Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title

Ex Input:
In the Flash tv show from DC in one scene of "Season 7 Episode 7 (@09:25)", Barry Allen gets struck by lightning and suffers from cardiac arrest. He came back to life by getting chest compressions by his daughter Nora Allen.  So my question is..   How a speedster gets affected by lightning?  I mean speedsters are created by lightning bolt according to stories about Flash. And they contain such amount of lightning energy called  speed force in their system. Shouldn't lightning should recharge their  speed force?   Any promising details would be appreciated on my confusion.

Ex Output:
Why does lightning hit affects speedsters?


Ex Input:
In a movie trailer for the new Spider-Man movie coming out soon, they played certain key scenes and showed Spider-Man kicking butt, but the thing that got me is when he landed on a metal crossbeam outside on a construction site with one arm extended out - and with Captain America's shield in his hand.  Tell me, why did I see this?

Ex Output:
Why did I see Spider-Man with Captain America's shield in his hand?


Ex Input:
As we all know, the most exciting part of seeing a movie is the trailers of upcoming movies before the actual film (note, this is coming from an American point of view, I am uncertain if this occurs in theatres everywhere).  However, there doesn't seem to be much of a forethought given to what trailers are shown, besides making sure big movie trailers are shown before other big movies. For instance, the idea of seeing a Dark Knight Rises trailer before Avengers (two different production companies, let alone two rival comic book companies) doesn't seem to make much sense to me.  Is there a strict guideline trailers are released controlled by the MPAA or do the theatres have free run of what to show?

Ex Output:

What factors go into determining what trailers are played before movies?
