标题: 请教蓝色语文verbal的一道推理题
In response to viral infection, the immune systems of mice typically produce antibodies that destroy the virus by
binding to proteins on its surface. Mice infected with a herpesvirus generally develop keratitis, a degenerative
disease affecting part of the eye. Since proteins on the surface of cells in this part of the eye closely resemble
those on the herpesvirus surface, scientists hypothesize that these cases of keratitis are caused by antibodies
to herpesvirus.
Which of the following, if true, gives the greatest additional support to the scientists' hypothesis?
(A) Other types of virus have surface proteins that closely resemble proteins found in various organs of mice.
(B) There are mice that are unable to form antibodies in response to herpes infections, and these mice
contract herpes at roughly the same rate as other mice.
(C) Mice that are infected with a herpesvirus but do not develop keratitis produce as many antibodies as
infected mice that do develop keratitis.
(D) There are mice that are unable to form antibodies in response to herpes infections, and these mice
survive these infections without ever developing keratitis.
(E) Mice that have never been infected with a herpesvirus can sometimes develop keratitis.

为什么C不对呢？注射了h可是没得K的产生了与得k的一样的抗体，那不是表面产生k并不是因为抗体的原因吗？

楼主好，我不知道对不对哈，我这道题选D~
我觉得是这样，这个hypothesis理解一下，就变为：

（anti——h）导致k，即（抗体对 h 作用），才能得到 k
也就是说，要想得到k，anti 和 h 两者缺一不可~
而这道题问的是：找出另一个解释，来支持这个hypothesis~
那来看D:There are mice that are unable to form antibodies in response to herpes infections
前半句的意思就是：有k，没有 anti
and these mice survive these infections without ever developing keratitis.
后半句的意思是：得不到k
小菜以为，这种说法就符合了我刚才说的：要想得到k，anti 和 h 两者缺一不可~
所以小菜选D~
按我的思路咱们再看C，大意就是：有h，没有k，老鼠还产生出和....一样多的anti~那这不就anti和h都有了，那k不就应该有了吗？所以C自然是错的~

我觉得如果思路和我一样，那么你就应该选的出来D~
不知道我的分析对不对啊，求楼主确认答案~~~~~~~~~~

D) is the answer. Very simple correlation and causation type of question. A --> B. No A--> No B is a strengthener.

那请问一下大牛，我的分析是对的吗？

我明白了，我发神经的在看C时把support想成是weaken，

On the right track but you added an extra assumption (antibody works against herpes virus). A better way is to say: the antibody binds to the protein target (premise).

The conclusion of the argument is:
antibody causes the K disease.

The strengthener says:
Without the antibody, there is no K disease.

On the right track but you added an extra assumption (antibody works against herpes virus). A better way is to stay: the antibody binds to the protein target (premise).

The conclusion of the argument is:
antibody causes the K disease.

The strengthener says:
Without the antibody, there is no K disease.

原来如此，NN说的真是很准确~

抱拳啦~~~~~

我也选D~你最近逻辑突飞猛进么~

接问一句：为什么scientists 可以hypothesize anti-B 是导致K的原因呢？为什么不是因为Herpesvirus本身导致的呢？题干里的最后一句推理是怎么得来的啊？
