[Critical Reasoning]

试题详情

题目:

The ancient Nubians inhabited an area in which typhus occurs, yet surprisingly few of their skeletons show the usual evidence of this disease.  The skeletons do show deposits of tetracycline, an antibiotic produced by a bacterium common in Nubian soil.  This bacterium can flourish on the dried grain used for making two staples of the Nubian diet, beer and bread.  Thus, tetracycline in their food probably explains the low incidence of typhus among ancient Nubians.
 
Which of the following is an assumption on which the argument relies?

选项:

A、Infectious diseases other than typhus to which the ancient Nubians were exposed are unaffected by tetracycline.
B、Tetracycline is not rendered ineffective as an antibiotic by exposure to the processes involved in making bread and beer.
C、Typhus cannot be transmitted by ingesting bread or beer contaminated with the infectious agents of this disease.
D、Bread and beer were the only items in the diet of the ancient Nubians which could have contained tetracycline.
E、Typhus is generally fatal.

答案:

B

提问:

反思: 原文没有怎么读太明白。 就记得结论是说在食物里的tetra 解释了低的ty的事件率对于Nubians来说。问的是假设。 A 说的是除了ty以外 的别的病菌。 无关 B 没太读明白 (好像是说 teracycline在被做成面包和啤酒后对于抵抗typus这种病,仍然不是没有效果的) 然是我做题的时候读了2遍没概念就知己掠过了。 C 选了C,因为C说了ty不能通过被污染的面包和啤酒传染。 D 面包和啤酒是这帮人只吃的东西。 无关。 E ty 致命 无关 经过排除剩下了BC,都说了食物和ty。感觉C好像是堵住了一个possibility的感觉?猜了C。 这种剩下2个选项,一个能读懂,一个读不太懂的情况怎么办。 谢老师!
