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: The term "Gadget" was a laboratory euphemism for a bomb, from which the laboratory's weapon physics division, "G Division", took its name in August 1944. At that time it did not refer specifically to the Trinity Test device as it had yet to be developed, but once it was, it became the laboratory code name. The Trinity Gadget was officially a Y-1561 device, as was the Fat Man used a few weeks later in the bombing of Nagasaki. The two were very similar, with only minor differences, the most obvious being the absence of fuzing and the external ballistic casing. The bombs were still under development, and small changes continued to be made to the Fat Man design.To keep the design as simple as possible, a near solid spherical core was chosen rather than a hollow one, although calculations showed that a hollow core would be more efficient in its use of plutonium. The core was compressed to prompt super-criticality by the implosion generated by the high explosive lens. This design became known as a "Christy Core" or "Christy pit" after physicist Robert F. Christy, who made the solid pit design a reality after it was initially proposed by Edward Teller. Along with the pit, the whole physics package was also informally nicknamed "Christy['s] Gadget".Of the several allotropes of plutonium, the metallurgists preferred the malleable δ phase. This was stabilized at room temperature by alloying it with gallium. Two equal hemispheres of plutonium-gallium alloy were plated with silver, and designated by serial numbers HS-1 and HS-2. The 6.19-kilogram (13.6 lb) radioactive core generated 15 W of heat, which warmed it up to about 100 to 110 °F (38 to 43 °C), and the silver plating developed blisters that had to be filed down and covered with gold foil; later cores were plated with nickel instead. The Trinity core consisted of just these two hemispheres. Later cores also included a ring with a triangular cross-section to prevent jets forming in the gap between them.
[A]: What is the code name of the device that was developed after it had a code name?


[Q]: Passage: Structure 12 lies to the east of Structure 11. It has also been excavated and, like Structure 11, it is covered with rounded boulders held together with clay. It lies to the east of the plaza in the southern area of the Central Group. The structure is a three-tiered platform with stairways on the east and west sides. The visible remains date to the Early Classic but they overlie Late Preclassic construction. A row of sculptures lines the west side of the structure, including six monuments, a stela and an altar. Further monuments line the east side, one of which may be the head of a crocodilian, the others are plain. Sculpture 69 is located on the south side of the structure.Structure 17 is located in the South Group, on the Santa Margarita plantation. It contained a Late Preclassic cache of 13 prismatic obsidian blades.Structure 32 is located near the western edge of the West Group.Structure 34 is in the West Group, at the eastern corner of Terrace 6.Structures 38, 39, 42 and 43 are joined by low platforms on the east side of a plaza on Terrace 7, aligned north–south. Structures 40, 47 and 48 are on south, west and north sides of this plaza. Structures 49, 50, 51, 52 and 53 form a small group on the west side of the terrace, bordered on the north by Terrace 9. Structure 42 is the tallest structure in the North Group, measuring about 11.5 metres (38 ft) high. All of these structures are mounds.Structure 46 is a mound at the edge of Terrace 8 in the North Group and dates from the Terminal Classic through to the Postclassic. The west side of the structure has been cut by a modern road.Structure 54 is built upon Terrace 8, to the north of Structure 46, in the North Group. It is surrounded by an open area without mounds that was probably a mixed residential and agricultural area. It dates from the Terminal Classic through to the Postclassic.Structure 57 is a large mound at the southern limit of the Central Group with an excellent view across the coastal plain. The structure was built in the Late Preclassic and underwent a second phase of construction in the Late Classic. It may have served as a look-out point.
[A]: Which structure dates from the Terminal Classic through to the Postclassic?


[Q]: Passage: In the months following Pink Moon's release, Drake became increasingly asocial and distant. He returned to live at his parents' home in Tanworth-in-Arden, and while he resented the regression, he accepted that his illness made it necessary. "I don't like it at home," he told his mother, "but I can't bear it anywhere else." His return was often difficult for his family; Gabrielle said, "good days in my parents' home were good days for Nick, and bad days were bad days for Nick. And that was what their life revolved around, really."Drake lived a frugal existence; his only income was a £20-a-week retainer he received from Island Records (equivalent to £238 in 2018). At one point he could not afford a new pair of shoes. He would disappear for days, sometimes arriving unannounced at friends' houses, uncommunicative and withdrawn. Robert Kirby described a typical visit: "He would arrive and not talk, sit down, listen to music, have a smoke, have a drink, sleep there the night, and two or three days later he wasn't there, he'd be gone. And three months later he'd be back." Nick's supervision partner at Cambridge, John Venning, saw him on a tube train in London and felt he was seriously depressed: "There was something about him which suggested that he would have looked straight through me and not registered me at all. So I turned around."John Martyn (who in 1973 wrote the title song of his album Solid Air about Drake) described Drake in this period as the most withdrawn person he had ever met. He would borrow his mother's car and drive for hours without purpose, until he ran out of petrol and had to ring his parents to ask to be collected. Friends recalled the extent to which his appearance had changed. During particularly bleak periods, he refused to wash his hair or cut his nails. Early in 1972, Drake had a nervous breakdown, and was hospitalized for five weeks. He was initially believed to suffer from major depression, although his former therapist suggested he was suffering from schizophrenia. His health problems were often reflected in his lyrics.
