Farmer:Several people in the past few years have claimed to have seen a mountain lionin the suburban outskirts—the latest just last month—and, while mountain lionswere thought to have been driven from this entire region about twenty yearsago, there is no reason for the people who reported seeing a mountain lion tohave deliberately concocted a false report. Therefore, local wildlife managersshould begin to urgently address the mountain lion's presence.
Whichof the following would, if true, most seriously weaken the farmer's argument?
A. Farmers in the suburban outskirts mostly raisecattle and hogs, which when fully grown are generally not attacked by mountainlions.
B. Mountain lions are dissimilar in size andcolor to other wild animals found near the suburban outskirts.
C. No person who claimed to have seen a mountainlion had anyone else with them at the purported sighting.
D. There have been no regional reports in thepast year of mountain lions migrating to the area. E. Recent surveys show that more than half of thepeople in the region report that they have never seen a mountain lion before.
这道题的逻辑链是：有人举报→（山狮一定存在）→需要采取措施
我想请问C项，既然题目里说了没有人会故意提交假的报告，但是C项不是暗示了就是有人故意提交假的报告吗？这样不就是attack Premise？为什么C选项还正确呢？当初也是因为这个原因直接排除了C。以下是我对其他选项的分析~
A. 与逻辑链无关
B. 山狮和其他动物不一样，暗示居民不可能看错，加强逻辑链
D. 没有山狮往这个地区迁徙的报告（我最后选了D....) 没有山狮往这个地方迁徙，代表实际上山狮并不存在？说明村名的报告不可信？
E. 有一些人举报见过山狮，另外这些人报告从来没有见过。和到底存不存在没有关系
