#1: E is wrong because Jaclyn and Lorena can't be together onstage period.
The answer is C because Felipe is off stage and so Jaclyn must be off stage, but Lorena can be onstage and because of the rules that says any female = Grant onstage, that answer flies.
#2: The answer choice is D because Keiko cannot be the only woman on the stage at any time.
If she is the only woman on stage, that means Lorena is off stage, and if Lorena is off stage, that means Jaclyn is on. Contradiction.
#4: This question you have to sort of think about it visually. More women than men. That means either 3 (F) and 2 (M) or 2 (F) and 1 (M).
Let's start by doing the first. Can we have All 3 Fs together at once? Well, the answer is no because J and L can't be on stage at the same time.
What about the second equation? Well, two females. Could be K and J and G from the male side. Does that work? Sure. So, the answer is 3: 2+1. C.
#5: Either J or L must be on stage during a show. So that's already one. If J is out, then L must be in because if L is out it mandates that J is in.
If L is out, then J must be in just because the rule says so. Again, this is ONE already. Then, regardless if it's J or L that's on stage, G joins in as well.
That's TWO. That's the answer. C.
I think most of your mistakes are coming from a misunderstanding of the J and L rule, which is good news.
I think this is a case where doing the contrapositive actually hurts you. I got by with just the actual rules, and it was less clutter (and as a result less confusion).
Sorry I can't help with the last game, that was one I couldn't handle. I've done it like three times and for some reason I can't manage to get all the questions right each go. But hey, good luck!
