Question: 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: Question: Which town where Missoni did work or showed their work was the largest? Passage:The business was founded in 1953, when Ottavio and Rosita Missoni set up a small knitwear workshop in Gallarate, Italy. They presented their first collection under the Missoni label in Milan in 1958. The business prospered, with the support of fashion editor Anna Piaggi, then at Arianna magazine. Rosita met the French stylist Emmanuelle Khanh in New York in 1965, which led to a collaboration and a new collection the following year. In April 1967, they were invited to show at the Pitti Palace in Florence. Rosita told the models to remove their bras, supposedly because they were the wrong color, and showed through the thin lame blouses. The material became transparent under the lights and caused a sensation. The Missonis were not invited back the following year, but the business grew; a new factory in Sumirago was built in 1969. Missoni designs were championed in the USA by Diana Vreeland, editor of American Vogue, and a Missoni boutique was opened in Bloomingdales.

Question: Question: How long had the Folger Shakespeare Library been standing the year Matus made his trip to England? Passage:Matus would read the history plays together with biographies of the kings they featured, and discovered, from earlier period tourist brochures, an article by A.L. Rowse and one by Louis Wright, past director of the Folger Shakespeare Library, that the artifacts and physical environment of Shakespeare's life were poorly represented. In 1983, impressed by reading a book on English architecture, he scoured the libraries to find information linking Elizabethan buildings to Shakespeare, only to find that virtually no good reference books had been written. After a brief trip to England for roughly 6 weeks in 1984, he and his brother Paul sold their home on Long Island, and Matus used his proceeds to finance his research project on this topic, which entailed a second 6-month journey in a camper vanto examine buildings on-site and interview archivists, preservationists, and historians. Returning to the United States in November 1985, he moved to Washington to finalize his research by reading in the Folger Library. There Samuel Schoenbaum, the doyen of Shakespearean biographers, assisted him in securing access to its restricted collections.
