Red blood cells in which themalarial-fever parasite resides are eliminated from a person's body after 120 days. Because the parasite cannot travel to a newgeneration of red blood cells, any fever that develops in a person more than 120 days after that person has moved to a malaria-freeregion is not due to the malarial parasite.
Whichof the following, if true, most seriously weakens the conclusion above?
(A)       The fever caused by the malarial parasite mayresemble the fever caused by flu viruses.
(B)        The anopheles mosquito, which is the principalinsect carrier of the malarial parasite, has been eradicated in many parts of the world.
(C)  Many malarial symptoms otherthan the fever, which can be suppressed with antimalarial medication, can reappear within 120 days after the medication isdiscontinued.
(D)  In some cases, the parasitethat causes malarial fever travels to cells of the spleen, which are less frequently eliminated from a person's body than arered blood cells.
(E)   In any region infested withmalaria-carrying mosquitoes, there are individuals who appear to be immune to malaria.
E是正确的，但A也没错啊。。。
OG解释A：The issue is not about a similarity of symptoms butabout where the parasites reside.
也有可能是malarial-fever parasite引起其他疾病，引进其他病毒啊，望指点。。。

(1) 寄生虫 （Parasite）寄居的红血细胞120天后被消灭了。 这个寄生虫又不能转移到新的红细胞。
（2）120天后这个人到没有痢疾malaria 的地方发烧了。
结论： 这个人的发烧不可能是由（痢疾）寄生虫引起的。
D攻击： 引起痢疾的寄生虫藏到了一个不可能被消灭掉的地方。 所以即使120天后发烧还是有可能被这种寄生虫引起。

想问一下C为什么错呢？D正确的理由我接受。但是C错误的理由我不明白。og给出的解释是原文没有给出当一个病患搬到malaria-free area 120天后，停止用药与症状复发之间的关系假定。照这样说的话，D原文也没说啊，还不是推测出来的。为什么C就不能当是推测出来的呢。

?这题想问问,C中OG解释点是否有错误..我觉得主要点应该是 题目讨论fever 但是C中说other than fever

因为如果不考虑是不是fever

125天前得了这玩意,第五天搬到free的地方来,此间持续用药,用到第25天,那么第126天(126-27=101 在120天之内)时候复发,这时候已经是入free的第121天了..但仍然和mp有关..望解答

选择d 主要是为了削弱论点中的“由于被热病病菌感染的红血球在120天之后将会新城代谢，因此120天后发烧与感染热病无关”，所以削弱概论点应当尝试找到120天后发烧与感染热病有关，则此时应当尝试去找由它因引起的感染热病，从而导致发烧，选项d 证实位置不同，但是同样引发热病因而确定答案。

A.The fever caused by the malarial parasite may resemble the fever caused by flu viruses.

A明显引进了无关选项, 它让你削弱的点是被感染的红血球的消失, 和发烧的关系. 注意它明确指出是要削弱conclusion.所以A应该首先被排除.CR里有很多这样的,不能直接削弱的答案,要注意.

希望各位大牛指正

不大明白A为什么是无关的？

靠，我说呢。我以为楼主说答案是E是书上得答案呢！害得我还钻研了一堆歪理！！！！：）
现在有毛病，经常过分分析一个本来简单的题

D is the answer!!!
