试题详情

题目:

Although fullerenes--spherical molecules made entirely of carbon--were first found in the laboratory, they have since been found in nature, formed in fissures of the rare mineral shungite.  Since laboratory synthesis of fullerenes requires distinctive conditions of temperature and pressure, this discovery should give geologists a test case for evaluating hypotheses about the state of the Earth's crust at the time these naturally occurring fullerenes were formed.
 
Which of the following, if true, most seriously undermines the argument?

选项:

A、Confirming that the shungite genuinely contained fullerenes took careful experimentation.
B、Some fullerenes have also been found on the remains of a small meteorite that collided with a spacecraft.
C、The mineral shungite itself contains large amounts of carbon, from which the fullerenes apparently formed.
D、The naturally occurring fullerenes are arranged in a previously unknown crystalline structure.
E、Shungite itself is formed only under distinctive conditions.

答案:

D

提问:

请问这道题,需要看哪一句话来判断选项?因为这道题只有两句话。如果是最后一句话,我的理解:因为试验造fullerenes需要特定的温度和压力,所以这个发现(我觉得指特定的温度和压力)必须可以让地理学家评估当fullerenes形成时地壳的特征。

提问:

请教英吉老师,为什么选D,属于哪一种驳斥呢?(我当时觉得D的角度不对,D只是在讲natural form的构成成分,而原文讲的是其生成的环境)

提问:

想选择B。对题目的理解是因为实验室合成条件严苛所以自然界中也能形成的F物质让科学家想要去研究地球crust的情况。选B的原因是这个物质是也在meteorite上发现,那么found in nature的那些也可能来自外太空(就没必要去检测crust了,因为不在地球上形成)不选D的原因是科学家已经准备检测crust了,不就是默认这个东西是在crust附近形成?(那个structure也可能只是crust的一部分吧)还是说因为是一个未知的structure所以weaken了检测crust的必要?这个题做错了反映的是什么样的思维误区呢?谢谢老师

提问:

今天做题时,碰到两道难题,问题都是对argument进行驳斥,因此直接回原文找结论。ID2947的结论是科学家预测the earth's crust at the time these naturally occurring fullerenes were formed. 所以关注选项 跟怎么形成有关的。排除AB,生下CDE. E有only 排除。最后比较 C D。 ID2948的结论是因为cost的多,所以不好。我就去找跟成本有关,钱有关的选项,所以排除ABD,去比较CE。E说的是成本增加的更快了,跟文章无关,所以排除。 老师这个方法有可行性么?还是因为碰巧?
