标题: 【请教】GWD-T-9-Q14. GWD-13-40

T-9-Q14. GWD-13-40 C D ？？？

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.

C为何不对，not+weaken？？？

请各位大虾指教！！！谢谢！！！

THE SAME QUESTION

作者: lijiahui0422 时间: 2009-7-28 07:57

C. Mice that are infected with a herpesvirus but do not develop keratitis produce as many antibodies as infected mice that do develop keratitis.

我觉得C恰好是削弱了结论，结论是说老鼠得K是由于H病毒引起的antibodies C说被h感染却没有得K和被感染得K的老鼠产生antibiotic一样多，直接说明了antibodies不是导致老鼠得K病的原因，这不削弱了么

Mice produce antibodies when virus is present. These antibodies destroy the virus by binding (attaching) to the protein on the virus surface. When a particular virus is found in mice, the mice always have a disease that affects the eyes. The hypothesis is that the protein of of eye cell is similar to the protein of the virus, the antibodies accidentally bind to the protein of the eye cell and destroy the cell.
When you see too many words unknown to you, be cool. Guess what it might be. Most of the scientific terms are not important at all. For complex sentences, break them down into simple sentences. 并不需要懂那些单词。
TO 1111YYYY，你要MINDFREE兄用中文解释，你不如杀了他吧。
整段话的意思为：对病毒感染做出反应，老鼠通常产生抗体，这种抗体附着到病毒表面的蛋白质，将它杀死。感染H病毒的老鼠通常得K病（一种眼睛病）。因为眼睛的这部分细胞表面的蛋白质和H病毒表面的蛋白质极其项似，所以科学家猜测K病是对H病毒的抗体引起的。
其实这道题你不需知道原文内容便可知答案。答案是个因果型结论，即认为某个原因导致某种现象。它的支持选项通常是1：排出其他原因导致该现像。2。有因有果。3。无因无果。4。因果不倒置。5。提供去推导因果关系的信息是准确的。
具体到该题，答案认为抗体导致K病。D说无抗体的老鼠没得这种病。无因无果。

我尝试来解答一下这道题：
首先问的是support，按照CR Bible,要么加强premise,要么排除其他可能性（本题考得是这个情况）
herpesvirus 简称 heps
keratitis 简称kera
conlclusion: kerat ==> antibodies to heps

Premise1: heps develop kera

Premise2: antibodies destroy by binding to proteins on its surface.

Premise3: proteins on the surface of cells in this part of the eye closely resemble those on the heps surface.

选项C 是削弱
选项D 老鼠没有antibodies的情况下存活了，而且他们也没有kera, 间接说明了antibodies是导致kera的原因。
