"Which one of the following, if substituted for the condition that" shortcut

Hey everyone, quick shortcut for these kinds of LG questions. First, look at each of the answer choices and see if any of them must be true. The ones that aren't are instantly wrong. Think about it--you're testing for logical equivalence. For two statements to be logically equivalent, they must be true in all circumstances. If either one of the statements isn't true all of the time, they can't constitute a logically valid premise, and they can't be used to imply the validity of other statements.
Hope this helps!
