Task: Question Generation
Input (English): Passage: Fred goes into music class to find his favorite teacher, Mrs. Felson, has been replaced by a teacher named Mr. Devlin. Walking home from school, Fred notices a strange girl named Talia following him. Fred believes he is being stalked, but the girl just walks the same way to school as him. Spying on Devlin that night, Fred sees him burying something, which he suspects is the body of Mrs. Felson. Kevin's mother invites Fred and his mother to a party for Mr. Devlin. At the party, Fred's mother falls in love with Mr. Devlin, and Fred learns that Talia is actually Kevin's sister.
The next day, Fred becomes extremely suspicious of Devlin and reaches the conclusion that he is a vampire. Mr. Devlin takes Fred's mother on a date, so Fred enlists his friend Bertha to spy on them. At a restaurant, Fred and Bertha learn that Mr. Devlin doesn't like garlic on his fries, making them all the more suspicious. Later that night, Fred's imaginary Dad brings him to a wrestling arena, where they tag team against Mr. Devlin and Kevin.
Fred is horrified at school the following day to discover Mr. Devlin running a blood drive at school. He's even more worried to discover Bertha taking personal music lessons from Devlin. Fred gathers items to use as weapons against Devlin, planning to defeat him at the school piano recital. Fred arms himself with him various tools and goes on a shooting spree of garlic sauce at the recital, soaking everyone except Devlin.
