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: After the Wicked Witch of the West is melted by a bucket of water, and Dorothy is sent back to her world, Glinda, the Good Witch of the South, decides to revive the Wicked Witch and remove her powers by storing them in a magic broom. Glinda then gives the magical broom to Dorothy's friends, Tin Woodman, Cowardly Lion, and Scarecrow, and they become the guardians of the broom.
Evilene, the Wicked Witch, conspires with her Flying Monkeys to retrieve her broom. However, a friendly little monkey named Ozzy forgets to close the gate of the castle and a battle ensues between the flying monkeys and the 'Bums of Oz.' Evilene retrieves her broom and repels the Champions of Oz from the castle. She then punishes Ozzy's father, transforming him into a chicken. Angered by the witch's spell on his father, Ozzy steals the broom from Evilene and runs away from the palace.
Ozzy reaches Glinda to find she has been paralyzed by accidentally drinking a magic potion created by her niece Gabby, who is unable to create an antidote without a vital ingredient based on wood. Gabby and Ozzy set off to find the Champions of Oz. They are pursued by the other Flying Monkeys.
They soon find Cowardly Lion, who is out of sorts due to the witch's spell, but with some effort they guide him to the north town, where they find the Tin Woodman, who is extremely depressed by the spell. The spell-raged Lion smashes the Tin Man to bits, but calms down when Ozzy accidentally hits him with the magic broom.
Ozzy, Gaby, and the Cowardly Lion take the Tin Man's parts to the Library of Oz where (due to the spell) Scarecrow is obsessively reading books in an effort to become more intelligent. He quickly repairs Tin with the help from a clue. However, the group is attacked by the Flying Monkeys, and in the chaos Ozzy cures Scarecrow of the spell's effects, but they are unable to save Gabby from being whisked away by the Flying Monkeys.
[A]: What are the names of the people who are pursued by Flying Monkeys?


[Q]: Passage: H. L. Hunley takes his ship, the H.L. Hunley, out in the Charleston, South Carolina  harbor and it sinks with all hands. As the blockade still needs to be broken, Brig. Gen. P. G. T. Beauregard has the ship raised and puts George E. Dixon in charge. He starts looking for a crew and after some difficulty finally finds enough volunteers to man it. They practice cranking the propeller. The crew do not all get along with each other. Dixon flashes back to the Battle of Shiloh, where a gold coin given to him by his wife (who was later killed in a steamboat explosion caused by a drifting mine) deflected a bullet and saved his life. They take the ship down and sit on the bottom to see how long they can stay down and almost get stuck. The U.S. Navy is warned about the sub. The crew votes that if after an attack they are stuck on the bottom, they will open the valves, flooding the ship, rather than suffocate. They go out to attack the USS Wabash, but the attack fails. Following the warning the ship has draped metal chain netting over the side. Also the rope which was attached to the torpedo they were to release under the ship gets loose and becomes entangled in the propeller. It has to be cut loose while sailors on the Wabash shoot at the Hunley. Beauregard proposes putting the torpedo at the end of a long spar. The USS Housatonic is ordered to change its position in the harbor and always be ready to steam, meaning it cannot hang metal netting over the side. The Hunley's second in command, Lt. Alexander, is ordered to Mobile, Alabama, and a young soldier who had been volunteering to join the crew is allowed to do so.
[A]:
What is the name of the object raised by Brig. Gen. P.G.T. Beauregard?
