Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Twenty-year-old Will Hunting of South Boston is a self-taught, genius-level intellect, though he works as a janitor at the Massachusetts Institute of Technology and spends his free time drinking with his friends, Chuckie (Ben Affleck), Billy (Cole Hauser) and Morgan (Casey Affleck). When Professor Gerald Lambeau (Stellan Skarsgard) posts a difficult mathematics problem as a challenge for his graduate students, Will solves the problem anonymously, stunning both the graduate students and Lambeau himself. As a challenge to the unknown genius, Lambeau posts an even more difficult problem. Lambeau chances upon Will solving the problem but Will flees the scene. That night at a bar, Will meets Skylar (Minnie Driver), a British student about to graduate from Harvard, who plans on attending medical school at Stanford and gives Will her phone number before leaving.
Solution: Question: How old is Will Hunting in the movie ?, Answer: Twenty years
Reason: This is a good question which results in a factoid answer, and the answer is correct too.

Now, solve this instance: In 1941, a Capelis XC-12 transport aircraft flown by pilot James "Mac" McCarthy (Dick Purcell) flying between Cuba and Puerto Rico runs low on fuel and is blown off course by a storm. McCarthy, unable to pick up any radio transmissions over the Caribbean, hears by a faint radio signal. After crash-landing on a remote island, his passenger Bill Summers (John Archer) and his black manservant/valet, Jefferson Jackson (Mantan Moreland) take refuge in a mansion owned by Dr. Miklos Sangre (Henry Victor} and his wife Alyce (Patricia Stacey).The quick-witted yet easily frightened manservant soon becomes convinced the mansion is haunted by zombies, and confirms this with some of the doctor's hired help. With the help of Barbara Winslow (Joan Woodbury), the stranded group begins to find out what mysterious events are taking place in the mansion.Exploring, the group stumbles upon a voodoo ritual in the cellar. It is being conducted by the doctor, who is in reality a foreign spy, trying to acquire war intelligence from a captured US Admiral whose aircraft had crashed in a similar fashion on the island. McCarthy comes under the doctor's spell but Summers comes to his aid. Information is being transmitted to Barbara, but Summers stops the ritual. The interruption causes the zombies to turn on their master. Sangre shoots the pilot but falls into a firepit and dies. With Sangre dead, all the zombies are released from the doctor's spell.
