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? 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. 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. 这题的答案是b，但是，我觉得d说，在经过这个病後，无法产生抗体的mice 没得角膜炎，不是比较能支持它的假设吗??? 谢谢^^ --
