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.

(C) The symptoms that Taylor began showing five days before his death were not caused by a lethal dose of arsenic.

(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.

两个代词没读懂，请高人讲解一下吧

这道题是说一些在总统ZT死亡5天前发生的症状表明他的死与A中毒有关。但是现在的减产发现他骨头中的A含量与他同代人骨头中的A含量相当。而且这些A的含量是远远低于那些中毒死亡的受害者（这些受害者服用了一定剂量的毒之后还存活了一天以上）的骨头中残留的A的含量。问支持。

这是我的理解，请问选C的原因是不是因为直接支持最后一句话？因为受害者骨头中的A含量高，而他们服用了一定剂量的毒，所以ZT如果没有服用那么多剂量的毒，自然体内就不会残留那么多的A了。

至于不选A的原因，是因为它直接反对前提吗？
