Red blood cells in which the malarial-fever parasite resides are eliminated from a person's body after 120 days. Because the parasite cannot travel to a new generation of red blood cells, any fever that develops in a person more than 120 days after that person has
moved to a malaria-free region is not due to the malarial parasite.
Which of the following, if true, most seriously weakens the conclusion above?
(A) The fever caused by the malarial parasite may resemble the fever caused by flu viruses.
(B) The anopheles mosquito, which is the principal insect carrier of the malarial parasite, has been eradicated in many parts of the world.
(C) Many malarial symptoms other than the fever, which can be suppressed with antimalarial medication, can reappear within 120 days after the medication is discontinued.
(D) In some cases, the parasite that causes malarial fever travels to cells of the spleen, which are less frequently eliminated from a person's body than are red blood cells.
(E) In any region infested with malaria-carrying mosquitoes, there are individuals who appear to be immune to malaria.
题目分析：原文比较简单，就不带着各位读了，A说这种寄生虫导致的发烧和流感病毒导致的发烧很相似，没提过这两种病毒的比较，杀。B说携带这种病毒的蚊子在世界的大多数地方都消灭了，没说，杀。C说除了fever其他症状，范围和原文没任何关系了，杀。D这种病毒转移到别的地方了，原文说这种寄生虫寄居在红细胞里，红细胞没了寄生虫也就没了，可是这个选项说寄生虫跑到别的地方了，可以驳斥，留着。E说有人对于这种病是免疫的，没提过，杀。
