Q: Question: Which occured first, Ali's refusal to go to Vietnam or his being stripped of his championship? Passage:The fighters discuss their bouts against Muhammad Ali as well as their own lives and careers; Ali's fights against other opponents; his conversion to Islam and the assumption of the name Muhammad Ali; his relationship with the Nation of Islam organization (frequently referred to as the "black Muslims"), its leader, Elijah Muhammad (who bestowed Ali with his new name after he was briefly called Cassius X), and the Nation of Islam's most prominent minister, Malcolm X; Ali's refusal to be inducted into the United States Army to serve in the ongoing Vietnam War in 1967 on moral and religious grounds; the decision by the New York State Athletic Commission to strip him of his championship; his legal case and his reinstatement after the favorable June 28, 1970 decision by the Supreme Court of the United States. The Justices decided 8–0 (with Thurgood Marshall abstaining), that "... for the reasons stated, that the Department [of Justice] was simply wrong as a matter of law in advising that the petitioner's beliefs were not religiously based and were not sincerely held".

Q: Question: How many years had the American Revolution been ongoing when the British evacuated Boston? Passage:Benjamin Thompson was a Loyalist during the American Revolution, and fled the country in 1775 when the British evacuated Boston. He returned late in the Rev War commanding the King's American Dragoons, who saw action in the Southern states. He returned to England after the British surrender. He eventually settled for a time in the Holy Roman Empire, where he acquired the title of Count Rumford, and where he performed his groundbreaking research into the design of heating systems. This research resulted in a series of improvements to home heating systems, notably the Rumford stove, a shallow fireplace that more efficiently projected heat into a room than older and larger fireplaces. While in Munich, Thompson oversaw reforms of the indigent welfare system of Bavaria, and designed the city's famous English Garden. Thompson was also an inveterate and practical tinkerer, developing new versions of everyday utensils. He also proposed in 1799 the establishment in the United Kingdom of a research organization, which resulted in the founding of the Royal Institution. Although he never returned to the country of his birth, he did endow a professorial chair at Harvard College, and established the Rumford Prize, an annual award given by the American Academy of Arts and Sciences. He died in Paris in 1814.

Q: Question: Which ruler was in power longer, Radu I or Dan I? Passage:There is evidence that the Second Bulgarian Empire ruled at least nominally the Wallachian lands up to the Rucăr–Bran corridor as late as the late 14th century. In a charter by Radu I, the Wallachian voivode requests that tsar Ivan Alexander of Bulgaria order his customs officers at Rucăr and the Dâmboviţa River bridge to collect tax following the law. The presence of Bulgarian customs officers at the Carpathians indicates a Bulgarian suzerainty over those lands, though Radu's imperative tone hints at a strong and increasing Wallachian autonomy. Under Radu I and his successor Dan I, the realms in Transylvania and Severin continued to be disputed with Hungary. Basarab was succeeded by Nicholas Alexander, followed by Vladislav I. Vladislav attacked Transylvania after Louis I occupied lands south of the Danube, conceded to recognize him as overlord in 1368, but rebelled again in the same year; his rule also witnessed the first confrontation between Wallachia and the Ottoman Empire (a battle in which Vladislav was allied with Ivan Shishman). After the Magyar conquest (10-11th century), Transylvania had become an autonomous and multi-ethnic voivodeship led by a voivode appointed by the King of Hungary until the 16th century. Several Kings of Hungary invited settlers from Central and Western Europe, such as the Saxons, to come to Transylvania and occupy the region. The Szeklers were brought to southeastern Transylvania as border guards. Romanians are mentioned by the Hungarian documents (township called Olahteluk) in the 13th century (1283) in Bihar County. The "land of Romanians" (Terram Blacorum) appeared in Fogaras, and this area was mentioned under the name "Olachi" in 1285. After the collapse of the Hungarian Kingdom (following the disastrous Battle of Mohács, 1526) the region became the independent Principality of Transylvania until 1711.
