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.

Input: Consider Input: Passage: After leaving the army in January 1919, Grainger refused an offer to become conductor of the Saint Louis Symphony Orchestra and resumed his career as a concert pianist. He was soon performing around 120 concerts a year, generally to great critical acclaim, and in April 1921 reached a wider audience by performing in a cinema, New York's Capitol Theatre. Grainger commented that the huge audiences at these cinema concerts often showed greater appreciation for his playing than those at established concert venues such as Carnegie Hall and the Aeolian. In the summer of 1919 he led a course in piano technique at Chicago Musical College, the first of many such educational duties he would undertake in later years.Amid his concert and teaching duties, Grainger found time to re-score many of his works (a habit he continued throughout his life) and also to compose new pieces: his Children's March: Over the Hills and Far Away, and the orchestral version of The Power of Rome and the Christian Heart both originated in this period. He also began to develop the technique of elastic scoring, a form of flexible orchestration which enabled works to be performed by different numbers of players and instrument types, from small chamber groups up to full orchestral strength.In April 1921 Grainger moved with his mother to a large house in White Plains, New York. This was his home for the remainder of his life. From the beginning of 1922 Rose's health deteriorated sharply; she was suffering from delusions and nightmares, and became fearful that her illness would harm her son's career. Because of the closeness of the bond between the two, there had long been rumours that their relationship was incestuous; in April 1922 Rose was directly challenged over this issue by her friend Lotta Hough. From her last letter to Grainger, dated 29 April, it seems that this confrontation unbalanced Rose; on 30 April, while Grainger was touring on the West Coast, she jumped to her death from an office window on the 18th floor of the Aeolian Building in New York City. The letter, which began "I am out of my mind and cannot think properly", asked Grainger if he had ever spoken to Lotta of "improper love". She signed the letter: "Your poor insane mother".

Output: What is the name of the individual who jumped to her death from on office window on the 18th floor of the Aeollian building?

Input: Consider Input: Passage: When Stephen Herrick, a sedate, mild-mannered shipping magnate, loses his opera tickets, Mrs. Grange, the aggressive mother of his fiancee 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.

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

Input: Consider Input: Passage: Mary's (Elle Fanning) seemingly dull Christmas is suddenly filled with excitement and adventure following the arrival of her Uncle Albert, who gives her a Nutcracker as a gift. Later that night, Mary dreams that the Nutcracker called N.C. comes to life and takes her on a wondrous journey. They discover that the Nazi-like Rat King has usurped the Nutcracker's kingdom.
When Mary and N.C. go to the top of the Christmas tree, they meet a fairy and, as she begins to sing, N.C. looks at his hand, as it begins to turn human. Worried about this he runs into the sleigh, but leaves his human hand revealed, and Mary sees this. Mary, seeing this, goes to N.C. and rubs his hand as we see that he is in fact a human crying with tears of joy that he is human again. The snow fairy begins to sing and toys appear and begin to ice skate around the tree.
N.C. takes Mary to the top to show her his city. The two come up with a plan to shut down the smoke factory. Suddenly N.C. is starting to turn back in to a doll. Then the tree is shaking and Mary falls off, only to awake to being in her room.
Mary tries to tell her parents about it but they think she is not telling the truth. Later on in the movie N.C appears to have been killed, but Mary's tears and declaration of love restore him to life and transform him into a prince, his true form. The rats are all defeated and overthrown, but now Mary must reluctantly awaken from her dream. Before she is fully awake, N.C. promises that they will meet again. When Mary then goes to Uncle Albert's workshop she meets his new young neighbor, who is the exact image of the Nutcracker Prince and asks to be called N.C. The two become close friends, and the last shot of the film shows them ice skating together.
Output: What is the first name of the person that is given a nutcracker?
