The statement basically tells us that either A or B is true, so we can infer that if A is false, then B must be true, and also if B is false, then A is true. The order of A and B is actually irrelevant, both answers would be correct:
~MO -> FI ~FI -> MO
Let me know if you have any further questions.

I understand the rules of the Either/Or question now. Is it correct then when diagramming the sufficient condition it should be first? Then the necessary condition follows in the diagram. As I consider Irina's response it's frustrating that I can't go back and change my answer. I understand the answer is explained right away. However, is it possible before the answer is chosen there is a prompt that asks us to before confirming the answer we selected are we sure? I ask this because I inadvertently selected the wrong answer to be accidentally and forgot the rule of negating the sufficient variable. Unless the drills are just for practice and explanation right after that the answer choice is selected and submitted. I make it a habit to look at all answer choices to see why I chose the correct answer as well as, the incorrect choices. I hope my question isn't confusing.

Hi @lamont, we should indeed try to always diagram the sufficient and then the necessary.
As of now I don't think there is a "confirm your answer" option, but the good news is that the drills and flash cards are really just meant for practice. That said, you should definitely watch to make sure you aren't inadvertently selecting answer on real lsat questions.
