I can see now why A is the right answer and understand that the theories and total mass are hard to connect / not related, but the way D is worded can be misleading.

I translated the three first logic sequences right, but struggled to place "Downtown traffic congestion decreases"

It made more sense to place it as the sufficient event for profits to increase. Totally forgot to negate it.

If answer choice D reads: "The author of Passage B is more skeptical of Evolutionary Psychology in general than the author of Passage A is" would that make D the right answer or a better answer than answer choice B?
