Input: Consider Input: 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.

Input: Consider Input: Question: Which of the three emperors who Ji served lived longest? Passage:Jiang Ji (died 18 May 249), courtesy name Zitong, was an official and military general of the state of Cao Wei during the Three Kingdoms period of China. Born in the late Eastern Han dynasty, Jiang Ji started his career as a low-level official in his native Yang Province before becoming a subordinate of Cao Cao, the warlord who controlled the central government towards the end of the Eastern Han dynasty. After the end of the Eastern Han dynasty, he served in the state of Cao Wei through the reigns of the first three emperors Cao Pi, Cao Rui and Cao Fang and held various appointments in the military before rising to Grand Commandant, one of the top positions in the central government. During his service in Wei, he was known for being candid in giving advice to the emperor on various issues, including consolidating power, halting labour-intensive construction projects, and officials' abuses of power. In February 249, he joined the regent Sima Yi in staging a successful coup d'etat against his co-regent Cao Shuang, but died from illness a few months later.

Input: Consider Input: Question: In which election did Wilson receive more votes? Passage:Wilson was born near Creswick, Victoria. He worked variously as a blacksmith, wheelwright, and coachbuilder, living for periods in Melbourne and in Morwell. He served as president of the Victorian Coachbuilders' Union in 1901, and after moving to Western Australia in 1903 helped to re-establish a branch of the union there. At the 1904 state election, Wilson was elected to the seat of North Perth for the Labor Party, replacing George McWilliams. However, his time in parliament was short-lived, as he was defeated by James Brebber at the 1905 election. He later served on the North Perth Municipal Council from 1909 to 1914. In June 1919, Wilson contracted Spanish flu. He was placed into quarantine at Blackboy Hill, but died on the night of his arrival. Wilson had married Annie Andrew in 1887, with whom he had six children.
