Task: Question Generation
Input (English): Passage: Six friends, Christian, Elizabeth, Piper, Kate, Adam, and Benjamin, play a game which consists of "yes" and "no" questions that are to be answered anonymously. Once the cards are shuffled, the questions are read aloud and answered by another participant of the game. The questions are deeply personal, covering topics such as sex and incest. Some of the questions posed included "would you sleep with a relative?" and "would you have sex with a minor?"
A year later, the group all meet again at Christian's and Elizabeth's new mansion for a New Year's Eve dinner. The night goes well until the electricity powers out and a package arrives at the door containing six cards; written on them are the words, "prostitute, infidel, homosexual, rapist and hypocrite". These words are associated with the questions that were posed during the Taboo game that they played the previous year.
Horrified by the package, Elizabeth decides to get more wine to alleviate everyone's concerns. Adam, whose question was, "would you have sex with a minor", follows Elizabeth to the wine cellar and accuses her of arranging the delivery of the package. Elizabeth runs upstairs and tells her friends that she was attacked by Adam. When Christian and Elizabeth go back to the cellar, they find Adam with a knife to lodged in his stomach and the word "rapist" attached to the knife which was used to stab him
The couple joins the rest of the group downstairs. Piper, in her drunken state, brings up Christian's father's past affair with a prostitute. Once he impregnates her, he vanishes after his family discovers his infidelity. Piper then questions Benjamin's sexuality. He reveals that he is dating Kate to show his parents that he is not gay in order to keep his inheritance. Shortly after, as Elizabeth and Christian go to a room to speak privately, they discover Benjamin in their bathtub, killed via electrocution with the "homosexual" card beside the tub.
Output (English): What is the name of the person whose father vanished?
