求助 GWD-13-Q40:
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.
先说一下我的理解：
premise A:Mice infected with a herpesvirus generally develop keratitispremise B: Mice infected herpesvirus produce antibodies
Conclusion: keratitis are caused by antibodies to herpesvirus
我选了C，
C中的逻辑：Mice infected herpesvirus which don't get keratitis, But it still produce antibodies.
我认为既然不是K导致了A，
根据前提，A和K有关系
那么就是A导致了K
因此强化了论述
请教一下这道题正确的逻辑思路。多谢 |
