The question is Laughing at Dr Alexander Murry's presentation. I initially got an upvote, but this was followed by 1 downvote and 4 close votes for "Unclear what you're asking". I have edited between the 3rd and 4th close votes. Please help me improve further, if need be.
The question does not appear to be unclear per my reading of it. The question appears to boil down to "Why are the audience laughing and what/who are they laughing at?" This is a perfectly clear question. I have made some slight formatting changes but that is only to get content inline with the numbered list. It would be better, however, to have a title for your question that better describes what you are asking rather than something a bit generic.
To address why people may have voted to close, though I of course don't speak for them.
It's so long they didn't read it - a TL;DR section can help for this but you've added the "questions" section now which should be better.
The list of potential options is a bit confusing; I agree with it is quite confusing and long but it does give some nice leads and shows you've thought about it yourself so I'd say keep it. - This has been cleared up a bit by bolding the heading.
Overall though this post seems clear and has been improved so it should be reopened.
