[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
[A]: Yes

[Q]: Josie started planning her new garden in the winter. She chose flowers and vegetables that could grow in her area. She looked through the seed magazines. She ordered the tastiest kind of each vegetable and the prettiest kind of each flower. She talked to a friend about her plans. It seemed like the snow would never melt. But Josie didn't have to wait for spring to get started. Six weeks before the last frost, Josie planted seeds indoors. The tiny seedlings pushed up through the soil and began to grow. Finally spring arrived. Each day, Josie moved the seedlings outside for a few hours so they could get used to the cooler temperatures. Josie worked in her garden, digging the soil. She added a special growing mix from the garden store to make the soil better. When everything was ready, she removed the seedlings from their trays and planted them in her garden. The warm sun and rich soil helped her vegetables and flowers grow. <sep>When did Josie move the seedlings outside for a few hours so they could get used to the cooler temperatures?<sep>Weekdays

[Q]: Fossils give clues about major geological events. Fossils can also give clues about past climates. Fossils of ocean animals on the top of a mountain? Ocean animals have been found on the Earths tallest mountain. Its hard to believe, but it is true. These fossils were found at the top of Mt. Everest. Mt. Everest is the highest mountain on Earth. These fossils showed that this entire area was once at the bottom of a sea. It can only mean that Mt. Everest was uplifted. In fact, the entire Himalaya mountain range was raised. It was forced up from the collision of two continents. Fossils of plants are found in Antarctica. Now, Antarctica is almost completely covered with ice. Plants do not grow in Antarctica. According to fossils, they once did. This means that Antarctica was once much warmer than it is now. These fossils tell us about Antarcticas past climate. <sep>How do we know that Antarctica used to be warm?<sep>Plants can't live in Antartica
