PT28.S1.Q23 - Clinical depression

Hello guys,

I have a quick question for y'all concerning two answer choices in this question. I believe it is critical to understand why answers are wrong — especially for "weaken except" questions. In this situation, while I got the right answer, I'm still left to wonder how and why answer choices B and E weaken the argument.
Thanks!

    LFL patterns correlate positively with mood
    So, LFL activity causes mood.

    Task: make it less likely that LFL activity causes changes in mood.

    B - depression causes sleep which lowers LFL activity. This shows that the cause/effect relationship could be reversed.

    E - depression inhibits social interaction, removing a means of stimulating LFL activity. Again, this shows that the relationship could be reversed.

    When presented with a causal claim remember to look for ways to show:

    1. Cause without effect
    2. Effect without cause
    3. New causal factor
    4. Cause/effect is reversed
    5. Problem with the data.

    I think this is a good question. I eliminated most but I listened to JY's explanation.
