[Critical Reasoning]

试题详情

题目:

It is theoretically possible that bacteria developed on Mars early in its history and that some were carried to Earth by a meteorite.  However, strains of bacteria from different planets would probably have substantial differences in protein structure that would persist over time, and no two bacterial strains on Earth are different enough to have arisen on different planets.  So, even if bacteria did arrive on Earth from Mars, they must have died out.
 
The argument is most vulnerable to which of the following criticisms?

选项:

A、It fails to establish whether bacteria actually developed on Mars.
B、It fails to establish how likely it is that Martian bacteria were transported to Earth.
C、It fails to consider whether there were means other than meteorites by which Martian bacteria could have been carried to Earth.
D、It fails to consider whether all bacteria now on Earth could have arisen from transported Martian bacteria.
E、It fails to consider whether there could have been strains of bacteria that originated on Earth and later died out.

答案:

D

提问:

请教张慧雯老师,这题读的晕晕乎乎的,先说说我的理解:来自不同星球的strains of bacteria有不同的蛋白保护结构啥的,没有两个sb绝对不一样以至于能在另一个星球存活。a选项聊的是这个病毒是否是火星来的,聊的是来源问题,b选项聊的是他怎么运输过来的问题,c选项聊的是他有没有通过其他方式运过来的问题,d聊得貌似也是他是不是火星来的问题?感觉和a有点点像的意思,如何区分ad?e聊的是 strains of bacteria是不是来源于地球然后灭绝了。第一次选了e,请老师讲解ade选项和我的理解问题,如果这道题我在考场上就像说的晕晕乎乎的这个程度,如何尽可能的选出正确答案?

提问:

这道题原文最后2句没读懂,所以就蒙了个E, 其实正确答案为D。问:有时遇到读不懂的原文时,想用 相关、无关 杀选项。但每次还是做错,这该怎么办呢。
