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?
The symptoms that Taylor began showing five days before his death are consistent with poisoning other than arsenic poisoning.
Taylor's death was not the result of any kind of poisoning.
The symptoms that Taylor began showing five days before his death were not caused by a lethal dose of arsenic.
The symptoms that Taylor began showing five days before his death grew more severe each day.
It is unusual for a person who has ingested a lethal dose of arsenic to survive for more than a day.
《毕出21套》第6套第5题
题目：ZT死前5天有A毒的症状，但是死后的骨头检查没有检测出异常A毒水平，可以判断ZT不是因为A毒死亡的
A：和文章相反
B：ZT的死可能是某种中毒，但不是A毒
C：ZT的症状不是因为吞噬了致死剂量的A毒导致的，ZT不是因为A毒死亡的，所以ZT不是吞噬了致死剂量的A毒引起了症状
D：文章没有提到
E：文章没有提到
ZT在死亡前5天就表现出了和arsenic中毒一样的症状。
验证后发现，他骨头里毒素含量比服下致死量后存活超过一天的人要低。
a,并没有提到其他中毒症状，没法说明是其他中毒而非arsenic中毒
b,没有提及死因
c,可以说明不是致死量导致的症状 → 剂量比致死量要少，自然导致的症状与致死量导致的症状不同
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.ZT骨头里的毒素的含量对比的就是活着超过1天的受害者的毒素含量---所以E中有可能可以活过1天，举得受害者的例子就是活过1天的。这是演绎推理！！！看清楚题目！！！所以B过于绝对了，文中的论据无法支撑
ZT在临终之前5天所表现出来的症状和 arsenic poisoning一致。最近对ZT遗体的骨头鉴定发现，遗留的毒素含量比起那些吞下致命剂量且活了超过一天的人的骨头内的毒素更低
must be true:
choice c, ZT去世前5天表现出来的症状并不是由致命剂量引起的
E选项不正确是因为范围无关，没有把讨论范围限定在总统身上。原题目的讨论范围是总统和中毒病人，不是普通人。
contemporaries：同时代的人。。。。。
前提是总统死前五天已表现出中毒（只确定毒的种类）症状，若之前已服毒1 lethal dose（致死剂量），活了超过一天以后消化后留在骨头中的量比其他同时代的人的量（也即总统遗骸骨头中的量）要大得多，说明总统并没有服用致死剂量这么多。 要么吃的少，要么还有其他毒药综合作用。E选项本身没错，可能是客观事实，但是不能从文段中推出。总统又活了五天，但有没有服用1 lethal dose（致死剂量）还是个疑问。
不懂E为什么不对
