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?
Jerry.

Passage: Nannerl herself was an   apt pupil, no less quick to learn than her brother, and was playing the keyboard with striking virtuosity by the time she was eleven. In that year, 1762, Leopold brought the children to Munich to play before Maximilian III Joseph, Elector of Bavaria. Leopold then took the entire family to Vienna, on a trip that lasted for three months. He had secured invitations from several noble patrons, and within three days of arriving the children were playing at the palace of Count Collalto. Among those present was the Viennese Treasury councillor and future prime minister Karl von Zinzendorf, who noted in his diary that "a little boy, said to be only five-and-a-half years old [Wolfgang was actually nearly seven], played the harpsichord". After an appearance before the Imperial Vice-Chancellor, the Mozarts were invited to the royal court, where the Empress Maria Theresa tested Wolfgang's abilities by requiring him to play with the keyboard covered. During this court visit Wolfgang met the Archduchess Maria Antonia, the future Queen Marie Antoinette of France, who was two months his senior. Mozart's biographer Eric Blom recounts an anecdote of how the Archduchess helped Wolfgang when he slipped on the polished floor; she is supposed to have received a proposal of marriage in return.As the Mozarts began to be noticed by the Viennese aristocracy, they were often required to give several performances during a single day. They were well rewarded for this activity—at the end of their first hectic week in Vienna, Leopold was able to send home the equivalent of more than two years' salary. Their schedule was interrupted when Wolfgang fell ill with scarlet fever, and their former momentum was not regained. Nevertheless, the visit left Leopold eager to pursue further opportunities for social and financial success. On their return to Salzburg, Wolfgang played the harpsichord and violin at a birthday concert for the archbishop, to the evident astonishment of those present. 
Question: Who played the keyboard with striking virtuosity?
Wolfgang.

Passage: The film was written by Pulitzer Prize winner Ira Berkow, and narrated by actor Dustin Hoffman.  It was directed by Peter Miller, a documentary filmmaker known for his previous films A Class Apart, Sacco and Vanzetti, and The Internationale.Dustin Hoffman does not normally narrate films, and initially turned down the project.  But when he looked at the script, he changed his mind, saying: "Oh, this is about bigotry and overcoming anti-Semitism, about discrimination and these issues that I grew up with, that really matters to me".The film opens with a clip from the 1980 satirical comedy film Airplane!, in which a flight attendant is asked by a passenger if she has anything light to read.  She responds by offering an ultra-thin leaflet, saying:  "How about this leaflet, Famous Jewish Sports Legends?"The stereotype of Jews as non-athletic, as well as anti-semitism, are two issues that many Jewish baseball players faced and had to overcome.  Noted anti-semite Henry Ford wrote on May 22, 1920:  "If fans wish to know the trouble with American baseball they have it in three words—too much Jew."  A number of early Jewish ballplayers changed their names, so that it would not be apparent that they were Jewish.The movie discusses the key Jewish ballplayers in each decade since baseball started in the 1860s, and how that helped Jews assimilate and counteract the stereotype of Jews as cerebral but non-athletic.  The film is in part about Jewish immigration and assimilation into American society, bigotry against Jews, the passing on of Jewish traditions even during assimilation, heroism, and the breaking of Jewish stereotypes.Director Miller said:

At its heart, this is a film about overcoming stereotypes. Bigotry against Jews has faded a great deal ... 
Question: What is the name of the person that was know for The Internationale?

Peter Miller.
