In this task, you will be shown an extract from a movie plot. You need to read the extract and create questions that can be answered from the extract. Once you create a question you also need to provide the correct answer for it. Write your answer like "Question: your question, Answer: your answer". The questions should be well-formed and grammatically correct. The questions should be completely answerable from the given passage and should not require any external knowledge. Subjective questions are not allowed. Short answers containing words that are present in the passage are preferred. Create questions that result in factoid answers. A simple rule of thumb to decide whether a question is a factoid or not is to see if two different people with average reading/comprehension skills would come up with the same answer after reading the passage.
Q: The film follows the novel in presenting a first-person narrative from the point of view of Billy Pilgrim (Sacks), who becomes "unstuck in time" and experiences the events of his life in a seemingly random order, including a period spent on the alien planet of Tralfamadore. Particular emphasis is placed on his experiences during World War II, including the bombing of Dresden in World War II, as well as time spent with fellow prisoners of war Edgar Derby (Roche) and the psychopathic Paul Lazzaro (Leibman). His life as a husband to Valencia (Gans), and father to Barbara (Near) and Robert (King) are also depicted, as they live and sometimes even enjoy their life of affluence in Ilium, New York. A "sink-or-swim" scene with Pilgrim's father is also featured. The scenes of extraterrestrial life on Tralfamadore feature Hollywood starlet Montana Wildhack (Perrine).
A:
Question: What are the names of Billy's children?, Answer: Barbara and Robert.
