Hello,

I'm trying to understand why answer choice (a) for this question is incorrect.

I chose answer choice A and am struggling to understand why it's wrong. I understand why D is correct, but I can't get comfortable with ruling out A, and I went back and forth between the two for a while before deciding on A. The tutor in this video said that the issue lies with "all relevant respects", saying that we have no relevant connections to an anteater. However, I would think that we are talking in the frame of mammals - "all species that are similar in all relevant respects" = mammals, all of which, except for the anteater, dream. So, facts about one species of animal (spiny anteater, the specific facts being about their brain size) provide confirmation for hypotheses about all species that are similar in all relevant respects (mammals, the hypothesis being the parasitic connection hypothesis) to the particular species in question (again, spiny anteater). Does anyone have any additional thoughts on why this is wrong / other methods of ruling it out?
