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.

Input: Consider Input: 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.

Output: What is the code name of the device that was developed after it had a code name?


Input: Consider Input: Passage: Amy Winslow is an art student majoring in painting, who is all by her own. Her mother died when she was a child and her father is not around. As a student she has financial problems, so she is surprised when the couple Joan and Stuart Quinn (Connie Sellecca and David Dukes) decide to take her in their house for a small amount of rent. Little does Amy know that Joan is following her every step through secret cameras, and that she has a hidden agenda for her. Initially, Amy is very content living with the Quinns, believing that she has found the family she has never had. When she loses the university's financial aide through an administration error, Joan immediately steps in to take care of her. They both drink a large amount of wine, and then Joan announces that because she is infertile, they are looking for a surrogate mother. She then tells Amy that they feel that she is the perfect candidate. Amy is flattered, and next day discusses the situation with her friendly teacher Eric Shaw. She then agrees when the Quinns propose to pay for her college fees if she helps them out.
When Amy is a few months pregnant, Joan starts to show strange behavior. Amy feels smothered by Joan's overbearing attitude, feeling that she is being treated like a ten-year-old child. Her oil painting being taken away, Amy looks for it in the basement, only to find old baby clothes. Joan catches her, and becomes furious, scaring Amy away. She later tries to explain the situation by saying that she was pregnant four years ago, though had a miscarriage. Amy does not believe her story, though Eric - who was already 'warned' by Joan that Amy might act paranoid - tells her to focus on her painting, not on the Quinns.

Output: Why does Amy agree to be a surrogate mother?


Input: Consider Input: Passage: Ieoh Ming Pei, FAIA, RIBA (born 26 April 1917), commonly known as I. M. Pei, is a Chinese American architect.  Born in Guangzhou and raised in Hong Kong and Shanghai, Pei drew inspiration at an early age from the gardens at Soochow. In 1935, he moved to the United States and enrolled in the University of Pennsylvania's architecture school, but quickly transferred to the Massachusetts Institute of Technology. He was unhappy with the focus at both schools on Beaux-Arts architecture, and spent his free time researching emerging architects, especially Le Corbusier. After graduating, he joined the Harvard Graduate School of Design (GSD) and became a friend of the Bauhaus architects Walter Gropius and Marcel Breuer. In 1948, Pei was recruited by New York City real estate magnate William Zeckendorf, for whom he worked for seven years before establishing his own independent design firm I. M. Pei & Associates in 1955, which became I. M. Pei & Partners in 1966 and later in 1989 became Pei Cobb Freed & Partners. Pei retired from full-time practice in 1990. Since then, he has taken on work as an architectural consultant primarily from his sons' architectural firm Pei Partnership Architects.
Pei's first major recognition came with the National Center for Atmospheric Research in Colorado (designed in 1961, and completed in 1967). His new stature led to his selection as chief architect for the John F. Kennedy Library in Massachusetts. He went on to design Dallas City Hall and the East Building of the National Gallery of Art. He returned to China for the first time in 1975 to design a hotel at Fragrant Hills, and designed Bank of China Tower, Hong Kong, a skyscraper in Hong Kong for the Bank of China fifteen years later. In the early 1980s, Pei was the focus of controversy when he designed a glass-and-steel pyramid for the Musée du Louvre in Paris. He later returned to the world of the arts by designing the Morton H. Meyerson Symphony Center in Dallas, the Miho Museum in Japan, the Suzhou Museum in Suzhou, Museum of Islamic Art in Qatar, and the Grand Duke Jean Museum of Modern Art, abbreviated to Mudam, in Luxembourg.
Pei has won a wide variety of prizes and awards in the field of architecture, including the AIA Gold Medal in 1979, the first Praemium Imperiale for Architecture in 1989, and the Lifetime Achievement Award from the Cooper-Hewitt, National Design Museum in 2003. In 1983, he won the Pritzker Prize, sometimes called the Nobel Prize of architecture.


Output: What is the last name of the person who moved to the US in 1935?
