In response to viral infection, the immune systems of mice typically produce antibodies that destroy the virus by binding toproteins on its surface . Mice infected with the 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 the herpesvirus.
Which of the following, if true, most helps to support the scientists' reasoning?
(Al Other types of virus have surface proteins that closely resemble proteins found in various organs of mice. (Bl Mice that are infected with the herpesvirus but do not develop keratitis produce as many antibodies as infected micethat do develop keratitis. (Cl Mice infected with a new strain of the herpesvirus that has different surface proteins did not develop keratitis. (Dl Mice that have never been infected with the herpesvirus can sometimes develop keratitis. (El There are mice that are unable to form antibodies in response to herpes infections, and these mice contract herpesat roughly the same rate as other mice
答案是C
以下是我做题后整理的思路， 希望大神们可以指导一下是否正确:
question type: support the argument
logic chain: resemblace between proteins on the surface in the eye part (affected by K) and proteins on the H[size=13.333333015441895px]erpesvirus surface --> antibodites to H cause K
[size=13.333333015441895px]premise: antibodies destroy proteins on virus; infection with H -> K
[size=13.333333015441895px]prediction: 排除他因； 情况相反， 结论相反
[size=13.333333015441895px]
A. other type of virus ..have resemble proteins... 类比推理， 但不支持结论[size=13.333333015441895px]antibodites to H cause K ， 无关选项
B 表明无论有没有K， 都会产生antibodies 削弱了 antibodies 和 L 关系， 排除
C. new of H , no K -> no similarity , no K ->情况相反，结论相反 ->支持原结论
D never infected with H , develop K weaken前提，weaken结论
E infection with H ， no antibodies; contract H .. rate 无关选项，不支持结论， 排除
选C
希望大家能相互讨论，共同进步， 谢谢~ 或者谁又更快的思路可以分享吗？
