请教陈向东书里的一题

lisony

Tinea is a skin infection caused by certain fungai, A significant fraction of the people who contract tinea have outbreaks of its symptoms again and again. This proves that, for each of these individuals, the original case of tinea was, in fact, never completely cured.

The argument above assumes that a person who has outbreaks of tinea symptons again and again

(A) can never be completely cured of tinea

(B) does not understand what cause tinea

(C) did not get medical treatment for the original case of tinea

(D) did not take steps to avoid contracting tinea

(E) has not been repeatedly infected with tinea

请问这个题目的推理过程是怎么样的。书中的答案是E。怎么想也想不通。哪位大仙帮忙分析一下，多谢了！

这题的conclusion是the original case of tinea was never completely cured.

ABCD选项都是无关的.至于E,是除了结论的这个原因外没有其他因素影响这个病的治疗,要实在不敢确定，可采用取非.
