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.
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.
Example solution: Question: How old is Will Hunting in the movie ?, Answer: Twenty years
Example explanation: This is a good question which results in a factoid answer, and the answer is correct too.

Problem: Brian Sweeney "Fitzcarraldo" Fitzgerald (Klaus Kinski) is an Irishman living in Iquitos, a small city east of the Andes in the Amazon Basin in Peru in the early part of the 20th century, when the city grew exponentially during the rubber boom. He has an indomitable spirit, but is little more than a dreamer with one major failure already behind him the bankrupted and incomplete Trans-Andean railways. A lover of opera and a great fan of the internationally known Italian tenor Enrico Caruso, he dreams of building an opera house in Iquitos. Numerous Europeans and North African Sephardic Jewish immigrants have settled in the city at this time, bringing their cultures with them. The opera house will require considerable amounts of money, which the booming rubber industry in Peru should yield in profits. The areas in the Amazon Basin known to contain rubber trees have been parceled up by the Peruvian government and are leased to private companies for exploitation.Fitzcarraldo explores entering the rubber business. A helpful rubber baron points out on a map the only remaining unclaimed parcel in the area. He explains that while it is located on the Ucayali River, a major tributary of the Amazon, it is cut off from the Amazon (and access to Atlantic ports) by a lengthy section of rapids. Fitzcarraldo sees that the Pachitea River, another Amazon tributary, comes within several hundred meters of the Ucayali upstream of the parcel.[1] He plans to investigate that.He leases the inaccessible parcel from the government. His paramour, Molly (Claudia Cardinale), a successful brothel owner, funds his purchase of an old steamship (which he christens the SS Molly Aida). After recruiting a crew, he takes off up the Pachitea, the parallel river. This river has dangerous interior areas because of its indigenous people hostile to outsiders. Fitzcarraldo plans to go to the closest point between the two rivers and, with the manpower of impressed natives (who are nearly enslaved by many rubber companies), physically pull his three-story, 320-ton steamer over the muddy 40 hillside across a portage from one river to the next.[2] Using the steamer, he will collect rubber produced on the upper Ucayali and bring it down the Pachitea and the Amazon to market at Atlantic ports.The majority of the ship's crew, at first unaware of Fitzcarraldo's plan, abandon the expedition soon after entering indigenous territory, leaving only the captain, engineer, and cook. Impressed by Fitzcarraldo and his ship, the natives start working for him without fully understanding his goals. After great struggles, they successfully pull the ship over the mountain with a complex system of pulleys, worked by the natives and aided by the ship's engine. When the crew falls asleep after a drunken celebration, the chief of the natives severs the rope securing the ship to the shore. It floats down the river. The chief wanted to appease the river gods, who would otherwise be angered that Fitzcarraldo defied nature by circumventing them.Though the ship traverses the Ucayali rapids without major damage, Fitzcarraldo and his crew are forced to return to Iquitos without any rubber. Despondent, Fitzcarraldo sells the ship back to the rubber baron, but first sends the captain on a last voyage. He returns with the entire cast for the first opera production, including Caruso. The entire city of Iquitos comes to the shore as Fitzcarraldo, standing atop the ship, proudly displays the cast.
Solution: Question: who were used as slaves with the ultimate goal of building the opera house?, Answer: natives
