Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Reason: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

Now, solve this instance: Passage: In a December 8, 1953 speech to the United Nations, President Dwight D. Eisenhower announced a new Atoms for Peace policy, and Congress enacted his program into law the following year. Atoms for Peace "made funding accessible to anyone who had the imagination, if not the ability, to harness the atom's power for peaceful purposes". Under the new program, the airplane manufacturer Curtiss-Wright Corporation sought a large isolated area in central Pennsylvania "for the development of nuclear-powered jet engines and to conduct research in nucleonics, metallurgy, ultrasonics, electronics, chemicals and plastics". Curtiss-Wright worked closely with the state, and in June 1955, Governor George M. Leader signed legislation that authorized the construction of a research facility at Quehanna. The Commonwealth of Pennsylvania sold Curtiss-Wright 8,597 acres (3,479 ha) for $181,250 ($22.50 an acre, $55.60 a hectare), and gave the company a 99-year lease on the remaining 42,596 acres (17,238 ha) at $30,000 a year. Curtiss-Wright controlled 51,193 acres (80.0 sq mi; 207.2 km2) in a regular 16-sided polygon, which was easier to fence than a circular area.The state constructed $1.6 million of roads to the area; the Quehanna Highway was built on parts of an old CCC road, which followed an earlier logging railroad grade. Pennsylvania also canceled 212 camp site leases to help ensure security for the installation. Curtiss-Wright built three facilities on its land. The first was a nuclear research center with a nuclear reactor and six shielded radiation containment chambers for handling radioactive isotopes, referred to as hot cells, at the end of Reactor Road. The second was for jet engine trials, and had two test cells with bunkers just north of Quehanna Highway, about 0.5 miles (0.8 km) apart. The northern test cell was at the center of the 16-sided polygon; even if a jet engine broke its moorings, it could not leave the polygonal area. Both of these were on the land which Curtiss-Wright had purchased, which was a regular octagon surrounded with a 24-mile (39 km) fence built by forest rangers, supervised from three guard houses on Quehanna Highway and Wykoff Run Road. The third installation was an industrial complex at the southeast edge of the polygon, in Karthaus Township, on the Quehanna Highway. At this site, a Curtiss-Wright division manufactured Curon foam for furniture and household products and used beryllium oxide to make high-temperature ceramics for application in the nuclear industry.
Student:
In what town was the third installation purchased by the man who controlled 51,193 acres?
