[Q]: Passage: William "Bill" Boss, a psychopathic prison warden, watches the end of The Human Centipede 2 (Full Sequence) with his accountant, Dwight Butler. Bill says that he hates the films as his feet are massaged by his secretary, Daisy. Daisy replies that she enjoyed them. In response, Bill sucks his finger and inserts it into Daisy's vagina, telling her that women should not be allowed to voice their opinions. Dwight interrupts, attempting to pitch a "brilliant idea" to fix the prison's horrible retention and violence rates, but he is interrupted by a phone call.
Bill and Dwight are then summoned to the scene of an assault within the prison. One of the officers has been stabbed by an inmate. As punishment, Bill decides to stomp on the arm of the prisoner, exposing the bone and causing immense pain. He promises to do it again when his bones are healed.
Back in the Warden's office, Bill receives a mysterious package. After Dwight asks what it contains, Bill reveals that it is a jar of specially imported, dried African clitorises which he eats "for strength." After eating a few, he receives a threatening prank phone call from one of the inmates. Bill waterboards him with three buckets of boiling water, horribly disfiguring him. The inmate tells Bill that he has lost his soul.
Governor Hughes arrives immediately afterwards, ordering Bill and Dwight to put a stop to the violence and promising that they will both be fired otherwise. In anger and retaliation, Bill orders a 'mass castration' of the inmates, and castrates one of the prisoners himself. He covers his face in the blood of the inmate and later eats the cooked testicles for lunch, calling it "Energy Food." Daisy is forced to perform fellatio on Bill while Dwight is in the room. Upon completing the act, Daisy eats one of the dried clitorises, mistaking them for candy.
Question: What is the last name of the person who is interrupted by a phone call?
[A]: Butler.

[Q]: Passage: Nannerl herself was an apt pupil, no less quick to learn than her brother, and was playing the keyboard with striking virtuosity by the time she was eleven. In that year, 1762, Leopold brought the children to Munich to play before Maximilian III Joseph, Elector of Bavaria. Leopold then took the entire family to Vienna, on a trip that lasted for three months. He had secured invitations from several noble patrons, and within three days of arriving the children were playing at the palace of Count Collalto. Among those present was the Viennese Treasury councillor and future prime minister Karl von Zinzendorf, who noted in his diary that "a little boy, said to be only five-and-a-half years old [Wolfgang was actually nearly seven], played the harpsichord". After an appearance before the Imperial Vice-Chancellor, the Mozarts were invited to the royal court, where the Empress Maria Theresa tested Wolfgang's abilities by requiring him to play with the keyboard covered. During this court visit Wolfgang met the Archduchess Maria Antonia, the future Queen Marie Antoinette of France, who was two months his senior. Mozart's biographer Eric Blom recounts an anecdote of how the Archduchess helped Wolfgang when he slipped on the polished floor; she is supposed to have received a proposal of marriage in return.As the Mozarts began to be noticed by the Viennese aristocracy, they were often required to give several performances during a single day. They were well rewarded for this activityat the end of their first hectic week in Vienna, Leopold was able to send home the equivalent of more than two years' salary. Their schedule was interrupted when Wolfgang fell ill with scarlet fever, and their former momentum was not regained. Nevertheless, the visit left Leopold eager to pursue further opportunities for social and financial success. On their return to Salzburg, Wolfgang played the harpsichord and violin at a birthday concert for the archbishop, to the evident astonishment of those present.
Question: Who played the keyboard with striking virtuosity?
[A]: Wolfgang.

During this time, she ended her seven-year relationship with Jermaine Dupri.Several months later, Jackson performed a tribute to Michael at the 2009 MTV Video Music Awards, performing their duet "Scream".

For promotion, she performed a medley of hits at the American Music Awards, Capital FM's Jingle Bell Ball at London's O2 arena, and The X-Factor. The album's promotional single "Make Me", produced with Rodney "Darkchild" Jerkins, debuted in September. It became Jackson's nineteenth number one on the Hot Dance Club Songs chart, making her the first artist to have number-one singles in four separate decades.Later that month, Jackson chaired the inaugural benefit of amfAR, The Foundation for AIDS Research, held in Milan in conjunction with fashion week.
