Critical Reasoning
试题详情
题目：
Farmer: Several people in the past few years have claimed to have seen a mountain lion in the suburban outskirts—the latest just last month—and, while mountain lions were thought to have been driven from this entire region about twenty years ago, there is no reason for the people who reported seeing a mountain lion to have deliberately concocted a false report. Therefore, local wildlife managers should begin to urgently address the mountain lion's presence.
Which of the following would, if true, most seriously weaken the farmer's argument?
选项:
A、Farmers in the suburban outskirts mostly raise cattle and hogs, which when fully grown are generally not attacked by mountain lions.
B、Mountain lions are dissimilar in size and color to other wild animals found near the suburban outskirts.
C、No person who claimed to have seen a mountain lion had anyone else with them at the purported sighting.
D、There have been no regional reports in the past year of mountain lions migrating to the area.
E、Recent surveys show that more than half of the people in the region report that they have never seen a mountain lion before.
答案:
C
提问：
老师这道题我选到了B选项；一下是我的分析：
背景：好几个人在郊区看到了山地老虎，最近的一次是近几个月；背景2：多年前曾经发现过老虎；论点：人们没有理由说谎；结论：应该开始寻找老虎 题目要求：削弱
正确答案：C；我选了B
C选项强调的应该是没有人是和其他人一起看到老虎的，所以没有证人
这个题我不太明白的点在于，C选项看上去有点驳斥原文给出的背景知识啊，题目说了不会说谎来着；我选择B的原因是郊区有和狮子非常类似的其他野生动物，所以有可能搞错。

提问：
这道题留下了C, D, E中错选了E。原文的意思是有人看见了狮子，这个狮子是起源于本地，人们所报告的是没错的。所以，当地人应该强调狮子的出现。D选项读出来的意思是过去没有报告显示这个狮子的出现，因为时间点不同，所以排除了。E读出来的意思是在最近的调查中，超过一半的人都没有看见过狮子。所以C和E相比，C好在哪里？E有什么逻辑错误。谢谢
