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.

[Q]: 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".
[A]: What does the person who became a chimpanzee do for a living?

[Q]: Passage: During the 1750s Messiah was performed increasingly at festivals and cathedrals throughout the country. Individual choruses and arias were occasionally extracted for use as anthems or motets in church services, or as concert pieces, a practice that grew in the 19th century and has continued ever since. After Handel's death, performances were given in Florence (1768), New York (excerpts, 1770), Hamburg (1772), and Mannheim (1777), where Mozart first heard it. For the performances in Handel's lifetime and in the decades following his death, the musical forces used in the Foundling Hospital performance of 1754 are thought by Burrows to be typical. A fashion for large-scale performances began in 1784, in a series of commemorative concerts of Handel's music given in Westminster Abbey under the patronage of King George III. A plaque on the Abbey wall records that "The Band consisting of DXXV [525] vocal & instrumental performers was conducted by Joah Bates Esqr." In a 1955 article, Sir Malcolm Sargent, a proponent of large-scale performances, wrote, "Mr Bates ... had known Handel well and respected his wishes. The orchestra employed was two hundred and fifty strong, including twelve horns, twelve trumpets, six trombones and three pairs of timpani (some made especially large)." In 1787 further performances were given at the Abbey; advertisements promised, "The Band will consist of Eight Hundred Performers".In continental Europe, performances of Messiah were departing from Handel's practices in a different way: his score was being drastically reorchestrated to suit contemporary tastes. In 1786, Johann Adam Hiller presented Messiah with updated scoring in Berlin Cathedral. In 1788 Hiller presented a performance of his revision with a choir of 259 and an orchestra of 87 strings, 10 bassoons, 11 oboes, 8 flutes, 8 horns, 4 clarinets, 4 trombones, 7 trumpets, timpani, harpsichord and organ. In 1789, Mozart was commissioned by Baron Gottfried van Swieten and the Gesellschaft der Associierten to re-orchestrate several works by Handel, including Messiah (Der Messias). Writing for a small-scale performance, he eliminated the organ continuo, added parts for flutes, clarinets, trombones and horns, recomposed some passages and rearranged others. The performance took place on 6 March 1789 in the rooms of Count Johann Esterhazy, with four soloists and a choir of 12. Mozart's arrangement, with minor amendments from Hiller, was published in 1803, after his death. The musical scholar Moritz Hauptmann described the Mozart additions as "stucco ornaments on a marble temple". Mozart himself was reportedly circumspect about his changes, insisting that any alterations to Handel's score should not be interpreted as an effort to improve the music. Elements of this version later became familiar to British audiences, incorporated into editions of the score by editors including Ebenezer Prout.
[A]: What did Mozart hear in Mannheim?

[Q]: Passage: Released as the lead single from Pru, "Candles" was sent to rhythmic radio stations in the United States during the first week of September. Lott said the song was chosen as Pru's debut single as he felt that its allusions to the Miracles' song would appeal to listeners of all ages. It was further promoted by its inclusion on a back-to-school CD sampler from retailer Delia's. Director Dave Meyers shot the accompanying music video, which was released on November 25, 2000. The video premiered on MTV in February 2001, following roughly two months of rotation on BET. "Candles" reached number 68 on the Hot R&B/Hip-Hop Songs Billboard chart where it spent fourteen weeks, and peaked at number 65 on the R&B/Hip-Hop Airplay Billboard chart where it spent ten weeks. For both chart appearances, Billboard credited the song as appearing on The Sound of Style: Capital Records Fall 2000 Collection. Critical response to "Candles" was positive. David Dickinson, a music director at WHUR-FM, felt the single would be appropriate for radio and praised its production and Pru's voice. A writer from Billboard magazine complimented the lyrics and Pru's vocal performance, contrasting the artist's "cool, literate sensibility [against] the blatant sexual overtones" from other contemporary R&B female singers, but expressed doubt that hip-hop and mainstream R&B stations would play the song, seeing it as better suited for adult R&B radio."Aaroma" was released as the album's second single under the modified title "Aaroma (of a Man)". A writer from Billboard magazine compared its lyrics positively to those in Toni Braxton's "Un-Break My Heart" (1996). Another reviewer from the same publication singled out the track as one of the best from the album. According to a Billboard article published on June 16, 2001, dance and R&B remixes of the song were commissioned from Hani al-Badir and Carlos "Six July" Broady, respectively; the remixes were scheduled to be added to a re-release of the album. A music video for the single was filmed in June 2001. The song was also featured on the EMI-released album Celebrating Black Music Sampler 2001. Along with the two singles "Candles" and "Aaroma (of a Man)", the record was promoted as featuring "Smooth Operator" and "183 Miles".
