Critical Reasoning

试题详情

题目:

Humans get Lyme disease from infected ticks. Ticks get infected by feeding on animals with Lyme disease, but the ease of transmission from host animal to tick varies. With most species of host animal, transmission of Lyme disease to ticks is extremely rare, but white-footed mice are an exception, readily passing Lyme disease to ticks. And white-footed mouse populations greatly expand, becoming the main food source for ticks, in areas where biodiversity is in decline.

The information in the passage most strongly supports which of the following?

选项:

A、In areas where many humans are infected with Lyme disease, the proportion of ticks infected with Lyme disease is especially high.
B、Very few animals that live in areas where there are no white-footed mice are infected with Lyme disease.
C、Humans are less at risk of contracting Lyme disease in areas where biodiversity is high.
D、Ticks feed on white-footed mice only when other host species are not available to them.
E、The greater the biodiversity of an area, the more likely any given host animal in that area is to pass Lyme disease to ticks.

答案:

C

提问:

想问一下唐老师,这道题题干说“白脚老鼠的数量在biodiversity下降的地方快速增长,白脚老鼠正在变成ticks的食物” 老师可以具体说一下每个选项的重心都在哪里吗?感觉不知道选什么

提问:

通过最后一句判断在说:老鼠数量增长,变成t的主要食物,当b下降的时候。所以看选项排除了abc,在d和e里纠结了会,看到d在说t啥时候吃老鼠,所以选了e。正确答案是c,不清楚咋匹配出来的

提问:

想选A 原文说人们有L疾病是因为被感染的tick 。 然后被感染的tick是由于吃了带L疾病的动物。 所以能归纳出A 当人们感染L疾病时,被L感染的tick相对较多。 请老师解答

提问:

请问老师: 1、选项A 逻辑哪里有问题 2、选项C内容是否太国绝对(only),原文中只是提到说,在生物多样性下降的地区,白老鼠大量扩张并成为Tick的主要食物来源。并没有说只有当其他食物来源都没有的时候,才吃白老鼠

提问:

我的逻辑思维是这样的: 原文中提到“从大多数的宿主,lyme disease传播到ticks是非常少见的,但是白老鼠是个例外。” 可以断定,没有白老鼠的地方,lyme disease就很少见. 故B正确。 可是C说的是,一个地方如果生物多样性丰富,那么人少得病。可是原文直说了生物多样性“低”的特点 - 白老鼠多导致ticks传染从而导致人得病。可是没说生物多样性“高”的特点,有一种可能性就是生物多样性高,依然有白老鼠,ticks依然传染,人照样生病,所以把C派出了。
