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.

Ex Input:
Passage: The management of Rockefeller Center shifted around this time. In November 1936, John Todd was featured in two New Yorker articles that emphasized his role in the complex's construction. At the same time, Nelson was gaining clout within Rockefeller Center Inc., and he disagreed with nearly all of Todd's suggestions. Nelson's father, John, was relinquishing his responsibilities, since the Rockefeller family's youngest son David had moved out of the family home at 10 West 54th Street, and John was now focusing on his own personal life. By April 1937, Todd regretted his decision to be featured in The New Yorker. In March 1938, Nelson became the president of Rockefeller Center Inc. He then fired Todd as the complex's manager and appointed Hugh Robertson in his place. Nelson and Robertson wanted to avoid workers' strikes, which would delay the completion of construction. Nelson, Robertson, and the workers' unions agreed to a contract in which the unions would not strike, Robertson would not lock out union workers, and both would agree to arbitration if a labor dispute arose. Rockefeller Center was one of Nelson's primary business ventures until 1958, when he was elected Governor of New York.Public relations officials were hired to advertise the different parts of the complex, such as the gardens and the plaza. Merle Crowell set up a viewing platform on the east side of Rockefeller Center and founded the facetious "Sidewalk Superintendents' Club" so the public could view construction.

Ex Output:
What is the first name of the person who appointed Hugh Robertson as the complex manager?

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 (3.5×1010 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 café and an exhibition space about the geology of Portland.

Ex Output:
What is the full name of the acronym UK?

Passage: Imagery has always been an important part of the Orb's persona. This is most prominent during live performances, where they often project surreal images against onstage screens. Common images include morphing faces, futuristic cityscapes, and aliens. They have long associated their act with absurd symbology with images such as floating pigs. This has carried over to their music videos, most of which are spacy, brightly coloured montages of surreal images including astronauts, clouds, and neon dolphins. Because of their use of psychedelic images at shows, the Orb's shows are frequently compared to those of Pink Floyd, who also used in-show imagery and films. Paterson cites Godfrey Reggio's and Philip Glass's film Koyaanisqatsi as a primary influence to their concert imagery.The Orb's album art features much of the same imagery as their live act. Graphic design group The Designers Republic created the cover art for the earlier work, including Adventures Beyond the Ultraworld, U.F.Orb, and the singles from those two albums. For their next album, the Orb poked fun at their Pink Floyd comparisons with the cover of Live 93 featuring a floating stuffed sheep over the Battersea Power Station, which had appeared on the cover of Pink Floyd's Animals. The artwork found in Badorb.com releases was similar to the Orb's odd artwork of the mid-1990s, as it was stylistically similar and contained little writing. Paterson has also dabbled in the creation of cover art himself, designing the cover of Okie Dokie It's The Orb on Kompakt.

Ex Output:

What is the name of the group for whose concert imagery Koyaanisqatsi is a primary influence?
