I'm struggling a bit on one aspect of the LR questions. Whenever we have an irrelevant answer choice such as B, is that answer choice often good enough to represent the weakest/strongest argument for our question? I've found that the irrelevant answer choices in LR are so hard to predict in whether they will be correct or not.

A would be the only correct answer choice because the ONLY way the medieval Arabs could know that the Homeric epics were untranslatable was IF they had some of those Greek manuscripts in their possession.

This is a great idea

What time zone was the meeting in?
