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 Q]: 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 A]: What is the first name of the person who appointed Hugh Robertson as the complex manager?

[EX Q]: Passage: Dr. Watson is serving as resident doctor at Musgrave Manor in Northumberland, a stately home which is also used as a hospital for a number of servicemen suffering from shell shock.When Sally Musgrave displays her feelings for one of the wounded American fighter pilots, Captain Pat Vickery, who is currently recovering at the family estate, her brothers Geoffrey and Phillip are quick to show their dismay.
Then one of the physicians working at the estate, Dr. Sexton, is assaulted by an unknown assailant when out on a walk. Dr. John Watson, who is in charge of the medical facility, goes to fetch his dear friend Sherlock Holmes to bring some clarity to the case of the attack.
Upon his arrival to the estate, Sherlock Holmes discovers the dead body of one of the brothers, Geoffrey. Inspector Lestrade of the Scotland Yard is put on the case to solve the murder, and immediately arrests the captain as a suspect.
Holmes is of another opinion about the flyer's guilt and continues to investigate on his own.  Phillip is formally made the new head of the estate the next day with the aid of his sister.  But after only one day of ruling the estate, Phillip too is found murdered, lying in the trunk of the car.
Lestrade suspects the family butler, Alfred Brunton, to be the murderer because Phillip had just fired the butler. Trying to arrest the butler, Lestrade gets lost in the manor's secret passageways. Meanwhile Holmes and Watson look into the special "Musgrave Ritual" that the family uses to appoint the new head of the family. They find the words used in the ritual hidden in Sally's room and try to copy the ritual, which involves replaying a giant chess game on the checkered floor of the house main hall. As pieces in the game they use the household staff.
[EX A]: Who fired the butler before the crimes were committed?

[EX Q]: Passage: Minnesota has some of the earth's oldest rocks, gneisses that are about 3.6 billion years old (80% as old as the planet). About 2.7 billion years ago, basaltic lava poured out of cracks in the floor of the primordial ocean; the remains of this volcanic rock formed the Canadian Shield in northeast Minnesota. The roots of these volcanic mountains and the action of Precambrian seas formed the Iron Range of northern Minnesota. Following a period of volcanism 1.1 billion years ago, Minnesota's geological activity has been more subdued, with no volcanism or mountain formation, but with repeated incursions of the sea, which left behind multiple strata of sedimentary rock.In more recent times, massive ice sheets at least one kilometer thick ravaged the state's landscape and sculpted its terrain. The Wisconsin glaciation left 12,000 years ago. These glaciers covered all of Minnesota except the far southeast, an area characterized by steep hills and streams that cut into the bedrock. This area is known as the Driftless Zone for its absence of glacial drift. Much of the remainder of the state outside the northeast has 50 feet (15 m) or more of glacial till left behind as the last glaciers retreated. Gigantic Lake Agassiz formed in the northwest 13,000 years ago. Its bed created the fertile Red River valley, and its outflow, glacial River Warren, carved the valley of the Minnesota River and the Upper Mississippi downstream from Fort Snelling. Minnesota is geologically quiet today; it experiences earthquakes infrequently, and most of them are minor.
[EX A]:
What is the name of the area in Minnesota was not covered by massive ice sheets?
