A rare disease, malicitis, is being diagnosed with increasing frequency. The number of cases reported this year is more than double the number reported four years ago. The government should now allocate more funds for treatment and prevention of malicitis.

All of the following, if true, would weaken the conclusion except

A. funds already available for research in malicitis are currently under-utilized
B. a new test employed for the first time this year detects malicitis at a considerably earlier stage in the development of the disease
C. the number of cases reported this year represents the same fraction of the population as reported in all of the last five years
D. a committee of experts reviewed the funding four years ago
E. a private foundation has committed sufficient funds to cover treatment and prevention needs as well as research for the next five years









OA 是D 谁能告诉我C为什么错？

多谢各位帮助！

是说 现在这些人 是过去5年人的总和 所以患者其实没有增加  因果关系的话 说明 削弱原因 可以理解成 有果无 ...

fraction 不是指 （现在生病的人比上总人口比例）等于（过去五年间每年生病人口比上总人口的比例）吗？
题干中说The number of cases reported this year is more than double the number reported four years ago，那么生病人口的sheer number 增加了，政府多花钱也就justified了.

不明白啊

以下言论纯属个人看法，我觉得这道题逻辑链是这样的，该疾病的increasing frequency发生率增加了，所以政府 ...

我理解你的意思，但是我的理解是生病人数的绝对值增加了，政府是不是就应该allocate more funds呢？

我是不是不应该使用常识逻辑？

本题题干简单粗暴的逻辑链：
某罕见病的发病案例人数越来越频繁，今年的案例人数是四年前的两倍了。→所以 ...

谢谢指点。
那么D如果攻击了Flaw，那岂不是也weaken argument了。
