B vs D

@Milo-Hammer, (B) tells us that that the author of A is more committed to the principles of evolutionary psychology than the author of B. This is accurate - A attempts to justify altruism using the principles of evolutionary psychology, but we cannot infer that B is committed to these principles at all. On the contrary, B right off the bat says "evolutionary psychology is a kind of conspiracy theory..." (D) tells us that the author of B is more skeptical of evolutionary theory in general than the author of A. This is incorrect - both authors discuss evolutionary psychology, not evolutionary THEORY in general. We cannot infer that just because the author of B is skeptical of evolutionary psychology, he is skeptical of the concept of evolution/ natural selection as a whole. Does this make sense? Let me know if you have any further questions.
