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.

[Q]: 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?
[A]: Pickering.


[Q]: Passage: Ferrier gave her first London recital on 28 December 1942 at the National Gallery, in a lunch-time concert organised by Dame Myra Hess. Although she wrote "went off very well" in her diary, Ferrier was disappointed with her performance, and concluded that she needed further voice training. She approached the distinguished baritone Roy Henderson with whom, a week previously, she had sung in Mendelssohn's Elijah. Henderson agreed to teach her, and was her regular voice coach for the remainder of her life. He later explained that her "warm and spacious tone" was in part due to the size of the cavity at the back of her throat: "one could have shot a fair-sized apple right to the back of the throat without obstruction". However, this natural physical advantage was not in itself enough to ensure the quality of her voice; this was due, Henderson says, to "her hard work, artistry, sincerity, personality and above all her character".
Ferrier's performances in the Glyndebourne run, which began on 12 July 1946, earned her favourable reviews, although the opera itself was less well received. On the provincial tour which followed the festival it failed to attract the public and incurred heavy financial losses.
By contrast, when the opera reached Amsterdam it was greeted warmly by the Dutch audiences who showed particular enthusiasm for Ferrier's performance. This was Ferrier's first trip abroad, and she wrote an excited letter to her family: "The cleanest houses and windows you ever did see, and flowers in the fields all the way!" Following her success as Lucretia she agreed to return to Glyndebourne in 1947, to sing Orfeo in Gluck's opera Orfeo ed Euridice. She had often sung Orfeo's aria Che farò ("What is life") as a concert piece, and had recently recorded it with Decca. At Glyndebourne, Ferrier's limited acting abilities caused some difficulties in her relationship with the conductor, Fritz Stiedry; nevertheless her performance on the first night, 19 June 1947, attracted warm critical praise.Ferrier's association with Glyndebourne bore further fruit when Rudolf Bing, the festival's general manager, recommended her to Bruno Walter as the contralto soloist in a performance of Mahler's symphonic song cycle Das Lied von der Erde. This was planned for the 1947 Edinburgh International Festival. Walter was initially wary of working with a relatively new singer, but after her audition his fears were allayed; "I recognised with delight that here potentially was one of the greatest singers of our time", he later wrote. Das Lied von der Erde was at that time largely unknown in Britain, and some critics found it unappealing; nevertheless, the Edinburgh Evening News thought it "simply superb". In a later biographical sketch of Ferrier, Lord Harewood described the partnership between Walter and her, which endured until the singer's final illness, as "a rare match of music, voice and temperament.". 
Question: What is the last name of the person who sang with Roy in Mendelssohn's Elijah?
[A]: Ferrier.


[Q]: Passage: Two pairs of friends, Matteo and Francesca & Shary and Diego, decide to spend the summer together in a beach house at the foot of Mount Circeo. Matteo,  a psychologist, is married to Francesca with whom he has a five-year-old girl, Elena. Diego and Shary have a less stable relationship, having a son together, David, who attends college in the United States. David comes to Italy for the first time in five years to spend time with his family and celebrate his birthday. Upon David's arrival, he and Matteo begin to develop feelings for each other. Only Leonard, Shary's brother, who has returned from his travels around the world to spend some time with the two pairs, seems to sense what is happening. The balance of Matteo's marriage begins to crack, and the growing tension seems to corrode the two families. While the rest of the household is out preparing for David's birthday party, Matteo goes to David's bedroom, and they have sex.  When Francesca returns, she has no front-door keys and enters the house through a patio door into David's room where she finds the two men having sex.  She runs out, and Matteo runs after her.  She dashes around a corner and into the street where she is hit and killed by a car. Later, Matteo, Shary, Diego, and David are having supper. Shary asks Matteo accusingly where he was at the time of the accident, and the movie ends as he begins to cry from guilt. 
Question: What are the names of everyone David is related to mentioned in the story?
[A]:
Diego.
