Question: Who was the leader of Hungary during the Hungarian Revolution of 1848? Passage:The last meetings had revealed the rising antagonism with Britain and France, especially on Italian unification, the right to self-determination and the Eastern Question. The Alliance is conventionally taken to have become defunct with Alexander's death in 1825. France ultimately went her separate way after the July Revolution of 1830, leaving the core of Russia, Austria and Prussia as Central-Eastern European block which once again congregated to suppress the Revolutions of 1848. The Austro-Russian alliance finally broke up in the Crimean War: though Russia had helped to completely destroy the Hungarian Revolution of 1848, Austria did not take any action to support her ally, declared herself neutral and even occupied the Wallachian and Moldavian lands on the Danube upon the Russian retreat in 1854. Thereafter, Austria remained isolated, which added to the loss of her leading role in the German lands, culminating in the defeat of the Austro-Prussian War in 1866.

Question: How long did Paul Snyder own the Buffalo Braves before he sold the team to Brown Jr? Passage:The 197677 NBA season was the Braves seventh season in the NBA. The Braves were purchased by John Y. Brown, Jr., the former owner of the Kentucky Colonels in the now defunct American Basketball Association for $6.2 million. As part of an agreement with the Braves' former owner, Paul Snyder, Brown would give Snyder money received in player deals to reduce the purchase price. The sell-off began shortly after the season, as the Braves sold newly acquired Moses Malone. Malone was acquired in a trade with the Portland Trail Blazers after the ABA dispersal draft. Malone was now off to the Houston Rockets. The selling of players continued into the season as Bob McAdoo was sold to the New York Knicks. While the deals helped Brown pay virtually nothing for the franchise, it turned a promising franchise into a rebuilding one. Attendance fell off as the Braves finished in 4th place with a 30-52 record. The only spotlight was rookie Adrian Dantley, who captured Rookie of the Year honors with 20.3 points per game. However Dantley himself was traded following the season to the Indiana Pacers for Billy Knight.
