TASK DEFINITION: In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.
PROBLEM: Passage: In London, Professor Henry Higgins, a scholar of phonetics, believes that the accent and tone of one's voice determines a person's prospects in society ("Why Can't the English?"). At Covent Garden one evening, he meets Colonel Hugh Pickering, himself a phonetics expert who had come all the way from India to see him. Higgins boasts he could teach anyone to speak so well he could pass them off as a duke or duchess at an embassy ball, even the young woman with a strong Cockney accent named Eliza Doolittle who tries to sell them flowers. Eliza's ambition is to work in a flower shop, but her accent makes that impossible ("Wouldn't It Be Loverly"). The following morning, Eliza shows up at Higgins' home, seeking lessons. Pickering is intrigued and offers to cover all the attendant expenses if Higgins succeeds. Higgins agrees, and describes how women ruin lives ("I'm an Ordinary Man").
Eliza's father, Alfred P. Doolittle, a dustman, learns of his daughter's new residence ("With a Little Bit of Luck"). He shows up at Higgins' house three days later, ostensibly to protect his daughter's virtue, but in reality simply to extract some money from Higgins, and is bought off with £5. Higgins is impressed by the man's honesty, his natural gift for language, and especially his brazen lack of morals. Higgins recommends Alfred to a wealthy American who is interested in morality. 
Eliza endures Higgins' demanding teaching methods and treatment of her personally ("Just You Wait"). She makes little progress, but just as she, Higgins, and Pickering are about to give up, Eliza finally "gets it" ("The Rain in Spain"); she instantly begins to speak with an impeccable upper class accent ("I Could Have Danced All Night"). 
Question: What's the last name of the man that will pay for Eliza's lessons, if successful?

SOLUTION: Pickering.

PROBLEM: Passage: The music video for "Single Ladies" was shot immediately after that of "If I Were a Boy", but it received less attention during production than the "higher-gloss, higher-profile video" for "If I Were a Boy". Both videos were shot in black-and-white in New York City and were directed by Jake Nava, with whom Beyoncé had worked on previous music videos including "Crazy in Love" and "Beautiful Liar". "Single Ladies" was choreographed by Frank Gatson Jr. and JaQuel Knight, and incorporates J-Setting choreography. The two music videos premiered on MTV's Total Request Live show on October 13, 2008 to reinforce the concept of conflicting personalities. The videos were released to other media outlets on the same date and subsequently included on Beyoncé's remix album with videography, Above and Beyoncé, and the platinum edition of I Am... Sasha Fierce.
Beyoncé told Simon Vozick-Levinson of Entertainment Weekly that the inspiration for the video was a 1969 Bob Fosse routine entitled "Mexican Breakfast" seen on The Ed Sullivan Show, which featured Fosse's wife, Gwen Verdon, dancing with two other women. "Mexican Breakfast" had become an Internet viral sensation the previous summer after Unk's "Walk It Out" was dubbed over the original mix. Beyoncé wanted to attempt a similar dance and eventually, the choreography of "Single Ladies" was liberally adapted from "Mexican Breakfast":
I saw a video on YouTube. [The dancers] had a plain background and it was shot on the crane; it was 360 degrees, they could move around. And I said, 'This is genius.' We kept a lot of the Fosse choreography and added the down-south thing—it's called J-Setting, where one person does something and the next person follows. So it was a strange mixture ... It's like the most urban choreography, mixed with Fosse—very modern and very vintage. 
Question: What  videos were released to other media outlets on the same date and subsequently included on Beyoncé's remix album with videography?

SOLUTION: Single Ladies.

PROBLEM: Passage: The next day, 2 December 1942, everybody assembled for the experiment. There were 49 scientists present. Although most of the S-1 Executive Committee was in Chicago, only Crawford Greenewalt was present, at Compton's invitation. Other dignitaries present included Szilard, Wigner and Spedding. Fermi, Compton, Anderson and Zinn gathered around the controls on the balcony, which was originally intended as a viewing platform. Samuel Allison stood ready with a bucket of concentrated cadmium nitride, which he was to throw over the pile in the event of an emergency. The startup began at 09:54. Walter Zinn removed the zip, the emergency control rod, and secured it. Norman Hilberry stood ready with an axe to cut the scram line, which would allow the zip to fall under the influence of gravity. While Leona Woods called out the count from the boron trifluoride detector in a loud voice, George Weil, the only one on the floor, withdrew all but one of the control rods. At 10:37 Fermi ordered Weil to remove all but 13 feet (4.0 m) of the last control rod. Weil withdrew it 6 inches (15 cm) at a time, with measurements being taken at each step.The process was abruptly halted by the automatic control rod reinserting itself, due to its trip level being set too low. At 11:25, Fermi ordered the control rods reinserted. He then announced that it was lunch time.The experiment resumed at 14:00. Weil worked the final control rod while Fermi carefully monitored the neutron activity. Fermi announced that the pile had gone critical (reached a self-sustaining reaction) at 15:25. Fermi switched the scale on the recorder to accommodate the rapidly increasing electrical current from the boron trifluoride detector. He wanted to test the control circuits, but after 28 minutes, the alarm bells went off to notify everyone that the neutron flux had passed the preset safety level, and he ordered Zinn to release the zip. The reaction rapidly halted. The pile had run for about 4.5 minutes at about 0.5 watts. Wigner opened a bottle of Chianti, which they drank from paper cups.Compton notified Conant by telephone. The conversation was in an impromptu code:
Compton: The Italian navigator has landed in the New World.Conant: How were the natives?
Compton: Very friendly. 
Question: What is the first name of the person who withdrew the control rod  6 inches (15 cm) at a time, with measurements being taken at each step?

SOLUTION:
George.
