@RJEh of course!

Let's diagram the stimulus first:

"If the standards committee has a quorum, then the general assembly will begin at 6:00 P.M. today."

SCQ ==> GAS@6pm
not GAS@6pm ==> not SCQ

"If the awards committee has a quorum, then the general assembly will begin at 7:00 P.M. today."

ACQ ==> GAS@7pm
not GAS@7pm ==> not ACQ

This is a Must Be True question so we are looking for the answer choice that is 100% supported by the information in the stimulus.

Now let's take a look at (E):

"If the standards committee has a quorum, then the awards committee does not have a quorum."

We know that if the standards committee has a quorum, then the general assembly will begin at 6:00 P.M. today.

SCQ ==> GAS@6pm

This will invoke the contrapositive of the second principle because if the general assembly will begin at 6:00 P.M. today that means it WILL NOT begin at 7:00 P.M., which means that the awards committee does not have a quorum.

SCQ ==> GAS@6pm = not GAS@7pm ==> not ACQ

Therefore (E) is 100% supported so (E) must be true and (E) would be the correct answer.

Hope that helps! Please let us know if you have any other questions.
