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. 选c作者: zzzyyyy 时间: 2012-8-20 23:15

C选项里面说的内容没有出原文的范围 除了C其他选项都出了范围 都能排除 至于C为什么是对的 原文最后一句说 要是是caused by a lethal dose of arsenic并且活了超过1天的话那arsenic的level不可能会像从T的bones里面检查出来的arsenic的level那样低 所以他的症状肯定不是caused by a lethal dose of arsenic
