In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Input: Consider Input: Passage: The film is set in the home of a mad scientist called Professor Noodle. Professor Noodle has just developed a rejuvenation solution that reverses the aging process. Stan and Oliver are chimney sweeps and arrive to sweep the chimney. Oliver goes on to the roof and Stan stays below at the fireplace. Stan begins to shove the sweep up the chimney and knocks Oliver backwards and down through the skylight. Oliver comes back on to the roof and begins to pull the sweep up. Stan has hung on to the sweep and arrives at the roof. Oliver drops him back down through the chimney. Stan doesn't have enough extensions for the sweep and decides to use a rifle to shove the sweep the last part of the way. The gun goes off nearly shooting Oliver. Stan decides to go up to the roof and as he opens the skylight he knocks Oliver off the roof and down onto a greenhouse. Hardy finally falls down the chimney dislodging many bricks, sending a cloud of soot all over the living room and onto the butler, and damaging the piano. The butler says something about an electric chair, and stalks out. Stan and Oliver start to clean up the soot around the fireplace. They become distracted and Stan shovels the soot into Oliver's trousers.
Professor Noodle decides to test his rejuvenation solution. He puts a duck in a vat of water and adds a drop of his solution. The duck turns into a duckling. The professor is excited and decides to show Stan and Oliver his discovery. He puts another drop of his solution into the vat and the duckling turns into an egg. Stan and Oliver decide to test the solution for themselves when the professor leaves the room to fetch and rejuvenate the butler. Stan accidentally knocks Oliver and the solution into the vat. Oliver emerges as a chimpanzee. Despite being rejuvenated—de-evolved, even—into a chimp by the massive overdose of the solution, he is able to say what he has said multiple times throughout, "I have nothing to say".

Output: What does the person who became a chimpanzee do for a living?


Input: Consider Input: Passage: In the years following the eruption, despite earning rapid fame and opportunities to research internationally in Japan, New Zealand, and Guadeloupe, Glicken still failed to obtain a job at USGS. Senior employees at the Survey found his behavioral oddities unsettling. Activity at Mount St. Helens diminished, prompting USGS to reduce CVO's budget and contemplate closing the station. He continued helping the Survey until 1989, also serving as an assistant researcher at the University of California at Santa Barbara.From 1989 to 1991, Glicken continued his volcanological studies in Japan as a postdoctoral fellow at the Earthquake Research Institute of the University of Tokyo, supported by grants from the U.S. National Science Foundation. Later, while a research professor and translator at Tokyo Metropolitan University, Glicken became involved with research at Mount Unzen. The volcano had recently resumed eruptive activity in November 1990, after being dormant for 198 years. In the months after its first activity, it erupted sporadically, and the government evacuated its vicinity near the end of May 1991. On June 2, 1991, Glicken visited the mountain with Katia and Maurice Krafft. The three entered a danger zone near the base of the volcano the following day, assuming that any potentially hazardous pyroclastic flows would follow a turn in the landscape and safely bypass them. Later that day, a lava dome collapsed, sending a large flow down the valley at 60 miles per hour (97 km/h). The current reached the turn before separating into two parts, and the upper, hotter part swiftly overcame the volcanologists' post, killing them upon impact. In total, 41 or 42 people died in the incident, including press members who had been watching the volcanologists. The volcano burned down 390 houses, and the remains of the flow extended 2.5 miles (4 km) in length. Glicken's remains were found four days later, and were cremated according to his parents' wishes. To date, Glicken and Johnston are the only American volcanologists known to have been killed by a volcanic eruption.

Output: What is the last name of the American volcanologist that has died along with the man continued his volcanological studies in Japan?


Input: Consider Input: Passage: On the inaccessible island of Soay are sheep of a unique type, which lived as feral animals and belonged to the owner of the islands, not to the islanders.  These Soay sheep are believed to be remnants of the earliest sheep kept in Europe in the Neolithic Era, and are small, short-tailed, usually brown with white bellies, and have naturally moulting fleeces.  About 200 Soay sheep remain on Soay itself, and soon after the evacuation a second feral population of them was established on Hirta, which at that time had no sheep; these now number between 600 and 1,700. A few Soays have been exported to form breeding populations in other parts of the world, where they are valued for their hardiness, small size and unusual appearance. On Hirta and Soay, the sheep prefer the Plantago pastures, which grow well in locations exposed to sea spray and include red fescue (Festuca rubra), sea plantain (Plantago maritima) and sea pink (Armeria maritima).The St Kildans kept up to 2,000 of a different type of sheep on the islands of Hirta and Boreray.  These were a Hebridean variety of the Scottish Dunface, a primitive sheep probably similar to those kept throughout Britain during the Iron Age.  At the time of the evacuation all the islanders' sheep were removed from Hirta, but those on Boreray were left to become feral, and these are now regarded as a breed in their own right, the Boreray.  The Boreray is one of the rarest British sheep, and is one of the few remaining descendants of the Dunface (although some Scottish Blackface blood was introduced in the nineteenth century).


Output: What is the type of sheep that was left during evacuations by the people who had up to 2,000 different types of sheep?
