单选题 Within 20 years it will probably be possible to identify the genetic susceptibility an individual may have toward any particular disease. Eventually, effective strategies will be discovered to counteract each such susceptibility. Once these effective strategies are found, therefore, .the people who follow them will never get sick.
The argument above is based on which of the following assumptions?

A、 For every disease there is only one strategy that can prevent its occurrence.
B、 In the future, genetics will be the only medical specialty of any importance.
C、 All human sicknesses are in part the result of individuals' genetic susceptibilities.
D、 All humans are genetically susceptible to some diseases.
E、 (E) People will follow medical advice when they are convinced that it is effective.

【正确答案】 C

【答案解析】[解析] (C)中的“all human sickness”与段落中的“any particular disease”相对应，并把段落中的A与B连了起来，因此(C)实现了问题目的；(D)易误选，但(D)中的“all human”与段落里的“the people who follow them”不对应，且为绝对化概念，必错。注意：一般在假设选项中出现only，solely，in part，partly可以忽略，在取非判定时尤其如此，但在段落中出现这四个词要格外关注。
