I understand why it's D and not C, but it required a lot of thinking and was not formulaic - I don't think I could get this answer quickly under time pressure consistently. Is there a rule of thumb that helps us eliminate C in scenarios like this? "Be careful with 'most' relationships when kicking something up to the domain"?

22/25 first try. Easier than I expected!

So far, the questions have been too easy. I'm not sure if that's just because I'm still in the early portion of the core curriculum, but it might be good to have some more challenging questions.

Flawed premise, because eliminating four wrong answers does not automatically give you the correct answer. You can eliminate the four wrong answers AND eliminate the correct answer, and you have still eliminated the four wrong answers but will get the question wrong because you have also eliminated the correct one. So, if you accidentally eliminate the correct answer you can get the question wrong while only making one mistake. Should say: eliminate the four wrong answers and ONLY the four wrong answers.

When are you taking the test?

D almost fucking got me on this one. Good try, LSAT!
