Hello! I am reviewing PT 148, and I am a bit confused about why we can make certain assumptions and not others. On question 12 of section 1, I chose A but the correct answer is supposed to be C. After watching the explanation video, I understand that I had to make a couple assumptions in order to land on A. However, if C is correct, wouldn't you have to assume that the wolves prefer to prey on sick moose over healthy moose? The way I read the answer choice was just that the wolves often eat the sick wolves, not that they tend to eat the sick wolves over the healthy wolves. What if the wolves are still preying on more wolves than the diseases would? Thank you in advance for any help you can offer!

Took this PT recently, so we're trying to resolve: how is it possible that these wolves were introduced to reduce the moose herd and prevent destruction of the vegetation, but the moose herd continued to grow? So C is the correct answer to this paradox since if the wolves are only killing those moose that are weakened by disease, and this disease can be spread to other moose, it shows that because the wolves are only eating the disease-inflicted moose there is an increase in the herd. If the disease were able to spread to the other moose, then chances are the herd would have decreased. However, it is not able to spread to the other moose because, well, the wolves only eat the ones with the disease. They can still prey on wolves that are healthy too, but in my opinion, that is an assumption that would not be relevant in helping resolve this paradox, since the answer choice has to give an answer of how the population of moose is still growing which is because the wolves are preying on the moose which are disease inflicted, which could spread to other moose, but is not because they're being eaten; thus, the population is increasing.
Hope this helps a bit!
