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: An Army-OSRD council on 25 June 1942 decided to build a pilot plant for plutonium production in Red Gate Woods southwest of Chicago. In July, Nichols arranged for a lease of 1,025 acres (415 ha) from the Cook County Forest Preserve District, and Captain James F. Grafton was appointed Chicago area engineer. It soon became apparent that the scale of operations was too great for the area, and it was decided to build the plant at Oak Ridge, and keep a research and testing facility in Chicago.Delays in establishing the plant in Red Gate Woods led Compton to authorize the Metallurgical Laboratory to construct the first nuclear reactor beneath the bleachers of Stagg Field at the University of Chicago. The reactor required an enormous amount of graphite blocks and uranium pellets. At the time, there was a limited source of pure uranium. Frank Spedding of Iowa State University were able to produce only two short tons of pure uranium. Additional three short tons of uranium metal was supplied by Westinghouse Lamp Plant which was produced in a rush with makeshift process. A large square balloon was constructed by Goodyear Tire to encase the reactor. On 2 December 1942, a team led by Enrico Fermi initiated the first artificial self-sustaining nuclear chain reaction in an experimental reactor known as Chicago Pile-1. The point at which a reaction becomes self-sustaining became known as "going critical". Compton reported the success to Conant in Washington, D.C., by a coded phone call, saying, "The Italian navigator [Fermi] has just landed in the new world."In January 1943, Grafton's successor, Major Arthur V. Peterson, ordered Chicago Pile-1 dismantled and reassembled at Red Gate Woods, as he regarded the operation of a reactor as too hazardous for a densely populated area. At the Argonne site, Chicago Pile-3, the first heavy water reactor, went critical on 15 May 1944. After the war, the operations that remained at Red Gate moved to the new site of the Argonne National Laboratory about 6 miles (9.7 km) away.

Q: Passage: From the moment the three were grounded on 14 July, Strindberg's highly specialized cartographic camera, which had been brought to map the region from the air, became instead a means of recording daily life in the icescape and the constant danger and drudgery of the trek. Strindberg took about 200 photos with his seven-kilogram (15 lb) camera over the course of the three months they spent on the pack ice, one of the most famous being his picture of Andrée and Frænkel contemplating the fallen Eagle (see image above).Andrée and Frænkel also kept meticulous records of their experiences and geographical positions, Andrée in his "main diary," Frænkel in his meteorological journal. Strindberg's own stenographic diary was more personal in content, and included his general reflections on the expedition, as well as several messages to his fiancée Anna Charlier. All three manuscripts were eventually retrieved from the ice on Kvitøya in 1930.
The Eagle had been stocked with safety equipment such as guns, snowshoes, sleds, skis, a tent, a small boat (in the form of a bundle of bent sticks, to be assembled and covered with balloon silk), most of it stored not in the basket but in the storage space arranged above the balloon ring. These items had not been put together with great care, or with any acknowledgment of adopting indigenous peoples' techniques for dealing with the extreme environment. In this, Andrée contrasted not only with later but also with many earlier explorers.
Sven Lundström points to the agonizing extra efforts that became necessary for the team due to Andrée's mistaken design of the sleds, with a rigid construction that borrowed nothing from the long proven Inuit sleds, and were so impractical for the difficult terrain. Andrée called it "dreadful terrain", with channels separating the ice floes, high ridges, and partially iced-over melt ponds. The men's clothes included no furs but were woolen coats and trousers, plus oilskins. They wore the oilskins but the explorers reported always seeming to be damp or wet from the half-frozen pools of water on the ice and the typically foggy, humid Arctic summer air, and preoccupied with drying their clothes, mainly by wearing them. It would have meant certain death to lose the provisions lashed to one of the inconvenient sleds into one of the many channels that had to be laboriously crossed.

Q: Passage: While travelling through Utah, Jack Carter picks up a hitchhiker, but kicks him out after a few minutes due to the man hitting on him. Hours later, Jack stops in a secluded area, and begins digging a grave for the woman he had bound and gagged in the back of his pickup truck.
Four women (Melinda, Patty, Kristina, and Denise) from Colorado Springs are driving through the area on their way to a nurse's conference in Las Vegas. Spotting Jack hitchhiking, the quartet pick him up, and soon after experience car trouble, forcing them to stop at a roadside motel. The manager tells the group that the nearest service station does not open until the morning, so they elect to stay. During the night, Jack shows interest in Melinda, and has rough sex with Kristina, who has a fiancé.
In the morning, the mechanic arrives, and is shot to death by Jack after the two travel to Jack's abandoned truck. Jack returns to the motel, where he murders the manager and takes the women captive after drugging them. Jack gives a misogynistic speech, and implies he is doing this due to having been "betrayed" by his girlfriend or wife. While sexually assaulting Denise and Melinda, Jack is knocked out by the latter, who tries to escape with her friends. The vehicles will either not work, or are missing their keys, so the women decide to kill Jack, who awakens while being attacked, and fatally shoots Kristina. The others are recaptured, and while Jack is binding Melinda (who he has developed a fondness for, and regards as "special") a married couple arrives, looking for a room.
