OG11-14

14.
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）People will follow medical advice when they are
convinced that it is effective.

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

文章说克服susceptibility的方法被发现后，人就不会sick了，所以答案需要把susceptibility和sick搭桥，而不是particular disease和sick,c选项说所有的疾病都是部分的因为susceptibility，所以作者说的克服susceptibility的方法被发现后，当然人就不会生病了（注意这里当然知识必要条件，而不是充分条件，但此选项取非后肯定会削弱原文的结论）

c说所有疾病都是部分因为susceptibility,那就是说还有其他原因导致疾病. 所以不能推出people follow the strategy will never get sick 吧?

提干中最后一句话:people will never get sick.

C.all human sickness......     all 对应 never；

D. ......to some diseases.      some与never不符.

所以选C. C 中的in part 是指所有的疾病都部分（多多少少）是基因缺陷的结果。我同意LZ在第3楼说的意见。
