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.

[Q]: 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 rejuvenatedde-evolved, eveninto 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".
[A]: What does the person who became a chimpanzee do for a living?

[Q]: Passage: Geologically, Portland is separated into two areas; the steeply sloping land at its north end called Underhill, and the larger, gently sloping land to the south, called Tophill. Portland stone lies under Tophill; the strata decline at a shallow angle of around 1.5 degrees, from a height of 151 metres (495 ft) near the Verne in the north, to just above sea level at Portland Bill. The geology of Underhill is different to Tophill; Underhill lies on a steep escarpment composed of Portland Sand, lying above a thicker layer of Kimmeridge Clay, which extends to Chesil Beach and Portland Harbour. This Kimmeridge Clay has resulted in a series of landslides, forming West Weares and East Weares.2.4 kilometres (1.5 mi) underneath south Dorset lies a layer of Triassic rock salt, and Portland is one of four locations in the United Kingdom where the salt is thick enough to create stable cavities. Portland Gas applied to excavate 14 caverns to store 1,000,000,000 cubic metres (3.51010 cu ft) of natural gas, which is one percent of the UK's total annual demand. It was proposed that the caverns should be connected to the National gas grid at Mappowder via a 37-kilometre (23 mi) pipeline. Plans had it that the surface facilities should be complete to store the first gas in 2011, and the entire cavern space available for storage in winter 2013. As part of the 350 million scheme, the Grade II listed former Old Engine Shed would be converted into a 1.5 million educational centre with a cafe and an exhibition space about the geology of Portland.
[A]: What is the full name of the acronym UK?

[Q]: Passage: Barbara Holper was the daughter of Hieronymus Holper, under whom Albrecht the Elder served his apprenticeship as a goldsmith. The two men became friends, and when she came of age Holper gave his daughter into marriage when Durer senior was 40 and she was 15. The couple were compatible, well-matched and fond of each other. Yet their son's writings detail their difficult lives and many setbacks; three of their 18 children survived into adulthood 17 of whom had been born by the time of this portrait. After her husband died Barbara was destitute and went to live with her son. After she in turn died in 1514, her son wrote "This my pious Mother ... often had the plague and many other severe and strange illnesses, and she suffered great poverty, scorn, contempt, mocking words, terrors, and great adversities. Yet she bore no malice. Also she died hard ... I felt so grieved for her that I cannot express it."
Barbara is shown wearing a red dress and a matte white bonnet which fully covers her hair, indicating her marital status. Her headdress is draped with a long scarf or train which stretches down her neck and across her left shoulder, contrasting in colour and shape against the black head-wear of her husband. The lines of her face contain touches of white paint to give a highlighting and enlivening effect; they are especially evident around her eyes, the bridge of her nose and around her upper lip. Barbara was attractive in her youth; her son described her as having been "comely and of erect bearing". However, by the time of this portrait the effects of time and losing so many children weigh heavily on her face. The panel was grounded with white paint, while the composition seems to have changed significantly from the imprimatura. Faint traces of the original figuration are visible in parts of the background and in the darkened areas of her hood. At some point the panel was cut down at the left side, shifting the compositional balance and removing a portion of her shoulder and headdress.
[A]:
What are the names of the people who became friends?
