In the explanation for this question, J.Y mentions that there are several other flaw questions where the flaw is that they say that a correlation between A and B, and a correlation between A and C, means that B and C are correlated. The example he uses that's much clearer than what they're using in this question is that there's a correlation between being a motorist and wearing a seatbelt, and there's a correlation between being a motorist and sustaining an injury in a motor vehicle accident, but that does not mean that there is a correlation between wearing a seatbelt and sustaining an injusry in a motor vehicle accident.

Anyway, he said that there are other questions like this one, but never said which ones they are. Does anyone know of others or any ideas on how I'd find more like this? Thanks!

I’ve been studying for the last year or so. My diagnostic was 164. A week ago, I logged a 171 and was psyched. But I took another practice test this week and got a 163. I tend to find in my practice sections that I have two modes: either I get a -0 to -3 OR I go like -5. Has anyone encountered this sort of swinging inconsistency? It’s frustrating and I’m not sure how to fix it more consistently. The annoying thing is that in the last two PTs I mentioned above (171 & 163), both of my scores were 178 & 179 respectively. I’m scratching my head and supposed to take the real thing next week. Any advice or encouraging stories would be greatly appreciated! Thanks!
