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

SOLUTION: Why does the demon that possesses Regan react to the "fake" holy water?

PROBLEM: Does The Shining have a distinct location or is it like Springfield where you can make a good guess but it's never really described?

SOLUTION: Where is The Shining set?

PROBLEM: In the Transformers films the Autobots and Decepticons always change between their humanoid form and (with the exception of Bumblebee's upgrade) the same cars. Assuming that they choose vehicles because they want to blend in on earth, they must be able to transform into a myriad of other mechanical objects (most likely with some size restrictions). Why don't they transform from plane to car to ship and back again as required?

SOLUTION:
Why do the Transformers always transform into the same cars?
