Which of the following, if true, most seriously weakens the conclusion above?

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.


正确答案:D


题目解析:

题意:疟疾发热的寄生虫寄生在红细胞内,红细胞120天后,会从人体内排出,而寄生虫,不能够转移寄生在新的红细胞内,所以120天后,当到达一个没有疟疾的地方时,如果出现发烧,那跟疟疾寄生虫是一点关系都没有了。

问什么观点,反驳了以上的观点。

A,说疟疾发烧和flu发烧的迹象一样。无关
B,有一种蚊子,这种蚊子是疟疾寄生虫的主要携带者,已经被根除了。无关
C,无关,因为题目只让反驳关于发烧的,跟其他symptoms无关
D,疟疾寄生虫会寄生到spleen里去,不会那么容易被排除体外,所以120天后到了疟疾free的地方出现发烧,那还是有可能是因为疟疾。
E,有疟疾携带的蚊子的地方,有些人对疟疾免疫。无关
