Probably just frustrated, but I feel like A is one of those answers where kevin would say "this doesn't actually help, because it's already a reasonable assumption." Like it seems totally obvious to me that A is a reasonable assumption bulit into the stimulus.

Thought a good example for hypothesis 3 would be being raised in a smoking household. Around smokers which my cause you to smoke, and second hand smoke may cause lung cancer. But then maybe it gets confusing if inhaling smoke causes lung cancer then.
