GWD-10-Q19
Which of the following most logically completes the passage?

A certain tropical island received food donations in the form of powdered milk for distribution to its poorest residents, who were thought to be malnourished. Subsequently, the rate of liver cancers among those islanders increased sharply. The donated milk was probably to blame: recent laboratory research on rats has shown that rats briefly exposed to the substances aflatoxin tend to develop liver cancer when fed casein, a milk protein. This result is relevant because       .

A in the tropics, peanuts, a staple of these island residents, support a mold growth that produces aflatoxin.
B  the liver is more sensitive to carcinogens, of which aflatoxin may be one, than most other bodily organs.
C  casein is not the only protein contained in milk.
D  powdered milk is the most appropriate form in which to send milk to a tropical destination.
E  the people who were given the donated milk had been screened for their ability to digest milk.
答案选择 Ａ
我选的　Ｃ

如果我没弄错的　话　，这道题应该问得是相关性吧？？？
纠结　多谢　为啥＝选A呢

红色部分为结论

题干说，收到奶粉的居民的肝癌的几率增加。
做的实验是，接触Protein以及aflatoxin的rats也会得肝癌。

因此，要补出那些收到奶粉的居民有机会接触aflatoxin.

楼主要看清楚实验是干嘛的，实验说的是喝牛奶同时接触A物质导致肺癌，现在大家都喝牛奶了， 当然要证明大家也都接触A了咯~
