The symptoms that United States President Zachary Taylor began showing five days before his death are consistent with arsenic poisoning.Recent examination of Taylor's bones, however, revealed levels of arsenic comparable to those found in the bones of Taylor's contemporaries.These levels are much lower than the levels of arsenic that remain in the bones of arsenic poisoning victims who live for more than a day after ingesting a lethal dose of the poison.

Which of the following is most strongly supported by the statements given?

(A) The symptoms that Taylor began showing five days before his death are consistent with poisoning other than arsenic poisoning.

(B) Taylor's death was not the result of any kind of poisoning.

(D) The symptoms that Taylor began showing five days before his death grew more severe each day.

(E) It is unusual for a person who has ingested a lethal dose of arsenic to survive for more than a day.

为什么选C？

题目是这样的，
ZT死了，在他死的5天前，他身体产生了和砒霜中毒一致的现象（这里只是说现象，当然很多其它中毒也可能产生相同的symptom），但是zt死后身体中的毒量和他同龄人相当（这里是暗示他并没有中毒，假设是他体内毒量本来就和同龄人一样），测得的毒量比被注射砒霜后挣扎了多于一天的那些人体内的毒量低很多。

a.和题目提供的事实矛盾，x
b.根据题目的线索推断不出，，，他当然有可能因为其它中毒死亡
c.显而易见的，如果5天前zt被注射致死量砒霜的话，他也许可以活超过5天，但是，他体内的毒量水平肯定是和那些也被砒霜毒死的人差不多的，而不是低到和一般的活着的同龄人一样。
d完全没关系
e和题目无关推断
