midsummer1026

Antoine: The alarming fact is that among children aged 19 years and younger, the number taking antipsychotic medicines soared 73 percent in the last four years. That is greater than the increase in the number of adults taking antipsychotic medicines during the same period.

Lucy: But the use of antipsychotic drugs by adults is considered normal at the current rate of 11 adults per 1,000 taking the drugs. In contrast, the number of children on antipsychotic medication last year was 6.6 per 1,000 children.

Lucy’s argument relies on the assumption that ______.

		normal levels of antipsychotic drug use are rarely exceeded.
		the percentage of adults taking antipsychotic medication is always higher than the percentage of children on such medication.
		the use of antipsychotic medication in children is no different from the use of such medications in adults.
		Antoine is not consciously distorting the statistics he presents.
		a rapid increase in the number of children taking antipsychotic drugs generates more fear of random violence by adolescents than does knowledge of the absolute number of children on such medications.

完全get不到点

11 adults per 1,000 is normal
然而在  the number taking antipsychotic medicines soared 73 percent in the last four years 以后 还是只有6.6 per children， 这种情况下，他的意思就是 adults should和 children 一样。

可是在last year和 last four years 出现这种差距是有可能的

题目大致在说：

我不是很同意你说这里没有结论，我们一起讨论一下啊

在你的中文翻译里已经写出了：所以孩子吃药千分之6.6 也是正常的。我觉的这个就是LUCY 的结论。

这题问的lucy 的assumption, 答案的话去找选项取非后，不支持lucy 的结论的就是对的

我又找了一个很类似的题

Roland: The alarming fact is that 90 percent of the people in this country ...

我想答案是B，因为B取非后就是：unemployment is normally concentrated in geographically isolated segments of population.

我理解的就是失业率在某个地区人群里特别高，那么如果是这样的话，随便50个人里有可能1个以上的失业者的理论就是不能成立的，所以削弱了S的argument.

其实还有一个方法，这道题其实也是道paradox题，因为R和S给出的两个facts 是incompatible. 遇到paradox 的话也可以用why one fact is true even though another one is true as well 来解题。

这样的话题目就简化成为啥R和S都对呢？原因就是B
