成了，也达不到THEN的目的？

我是这样理解的：
Many dental diseases 与本题是无关的，我们需要的是Mouth cancer有关的选项，虽然Many dental diseases 不能从weekly -examination中检查出来也无妨，因为这些Many dental diseases 极有可能与cancer没有关联

, describing how to perform weekly self-examinations of the mouth for lumps（肿块）.
这个是小册子教人做的。
A选项没有关系。只要按照小册子教的做了就OK。

题目的前提给出来：Mouth cancer is adanger for people who rarely brush their teeth.

目的：achieve earlydetection of mouth cancer in these individuals.

措施：a town’s public healthofficials sent a pamphlet to all town residents, describing how to performweekly self-examinations of the mouth for lumps.

这题的题目要找一个weaken选项，即要证明该方法不可行。

连接前提和措施目的 -- weaken项使这种对于rarely brush 的人的牙齿具有危害的cancer不能通过上述方法得到早期的诊断。

A选项中的many dental diseases 能代表 mouth cancer吗？且symptom cannot be detected和文章没有直接关系。该项为无关选项。

E选项说对于很少刷牙的人来说，他们不会去关注该种措施 -- 方法不可行，答案。
