I'm having a hard time understanding this question at all. I've found very little help online for this question. Can anyone please explain.

Thank you everyone for the help. That definitely clarifies a lot.
I think the key to really understand this question lies in the wording "the general assembly." This implies that there is one general assembly.
A - D are all pretty cookie cutter flawed argument types.
E:
If the SC has a quorum, then the party is at 6.
By the laws of time (and based on every sci-fi movie, you can't mess with the laws of time) [If the party is at 6, then the party is not at 7.]
Contrapositive of 2nd sentence: If the part is not at 7, then the AC doesn't have a quorum.
Push those together: If the SC has a quorum, the AC doesn't have a quorum.
[Stimulus]
・Standards Committee Quorum → General Assembly 6PM
・Awards Committee Quorum → General Assembly 7PM
Common sense assumption:
General Assembly starting at 6PM means that it can’t start at 7pm.
Standards Committee Quorum → General Assembly 6PM → /(General Assembly 7PM) → /(Awards Committee Quorum)
(E): Standards Committee Quorum → /(Awards Committee Quorum)
The question talks about 2 distinct committees, and if one committee has a quorum that is sufficient to guarantee the general assembly will start at a specific time (6 for 1, 7 for the other). The incorrect answer choices include 2 fake contrapositives that try to link failing the necessary condition for one committee having a quorum to the other committee, almost like an "either the GA starts at 6 or the GA starts at 7 rule" (ACs A and D). That is not what the stimulus states. It does not say the GA has to start at a specific time, or at all. AC B is also hoping that the reader will assume that either one committee or the other will have a quorum. AC C is a simple sufficiency/necessity confusion (just because the GA starts at 6 doesn't guarantee the committee had a forum.
Finally, E is the correct answer because it acknowledges that the GA cannot begin at 2 different times. One way they could have phrased the correct answer choice is by running the contrapositive of one of the if/then statements given in the stimulus (something like if the GA starts at 5:59, the standards committee did not have a quorum). They choose to say that both sufficient conditions cannot be satisfied because the resulting necessary conditions contradict each other. Hence, if one committee has a quorum, the other does not.
