Hi @Maroun, Here's one way to diagram it, which is generally a good approach to take a match the flaw question. I'll diagram the stimulus first. An implicit premise here is that Lester works at Leila's electronics; it would've been better if this had been made explicit, but by the time we get to the answer choices it's pretty obvious. WLE = Work at Leila's electronics RPPE = Receive poor performance evaluation RR = receive raise P1) WLE - > ~(RPPE & RR) We can rewrite this as WLE - > ~RPPE v ~RR P2) ~RR Conclusion: RPPE. To translate what's going on into English, since we know that Lester works at Leila's electronic, he can't have gotten both a poor performance evaluation and a raise. And we know he didn't get a raise, so we conclude that he received a poor performance evaluation. But the problem with this logic is the following: it is completely possible that Lester could not have gotten a raise and not have gotten a poor performance evaluation. Remember that the logical "OR" is inclusive and so both conditions can be true. Even if WLE - > ~RR & ~RPPE, (P1) is still true. The answer choice we're looking for has to match this solution, and after going through them, we can see that (D) commits the same logical fallacy. Diagramming (D), we get P1) Lives in house - > ~(Own & Pay rent) Which we rewrite as Lives in house - > ~Own v ~Pay rent P2) ~Own house Conclusion: Pay rent And we can immediately see that this parallels the structure of the stimulus. Hope this helps! If anything was unclear, feel free to ask further questions.
