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: In the year 2074, the cybernetics market is dominated by two rival companies: USA's Pinwheel Robotics and Japan's Kobayashi Electronics. 'Cyborgs' are commonplace, used for anything from soldiers to prostitutes. Casella "Cash" Reese is a Pinwheel prototype cyborg developed for corporate espionage and assassination. She is filled with a liquid explosive called "Glass Shadow". Pinwheel's CEO, Martin Dunn, plans to eliminate the entire Kobayashi board of directors using Cash as a suicide bomber to precipitate a hostile takeover of the company and obtain a monopoly over the cyborg market.
Cash is programmed to mimic human senses and emotions such as fear, love, pain, and hate. Guided by Mercy, a renegade prototype cyborg who can communicate through any electronic device, Cash and her combat trainer Colton "Colt" Ricks escape the Pinwheel facility so Cash can avoid self-destruction, something that most corporate espionage cyborgs face. They're relentlessly pursued by Pinwheel's hired killer or "wiretapper", Daniel Bench.
Bench must also deal with a rival bounty hunter named Chen, who plans on killing Ricks and reprogramming Cash to have her blow up Pinwheel instead as a means to punish the company's director, Dunn, as reprisal for an earlier act from Dunn that displeased her. However, Chen and Ricks get into a fight, which results in Chen getting electrocuted by a fuse box.
[A]: Who is the head of the company that makes cyborgs filled with liquid explosive?


[Q]: Passage: Makeba was among the most visible people campaigning against the apartheid system in South Africa, and was responsible for popularising several anti-apartheid songs, including "Meadowlands" by Strike Vilakezi and "Ndodemnyama we Verwoerd" (Watch out, Verwoerd) by Vuyisile Mini. Due to her high profile, she became a spokesperson of sorts for Africans living under oppressive governments, and in particular for black South Africans living under apartheid. When the South African government prevented her from entering her home country, she became a symbol of "apartheid's cruelty", and she used her position as a celebrity by testifying against apartheid before the UN in 1962 and 1964. Many of her songs were banned within South Africa, leading to Makeba's records being distributed underground, and even her apolitical songs being seen as subversive. She thus became a symbol of resistance to the white-minority government both within and outside South Africa. In an interview in 2000, Masekela said that "there [was] nobody in Africa who made the world more aware of what was happening in South Africa than Miriam Makeba."Makeba has also been associated with the movement against colonialism, with the civil rights and black power movements in the US, and with the Pan-African movement. She called for unity between black people of African descent across the world: "Africans who live everywhere should fight everywhere. The struggle is no different in South Africa, the streets of Chicago, Trinidad or Canada. The Black people are the victims of capitalism, racism and oppression, period". After marrying Carmichael she often appeared with him during his speeches; Carmichael later described her presence at these events as an asset, and Feldstein wrote that Makeba enhanced Carmichael's message that "black is beautiful". Along with performers such as Simone, Lena Horne, and Abbey Lincoln, she used her position as a prominent musician to advocate for civil rights. Their activism has been described as simultaneously calling attention to racial and gender disparities, and highlighting "that the liberation they desired could not separate race from sex". Makeba's critique of second-wave feminism as being the product of luxury led to observers being unwilling to call her a feminist. Scholar Ruth Feldstein stated that Makeba and others influenced both black feminism and second-wave feminism through their advocacy, and the historian Jacqueline Castledine referred to her as one of the "most steadfast voices for social justice".
[A]: What is the first name of the person who became a symbol of resistance to the white-minority government?


[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?
