I can't tell if A has been copied down in a grammatically incorrect fashion that renders it unnecessarily difficult to understand, or if it is deliberately difficult to make sense of.

If any LSATMax admins/tutors are reading this — Answer choice A looks like this for many of us: "finding a claim to be false on the grounds that it would if true have consequences that are false"

Hi all! To answer your question, I actually also got the official prep plus from LSAC and Answer choice A in this prep test is exactly as it is shown "finding a claim to be false on the grounds that it would if true have consequences that are false". It is not copied down wrongly. I hope the above helps!

That is copied down correctly, but when confronted with tough phrasing like we do often see in the lsat, I like to try to bring it to a concrete example. That is, I would imagine a claim whose consequences must be false- maybe that gravity forces it to be the case that the moon is currently crashing into earth. Since the consequence of that claim is clearly false, the claim is false.
