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.

Passage: Miklo is a man of Mexican and White American ethnicity who grew up in El Pico Aliso barrio in east Los Angeles. Upon moving back home from Las Vegas, Nevada, Miklo goes to stay with his two cousins Paco and Cruz. Miklo tells Cruz that he wants to join their gang Vatos Locos. While Paco is initially skeptical, Miklo later proves himself when he performs an attack on a rival gang, Tres Puntos. Afterwards he is made a member of Vatos Locos.
However, the Tres Puntos gang soon takes revenge by brutally attacking Cruz who is a budding artist, and damages his back for life. When Vatos Locos learn of the attack, they perform a well-planned counterattack. However, things go wrong when Miklo ends up getting shot by their rival gang's leader, "Spider". Miklo is able to shoot and kill Spider, but has to be rushed to the hospital by Paco while being chased by police. Paco crashes into another car at the El Pino tree and they are both arrested.
From here, the trio's paths diverges: Miklo is sent to San Quentin State Prison for murder, Paco volunteers for military service in the United States Marine Corps as an alternative choice to prison, and Cruz continues his passion for art. He also becomes a heroin addict due to the recurring back pain. His addiction leads to him being disowned by his family after his 12-year-old brother, Juanito, sees Cruz's needle next to him while he is passed out and naively decides to inject himself with it and dies from an overdose. Paco becomes an L.A.P.D. narcotics detective after leaving the Marine Corps.
Whose back is damaged for life?

Passage: The film is set in the home of a mad scientist called Professor Noodle. Professor Noodle has just developed a rejuvenation solution that reverses the aging process. Stan and Oliver are chimney sweeps and arrive to sweep the chimney. Oliver goes on to the roof and Stan stays below at the fireplace. Stan begins to shove the sweep up the chimney and knocks Oliver backwards and down through the skylight. Oliver comes back on to the roof and begins to pull the sweep up. Stan has hung on to the sweep and arrives at the roof. Oliver drops him back down through the chimney. Stan doesn't have enough extensions for the sweep and decides to use a rifle to shove the sweep the last part of the way. The gun goes off nearly shooting Oliver. Stan decides to go up to the roof and as he opens the skylight he knocks Oliver off the roof and down onto a greenhouse. Hardy finally falls down the chimney dislodging many bricks, sending a cloud of soot all over the living room and onto the butler, and damaging the piano. The butler says something about an electric chair, and stalks out. Stan and Oliver start to clean up the soot around the fireplace. They become distracted and Stan shovels the soot into Oliver's trousers.
Professor Noodle decides to test his rejuvenation solution. He puts a duck in a vat of water and adds a drop of his solution. The duck turns into a duckling. The professor is excited and decides to show Stan and Oliver his discovery. He puts another drop of his solution into the vat and the duckling turns into an egg. Stan and Oliver decide to test the solution for themselves when the professor leaves the room to fetch and rejuvenate the butler. Stan accidentally knocks Oliver and the solution into the vat. Oliver emerges as a chimpanzee. Despite being rejuvenatedde-evolved, eveninto a chimp by the massive overdose of the solution, he is able to say what he has said multiple times throughout, "I have nothing to say".
What does the person who became a chimpanzee do for a living?

Passage: The Mozarts' first London lodgings were above a barber's shop in Cecil Court, near St Martin-in-the-Fields. Letters of introduction from Paris proved effective; on 27 April 1764, four days after their arrival, the children were playing before King George III and his 19-year-old German queen, Charlotte Sophia. A second royal engagement was fixed for 19 May, at which Wolfgang was asked by the king to play pieces by Handel, Johann Christian Bach and Carl Friedrich Abel. He was allowed to accompany the queen as she sang an aria, and he later improvised on the bass part of a Handel aria from which, according to Leopold, he produced "the most beautiful melody in such a manner that everyone was astonished".Many of the nobility and gentry were leaving town for the summer, but Leopold reckoned that most would return for the king's birthday celebrations on 4 June, and accordingly organised a concert for the 5th. This was deemed a success, and Leopold hastened to arrange for Wolfgang to appear at a benefit concert for a maternity hospital on 29 June, at Ranelagh Pleasure Gardens. Leopold apparently saw this effort to support charitable works as "a way to earn the love of this very special nation". Wolfgang was advertised as "the celebrated and astonishing Master Mozart, a Child of Seven Years of Age..." (he was in fact eight), "justly esteemed the most extraordinary Prodigy, and most amazing Genius, that has appeared in any Age". On 8 July there was a private performance at the Grosvenor Square home of the Earl of Thanet, from which Leopold returned with an inflammation of the throat and other worrying symptoms. "Prepare your heart to hear one of the saddest events", he wrote to Hagenauer in anticipation of his own imminent demise. He was ill for several weeks, and for the sake of his health the family moved from their Cecil Court lodgings to a house in the countryside, at 180 Ebury Street, then considered part of the village of Chelsea.
What is the last name of the person who was asked by the king to play pieces by Handel, Johann Christian Bach and Carl Friedrich Abel?
