[EX Q]: Alexander II (Russian: Aleksandr II Nikolaevich, tr. Aleksandr II Nikolaevich; IPA: [aljI'ksandr fta'roj njIka'lajIvjItc]; 29 April [O.S. 17 April] 1818 in Moscow - 13 March [O.S. 1 March] 1881 in Saint Petersburg) was the Emperor of Russia from 2 March 1855 until his assassination in 1881. He was also the King of Poland and the Grand Duke of Finland. Alexander was the most successful Russian reformer since Peter the Great. His most important achievement was the emancipation of serfs in 1861, for which he became known as Alexander the Liberator (Russian: Aleksandr Osvoboditel', tr. Aleksandr Osvoboditel; IPA: [aljI'ksandr asv@ba'djitjIlj]). The tsar was responsible for numerous other reforms including reorganizing the judicial system, setting up elected local judges, abolishing capital punishment, promoting local self-government through the zemstvo system, imposing universal military service, ending some of the privileges of the nobility, and promoting the universities. Despite these reforms, during his reign, his brutal secret police, known as the Third Section, sent thousands of dissidents into exile in Siberia. In foreign policy, Alexander sold Alaska to the United States in 1867, fearing the remote colony would fall into British hands if there was another war. He sought peace, moved away from bellicose France when Napoleon III fell in 1871, and in 1872 joined with Germany and Austria in the League of the Three Emperors that stabilized the European situation. Despite his otherwise pacifistic foreign policy, he fought a brief war with Turkey in 1877-78, pursued further expansion into Siberia and the Caucasus, and conquered Turkestan. Although disappointed by the results of the Congress of Berlin in 1878, Alexander abided by that agreement. Among his greatest domestic challenges was an uprising in Poland in 1863, to which he responded by stripping that land of its separate Constitution and incorporating it directly into Russia. Alexander was proposing additional parliamentary reforms to counter the rise of nascent revolutionary and anarchistic movements when he was assassinated in 1881. <sep>Why is Alexander II called Aleksandr Osvoboditel?<sep>For his emancipation of serfs

[EX Q]: How would the universe look without gravity? It would have no planets and no stars. Thats how it looked when it was young. When the universe was young, there was only gas and dust. From this gas and dust, everything we now see was made. How were stars and planets created from just gas and dust? The answer is gravity. The same gravity that holds you down on Earth. The same force that causes your pencil to roll off your desk. The same force that causes it to fall to the floor. The invisible force of gravity caused dust and gas particles to be pulled together. This force is what formed all the objects in our solar system. This force formed the smallest moons. It also formed our Sun. This force caused more than just our solar system to form. It caused all the other solar systems to form. It caused the formation of all the galaxies of the universe. <sep>How would the universe look without gravity when it was young?<sep>Gas and dust particles
[EX A]: Yes

[EX Q]: The driver of the Facel Vega car, Michel Gallimard, who was Camus's publisher and close friend, also died in the accident. In August 2011, the Milan newspaper Corriere della Sera reported a theory that the writer had been the victim of a Soviet plot, but Camus's biographer, Olivier Todd, did not consider it credible. Camus was buried in the Lourmarin Cemetery, Lourmarin, Vaucluse, France. He was the second-youngest recipient, at the age of 44, of the Nobel Prize in Literature, after Rudyard Kipling, at the age of 42. He was survived by his wife and twin son and daughter, Jean and Catherine, who hold the copyrights to his work. Two of Camus's works were published posthumously. The first, entitled A Happy Death (1970), featured a character named Patrice Mersault, comparable to The Stranger's Meursault. There is scholarly debate as to the relationship between the two books. The second was an unfinished novel, The First Man (1995), which Camus was writing before he died. The novel was an autobiographical work about his childhood in Algeria. <sep>Who survived Camus after his death?<sep>His wife and twin son and daughter
