Passage: Throughout the early years of the July Monarchy, Alkan continued to teach and play at public concerts and in eminent social circles. He became a friend of many who were active in the world of the arts in Paris, including Franz Liszt (who had been based there since 1827), George Sand, and Victor Hugo. It is not clear exactly when he first met Frédéric Chopin, who arrived in Paris in September 1831. In 1832 Alkan took the solo role in his first Concerto da camera for piano and strings at the Conservatoire. In the same year, aged 19, he was elected to the influential Société Académique des Enfants d'Apollon (Society of the Children of Apollo), whose members included Luigi Cherubini, Fromental Halévy, the conductor François Habeneck, and Liszt, who had been elected in 1824 at the age of twelve. Between 1833 and 1836 Alkan participated at many of the Society's concerts. Alkan twice competed unsuccessfully for the Prix de Rome, in 1832 and again in 1834; the cantatas which he wrote for the competition, Hermann et Ketty and L'Entrée en loge, have remained unpublished and unperformed.In 1834 Alkan began his friendship with the Spanish musician Santiago Masarnau, which was to result in an extended and often intimate correspondence which only came to light in 2009. Like virtually all of Alkan's correspondence, this exchange is now one-sided; all of his papers (including his manuscripts and his extensive library) were either destroyed by Alkan himself, as is clear from his will, or became lost after his death. Later in 1834 Alkan made a visit to England, where he gave recitals and where the second Concerto da camera was performed in Bath by its dedicatee Henry Ibbot Field; it was published in London together with some solo piano pieces. A letter to Masarnau and a notice in a French journal that Alkan played in London with Moscheles and Cramer, indicate that he returned to England in 1835. Later that year, Alkan, having found a place of retreat at Piscop outside Paris, completed his first truly original works for solo piano, the Twelve Caprices, published in 1837 as Opp. 12, 13, 15 and 16. Op. 16, the Trois scherzi de bravoure, is dedicated to Masarnau. In January 1836, Liszt recommended Alkan for the post of Professor at the Geneva Conservatoire, which Alkan declined, and in 1837 he wrote an enthusiastic review of Alkan's Op. 15 Caprices in the Revue et gazette musicale. 
Question: Whose cantatas written for the competition, Hermann et Ketty and L'Entrée en loge, have remained unpublished and unperformed?

Ex Output:
Alkan.

Passage: Three years after the destruction of the Death Star, the Rebel Alliance, led by Princess Leia, has set up a new base on the ice planet of Hoth. The Imperial fleet, led by Darth Vader, continues to hunt for the new Rebel base by dispatching probe droids across the galaxy. Luke Skywalker is captured by a wampa while investigating one such probe, but manages to escape from the wampa's lair with his lightsaber. Before Luke succumbs to hypothermic sleep, the Force ghost of his late mentor, Obi-Wan Kenobi, instructs him to go to Dagobah to train under Jedi Master Yoda. Han Solo locates Luke and cuts open the tauntaun he rode there on to keep his friend warm; they wait there until being rescued by a search party the next morning.
Meanwhile, the probe alerts the Imperial fleet to the Rebels' location. The Empire launches a large-scale attack using AT-AT walkers to capture the base, which forces the Rebels to retreat. Han and Leia escape with C-3PO and Chewbacca on the Millennium Falcon, but the ship's hyperdrive malfunctions. They hide in an asteroid field, where Han and Leia grow closer amidst tension and briefly kiss. Vader summons bounty hunters to assist in finding the Falcon. Luke, meanwhile, escapes with R2-D2 in his X-wing fighter and crash-lands on the swamp planet of Dagobah. He meets a diminutive creature who reveals himself to be Yoda; after conferring with Obi-Wan's spirit, Yoda reluctantly accepts Luke as his student. 
Question: Who is told to go train under Yoda?

Ex Output:
Luke.

Passage: Pre-election public-opinion polls had promised victory to the communists. Thus the total defeat of the PZPR and its satellite parties came as a surprise to all involved: after the first round of elections, it became evident that Solidarity had fared extremely well, capturing 160 of 161 contested Sejm seats, and 92 of 100 Senate seats. After the second round, it had won virtually every seat—all 161 in the Sejm, and 99 in the Senate.These elections, in which anti-communist candidates won a striking victory, inaugurated a series of peaceful anti-communist revolutions in Central and Eastern Europe that eventually culminated in the fall of communism.The new Contract Sejm, named for the agreement that had been reached by the communist party and the Solidarity movement during the Polish Round Table Talks, would be dominated by Solidarity. As agreed beforehand, Wojciech Jaruzelski was elected president. However, the communist candidate for Prime Minister, Czesław Kiszczak, who replaced Mieczysław Rakowski, failed to gain enough support to form a government.On June 23, a Solidarity Citizens' Parliamentary Club (Obywatelski Klub Parliamentarny "Solidarność") was formed, led by Bronisław Geremek. It formed a coalition with two ex-satellite parties of the PZPR — United People's Party and Democratic Party — which had now chosen to "rebel" against the PZPR, which found itself in the minority. On August 24, the Sejm elected Tadeusz Mazowiecki, a Solidarity representative, to be Prime Minister of Poland. Not only was he a first non-communist Polish Prime Minister since 1945, he became the first non-Communist prime minister in Eastern Europe for nearly 40 years. In his speech he talked about the "thick line" (Gruba kreska) which would separate his government from the communist past By the end of August 1989, a Solidarity-led coalition government had been formed. 
Question: What is the last name of the person who became the first non-Communist prime minister in Eastern Europe for nearly 40 years?

Ex Output:

Mazowiecki.
