[EX Q]: Passage: Despite the grandeur of Florence, Etty was severely depressed, writing to his brother on 5 October that "I feel so lonely, it is impossible for me to be happy" and complaining of "the vermin in the bed, the dirt and the filth" which he considered "such as no Englishman can have any idea of, who has not witnessed it". His emotional state made it impossible for him to study, and within a month of his arrival in Italy, he began the journey back to England, stopping in Paris on 26 October 1816. There he enrolled in the atelier of Jean-Baptiste Regnault but found the atmosphere rowdy and the studio too full of Frenchmen, and he left after a week. While in Paris he also attended the Academie des Beaux-Arts, and amassed a large quantity of prints from the art shops of Paris. Still homesick, Etty left Paris, returning to London in November.Notwithstanding his unhappiness, Etty appears to have developed as a painter during his travels. For the first time, his two paintings exhibited at the 1817 Summer Exhibition (Bacchanalians: a Sketch and Cupid and Euphrosyne) attracted a favourable review in the press, in this case from William Paulet Carey writing in the Literary Gazette who considered Bacchanalians "a fine classical invention" and Cupid as showing "splendid promise". Carey was later to take great pride in being the first critic to recognise Etty's potential, and continued to champion him throughout his career. In 1818 Etty entered a copy of Damiano Mazza's The Rape of Ganymedeat the time thought to be by Titianin one of the Royal Academy's painting competitions. Easily the most accomplished entry in the competition, Etty was due to win until two of the other contestants complained that he had technically breached RA rules by briefly removing the painting from Academy premises to work on it at home; they further complained that Etty was technically a professional artist and thus ineligible for the contest despite his still being a student. Etty was disqualified from the competition, but the high quality of his work further raised his prestige within the Academy. Although his income was still low and he was surviving on gifts from his brother, at some point by 1818 Etty hired an assistant, George Henry Franklin.
Question: Where did Etty enroll in the atelier of Jean-Baptiste Regnault?
[EX A]: Paris.

[EX Q]: Passage: Tom is sleeping near the fireplace, and Jerry carefully sneaks past him. He goes up onto the dinner table and tries to reach for the food, but Tom attempts to slice him with a knife and he retreats, running up the staircase. Tom pulls the carpet off the staircase to catch Jerry, but also pulls down a large upright piano. While Jerry gets out of the piano's path, the piano crushes Tom to death. Tom's spirit ascends to the "Heavenly Express", a steam train that sends dead cats to Heaven.
Several cats are waiting to enter and the gatekeeper goes though their lives. The cats include Butch, who has lost a fight with a bulldog. Frankie, who was struck with a flat iron while singing on a backyard fence. Aloysius, who was run over and flattened by a steamroller. Even Fluff, Muff and Puff, a trio of kittens who were drowned after being thrown into a river. The gatekeeper allows them all through, as their deaths were untimely. However, he catches Tom trying to sneak past him to board the train and tells him to stand in line. The gatekeeper looks through his personal records and is disappointed by what he sees in it. Having learned that the main cause of Tom's death has been attributed to him persecuting "an innocent little mouse" all of his life and not from an accidental crushing of the piano, the gatekeeper refuses has entry to him for that action alone. He apologizes for this inconvenience, but the gatekeeper gives him a chance for a reprieve; should Tom have Jerry sign a certificate of forgiveness, he will be able to board the "Heavenly Express", which leaves in one hour. If he fails, Tom will be banished to hell where the hellhound devil awaits.
Question: Who is the innocent little mouse?
[EX A]: Jerry.

[EX Q]: Passage: Superstitious New York gambler Joe Baldwin, owner of the thoroughbred racing horse Sarcasm, believes that luck can be bought with charitable deeds. Before the Kentucky Derby, to "buy luck," he finances an expensive trip to Europe for gold-digger Jean Jason, his "good luck charm," not knowing she is taking her lover with her, gigolo and sometime artist Paul Vinette. He also gives his old friend Frank Brent cash to save his cab business and visits an orphanage in Louisville with his sister, where he meets Betty McKay, a pretty teacher who scoffs at his philosophy.
She scolds him for wishing for rain on the day of the Derby to aid his horse, who runs best on a muddy track, because the orphans plan an outdoor party. Although it rains as wished, Sarcasm loses the Derby, and Joe is convinced that it was because the orphans were pulling against him. In an attempt to repair the damage before the Preakness, Joe throws the orphans a lavish party, hiring clowns and other entertainment. To Betty's surprise, Joe is as excited as the children, and they fall in love.
After Sarcasm wins the Preakness, Joe returns to New York, where Jean is back from Europe. Joe tells her that he will not be seeing her any more because he is going to marry Betty, and she cajoles $50,000 from him as a final "luck insurance" payment. Before Joe shows up with the check, however, Paul arrives at Jean's apartment. They argue when he sees that she plans to run out on him with the money. Jean threatens him with a gun, and during a scuffle, kills her.
Question: What is the name of the horse that runs best on a muddy track?
[EX A]:
Sarcasm.
