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: After the war and following several earlier miscarriages, Irina gave birth to their daughter, Mary Moore, in March 1946. The child was named after Moore's mother, who had died two years earlier. Both the loss of his mother and the arrival of a baby focused Moore's mind on the family, which he expressed in his work by producing many "mother-and-child" compositions, although reclining and internal/external figures also remained popular. In the same year, Moore made his first visit to America when a retrospective exhibition of his work opened at the Museum of Modern Art in New York City.Before the war, Moore had been approached by educator Henry Morris, who was trying to reform education with his concept of the Village College. Morris had engaged Walter Gropius as the architect for his second village college at Impington near Cambridge, and he wanted Moore to design a major public sculpture for the site. The County Council, however, could not afford Gropius's full design, and scaled back the project when Gropius emigrated to America. Lacking funds, Morris had to cancel Moore's sculpture, which had not progressed beyond the maquette stage.  Moore was able to reuse the design in 1950 for a similar commission outside a secondary school for the new town of Stevenage. This time, the project was completed and Family Group became Moore's first large-scale public bronze.In the 1950s, Moore began to receive increasingly significant commissions.  He exhibited Reclining Figure: Festival at the Festival of Britain in 1951, and in 1958 produced a large marble reclining figure for the UNESCO building in Paris.  With many more public works of art, the scale of Moore's sculptures grew significantly and he started to employ an increasing number of assistants to work with him at Much Hadham, including Anthony Caro and Richard Wentworth.On the campus of the University of Chicago in December 1967, 25 years to the minute after the team of physicists led by Enrico Fermi achieved the first controlled, self-sustaining nuclear chain reaction, Moore's Nuclear Energy was unveiled on the site of what was once the university's football field stands, in the rackets court beneath which the experiments had taken place. This 12-foot-tall piece in the middle of a large, open plaza is often thought to represent a mushroom cloud topped by a massive human skull, but Moore's interpretation was very different. He once told a friend that he hoped viewers would "go around it, looking out through the open spaces, and that they may have a feeling of being in a cathedral."  In Chicago, Illinois, Moore also commemorated science with a large bronze sundial, locally named Man Enters the Cosmos (1980), which was commissioned to recognise the space exploration program.

A: What was the first name of Moore's mother?

Q: Passage: In his field and day, Wright was certainly eclipsed by his rival the more prolific Lely, to whom he is often compared. One critic, Millar, observes that any comparisons undertaken would "ruthlessly expose Wright's weaknesses and mannerisms" but that positively "they would also demonstrate his remarkable independence, his unfailing integrity and charm, the sources of which must partly lie in his unusual origins, fragmented career and attractive personality". Millar suggests that a particularly useful comparison can be made between Lely and Wright's respective portrayals of the Duchess of Clevland (Barbara Villiers) (above). Whereas Lely portrayed her as a "full-blown and palpably desirable strumpet", the more seriously minded Wright, who was not really in sympathy with the morality of the new court and its courtesans, rendered a more puppet-like figure.However, even if Lely was considered the more masterly and fashionable of the two in seventeenth-century Britain, Wright is generally accepted as portraying the more lively and realistic likenesses of his subjects, a fact that reinforces Pepys's observation that Lely's work was "good but not like". Neither should Wright's realism be confused with a prudishness; as can be seen, for example, in his portrait the lady, thought to be Ann Davis (right). The picture, with the sitter's clothing left undone and her modesty barely preserved by a red drape, has been described as exhibiting a fresh – even risky – reality: erotic by contemporary standards. Whereas Wright's contemporaries might have used the ‘disguise’ of presenting the sitter in the guise of a classical goddess to protect against accusation of  salaciousness, Wright's portrait rather depends on his realism, notably in his flesh tones, and depth.

A: What is the name of the person who was portrayed as a "full-blown and palpably desirable strumpet?"?

Q: Passage: As the North Tower collapsed on September 11, 2001, heavy debris hit 7 World Trade Center, damaging the south face of the building and starting fires that continued to burn throughout the afternoon. The collapse also caused damage to the southwest corner between Floors 7 and 17 and on the south face between Floor 44 and the roof; other possible structural damage included a large vertical gash near the center of the south face between Floors 24 and 41. The building was equipped with a sprinkler system, but had many single-point vulnerabilities for failure: the sprinkler system required manual initiation of the electrical fire pumps, rather than being a fully automatic system; the floor-level controls had a single connection to the sprinkler water riser; and the sprinkler system required some power for the fire pump to deliver water. Additionally, water pressure was low, with little or no water to feed sprinklers.After the North Tower collapsed, some firefighters entered 7 World Trade Center to search the building. They attempted to extinguish small pockets of fire, but low water pressure hindered their efforts. Over the course of the day, fires burned out of control on several floors of 7 World Trade Center, the flames visible on the east side of the building. During the afternoon, the fire was also seen on floors 6–10, 13–14, 19–22, and 29–30. In particular, the fires on floors 7 through 9 and 11 through 13 continued to burn out of control during the afternoon. At approximately 2:00 pm, firefighters noticed a bulge in the southwest corner of 7 World Trade Center between the 10th and 13th floors, a sign that the building was unstable and might collapse. During the afternoon, firefighters also heard creaking sounds coming from the building. Around 3:30 pm, FDNY Chief Daniel A. Nigro decided to halt rescue operations, surface removal, and searches along the surface of the debris near 7 World Trade Center and evacuate the area due to concerns for the safety of personnel. The fire expanded the girders of the building, causing some to lose their structural integrity. This led column number 79, a critical column supporting a large part of the 13th floor, to buckle, causing the floors above it to collapse to the fifth floor; however, this could not be seen from outside the building. The structure also developed cracks in the facade just before the entire building started to fall. According to FEMA, this collapse started at 5:20:33 pm EDT when the east mechanical penthouse started crumbling. Differing times are given as to what time the building completely collapsed: at 5:21:10 pm EDT according to FEMA, and at 5:20:52 pm EDT according to NIST. There were no casualties associated with the collapse. NIST found no evidence to support conspiracy theories such as the collapse being the result of explosives; it found that a combination of factors including physical damage, fire and the building's unusual construction set off a chain-reaction collapse.

A:
What was the last name of the person who halt rescue operations in 7 World Trade Center?
