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 Rosetta Stone is listed as "a stone of black granodiorite, bearing three inscriptions ... found at Rosetta" in a contemporary catalogue of the artefacts discovered by the French expedition and surrendered to British troops in 1801. At some period after its arrival in London, the inscriptions on the stone were coloured in white chalk to make them more legible, and the remaining surface was covered with a layer of carnauba wax designed to protect the Rosetta Stone from visitors' fingers. This gave a dark colour to the stone that led to its mistaken identification as black basalt. These additions were removed when the stone was cleaned in 1999, revealing the original dark grey tint of the rock, the sparkle of its crystalline structure, and a pink vein running across the top left corner. Comparisons with the Klemm collection of Egyptian rock samples showed a close resemblance to rock from a small granodiorite quarry at Gebel Tingar on the west bank of the Nile, west of Elephantine in the region of Aswan; the pink vein is typical of granodiorite from this region.The Rosetta Stone is 1,123 millimetres (3 ft 8 in) high at its highest point, 757 mm (2 ft 5.8 in) wide, and 284 mm (11 in) thick. It weighs approximately 760 kilograms (1,680 lb). It bears three inscriptions: the top register in Ancient Egyptian hieroglyphs, the second in the Egyptian Demotic script, and the third in Ancient Greek. The front surface is polished and the inscriptions lightly incised on it; the sides of the stone are smoothed, but the back is only roughly worked, presumably because this would have not been visible when it was erected.
[EX A]: How many kilograms does the Rosetta Stone weigh?

[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: The city's zoo, the Tulsa Zoo, was voted "America's Favorite Zoo" in 2005 by Microsoft Game Studios in connection with a national promotion of its Zoo Tycoon 2 computer game. The zoo encompasses a total of 84 acres (34 ha) with over 2,600 animals representing 400 species. The zoo is located in 2,820-acre (1,140 ha) Mohawk Park (the third largest municipal park in the United States) which also contains the 745-acre (301 ha) Oxley Nature Center.  
The Tulsa State Fair, operating in late September and early October, attracts over one million people during its 10-day run, and the city's Oktoberfest celebration was named one of the top 10 in the world by USA Today and one of the top German food festivals in the nation by Bon Appetit magazine. A number of other cultural heritage festivals are held in the city throughout the year, including the Intertribal Indian Club Powwow of Champions in August; Scotfest, India Fest, Greek Festival, and Festival Viva Mexico in September; ShalomFest in October; Dia de Los Muertos Art Festival in November; and the Asian-American Festival in May. The annual Mayfest arts and crafts festival held downtown was estimated to have drawn more than 365,000 people in its four-day run in 2012. On a smaller scale, the city hosts block parties during a citywide "Block Party Day" each year, with festivals varying in size throughout city neighborhoods. Tulsa has one major amusement park attraction, Safari Joe's H2O Water Park (formerly Big Splash Water Park), featuring multi-story water slides, large wave pools, and a reptile exhibit. Until 2006, the city also hosted Bell's Amusement Park, which closed after Tulsa County officials declined to renew its lease agreement.
[EX A]:
What is located in a 2,820-acre park, along with a nature center?
