LG Game 2 Question 8 Explanation, by LSATHacks
For this question, if you have leather you also have power windows. This tells us two things. Z has power windows, and T doesn’t have leather, because it has no space to also have power windows. Here’s the local diagram:
For A, T can have power windows. The only thing T can’t have is L, because that would force T to have P as well.
B can be true. The only thing T can’t have is L, because that would force T to have P as well.
C could be true. Z, X, W and V have power windows and T could have a sunroof.
D has to be true, since every car with L needs P.
E can’t be true. The fact that Z has L tells us that Z also needs to have P instead of S for its second feature. E is CORRECT.
Wondering if you did in fact draw these local diagrams for each question as they are here. It’s just that it seems that this diagram is larger than most and it eats up time. Do you think this time is saved in the long run by drawing the locals in this instance?
I expect I did. It would probably take 10-12 seconds to reproduce that if you know the rules and have practiced fast drawing. And then you know *everything*. I draw it right beside the questions, and then there’s very fast feedback.
The ones I don’t draw are where I write something like “this diagram disproves E”. I mean, I might have drawn it if I found E challenging for some reason, or wasn’t sure about the question, but often those are just for explanation purposes.
But if there’s just one diagram, and it flows from the rules, I almost certainly drew it.
