I think I put that caffeine may be the cause of smoking?
A logical answer would involve "fails to consider that the tendency to drink caffeine and higher risk of heart disease could be caused by a common factor". This would still be incorrect, though. The author did in fact consider that possibility, since smoking is the common factor. It's the basis of the argument, actually.
I got this wrong. I chose "similar behavior could cause both smoking and ceffeine consumption" I can't defend this answer for the life of me.
