TASK DEFINITION: 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.
PROBLEM: Passage: When Stephen Herrick, a sedate, mild-mannered shipping magnate, loses his opera tickets, Mrs. Grange, the aggressive mother of his fiancée Cecilia, insists upon being seated in the Herrick box anyway. Upon finding the Duncan family ensconced in their box, Mrs. Grange incites an argument that culminates with Dot Duncan hitting Stephen with her handbag.
After the Herrick party surrenders their seats to the Duncans, Dot realizes that her brother Pigeon found Stephen's lost tickets, and the embarrassed Duncans flee the theater.
The next day, at the offices of Herrick and Martin, Stephen is introduced to his new secretary, Dot Duncan. Recognizing Dot as his assailant from the previous evening, he dismisses her, but after she explains the confusion over the tickets, Stephen relents.
Soon after, Dot's beau, wrestler Claudius J. "Coffee Cup" Cup, returns from the Navy, promising to settle down and not re-enlist. While Dot and Coffee Cup are strolling down the street one day, Coffee Cup spots his pal Eddie, who he boasts, can grow four inches just by stretching. Eddie's aptitude for elongation draws a crowd, and soon Coffee Cup is taking bets from the skeptical onlookers. Stephen is drawn into the group when Dot borrows five dollars from him, and when the contest ends in a brawl in which Stephen is knocked unconscious, Coffee Cup takes him to the Duncan house to recover. Stephen awakens to the chaos of the Duncan household as Coffee Cup practices his wrestling technique on Pigeon, Mrs. Duncan delivers a neighbor's baby and Ivory, a sailor, tinkles the piano keys. Stephen is so delighted by Dot's boisterous family and friends that he accompanies her and Coffee Cup to a dance hall and congas the night away, forgetting all about his date with the snobbish Cecilia.

SOLUTION: Who finds the shipping magnate's opera tickets?

PROBLEM: Passage: Three men rob a millionaire of diamonds aboard an airliner in flight. When Police Superintendent Benting tries to intervene, Jack Drake, another passenger, knocks him out to save him from being shot. The thieves force the pilot to land so they can dump the passengers. However, the men find the diamonds have already been stolen by someone else (Drake). 
Drake is a sort of modern-day Robin Hood. He donates the proceeds of his latest robbery to fund the stalled construction of the "New Social Institute". He even writes a book, "Crackerjack": The true story of my exploits., which becomes a bestseller. Everybody is reading it, including the people at Scotland Yard and Baroness Von Haltz, and wondering if it is fact or fiction. The baroness tells her maid Annie that certain passages somehow remind her of Drake, who broke her heart. 
By coincidence, she is residing in the same hotel as Drake. He goes to see her, but she does not forgive him for leaving her without a word in Berlin. He explains that he was forced to leave suddenly, but she is not mollified.
Meanwhile, Drake instructs Burdge, his secretary, to send a cheque for £10,000 to the Buckingham Hospital for a new wing, even though Burdge informs him he is overdrawn at the bank. Drake tells him that the wealthy Mrs. Humbold's pearls will provide ample funds. The Humbolds are hosting a masquerade ball that night, and the baroness will be there.
At the ball, part of the entertainment is a group called the "Four Gangsters", who have been tied up and replaced by a gang of real gangsters, the same thieves from the aeroplane caper. Sculpie, their leader, kills an unarmed man who foolishly tries to resist. Afterward, however, Sculpie is furious to learn that the pearls he took from Mrs. Humbold are fakes. Once again, Drake has the real ones.

SOLUTION: What is the first name of the person who stole the diamonds?

PROBLEM: Passage: The song was performed during the Hard Candy Promo Tour and Sticky & Sweet Tour (2008–2009). At the promotional tour, "4 Minutes" was performed as the third song of the setlist. Madonna wore a shiny black outfit with black tails, Adidas track pants and high-heeled, lace-up boots for the performance. Justin Timberlake made an appearance alongside Madonna, at the Roseland Ballroom in New York, to perform the song. As Timbaland appeared on the video screens, the beat of the song started. The four side-stage video screens began to glide across the stage, and swiveled around to reveal Timberlake behind one and Madonna behind the other. They performed the song in a similar choreography from the music video.During the "4 Minutes" performance on the Sticky & Sweet Tour, Madonna wore a futuristic robotic outfit designed by Heatherette. She coupled it with metallic plates on her shoulder and a wig with long curled hair. Madonna and her dancers emerged from behind backdrops, on which Timbaland and Timberlake appeared, to perform their lines. An apparent duet between Madonna and Timberlake ensues, with Timberlake singing and dancing his part from the screens. He joined Madonna in person, for the show at Los Angeles's Dodger Stadium on November 6, 2008, the same show in which Britney Spears appeared alongside Madonna to perform "Human Nature". They performed "4 Minutes" in similar fashion to the promotional tour choreography. Timbaland sang his part of the song in person on November 26, 2008 at Dolphin Stadium in Miami Gardens, Florida. "4 Minutes" was also used as mashups during the performance of songs like "Vogue" and "Hung Up". On July 27, 2017, Madonna made a special appearance at Leonardo DiCaprio's annual fundraising gala, which took place on Saint-Tropez, France, and performed "4 Minutes" dressed in a green suit with feathers.

SOLUTION:
What were the full names of the people who performed the song in a similar choreography from the music video?
