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.

C又錯在哪裡呢?

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.(題目背景) Mice infected with a herpesvirus generally develop keratitis, a degenerative disease affecting part of the eye. (現象) Since proteins on the surface of cells in this part of the eye closely resemble those on the herpesvirus surface (觀察), scientists hypothesize that these cases of keratitis are caused by antibodies to herpesvirus(推導結論).

Which of the following, if true, gives the greatest additional support to the scientists’ hypothesis?

C.Mice that are infected with a herpesvirus but do not develop keratitis produce as many antibodies as infected mice that do develop keratitis. (無法證明antibodies導致keratitis,因為不論是否develop keratitis,其產生的antibodies數量皆同!!)

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.(加強推導之結論,說明若是mice無法產生antibodies,則不會得到keratitis)E.Mice that have never been infected with a herpesvirus can sometimes develop keratitis.

同學，我認為這兩題的解法都是一樣的思維喔!!!
你可以比較一下，答案就是典型的{無此因，就無果}13-32 http://www.formosamba.com/phpBB3/viewtopic.php?t=1385

iamdior如此說
C.Mice that are infected with a herpesvirus but do not develop keratitis produce as many antibodies as infected mice that do develop keratitis. (無法證明antibodies導致keratitis,因為不論是否develop keratitis,其產生的antibodies數量皆同!!)

C 這樣算是weaken上述的hypothesis 嗎??
因為與文中所推得假設不符的
these cases of keratitis are caused by antibodies to herpesvirus.

(C) 好像傾向弱化: antibiotics 和 keratitis 無絶對的關聯.

分享我的簡單看法：

題意：A-->K-->H
問SUPPORT：
A：A-->K-->產生H以外的東西 與題意不同
B：轉移焦點
C：A-->H，可以不用有K 與題意不同
D：沒有A-->沒有K 正確
E：沒有H也可以有K 與題意不同
