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 Exorcist, why does the demon that possesses Regan react to the “fake” holy water sprinkled by Father Karras?  It's hard to believe that the demon mistakes the tap water for water blessed by a priest. It certainly makes the entity that much less frightening.

Ex Output:
Why does the demon that possesses Regan react to the “fake” holy water?


Ex Input:
In Flash season 4 episode 18 (Lose Yourself) Devoe attack star labs and take the powers of all bus metas. He even takes away the power of Killer Frost. He could easily take the power away from Barry as he was laying on the floor or he could absorb his power too. Same in the case for Cisco.  So why didnt Devoe takes Flash's power?  Is it because Devoe can only absorb the powers of the bus metas?

Ex Output:
Why didn't Devoe take Barry's power?


Ex Input:
This question has been bugging me for a while. Maybe it is a bit overthought.  Does Nick Fury really need to send a pager message to Captain Marvel after Thanos' snap? I mean, there is only a 50% chance that Captain Marvel would survive, and if she does, she will come to know what had happened. If she cares about Earthlings, she would naturally come here for help.   So, was all this pager thing unnecessary?

Ex Output:

Was the pager message from Nick Fury to Captain Marvel unnecessary?
