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?

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.
