input question: Extract the answer to the question from the following context. Question: Who was the Emperor of Germany the first time that the Mongols invaded Eastern Europe after shattering the Kievan Rus' principalities? Context: During the early High Middle Ages, Germany was ruled by the Ottonian dynasty, which struggled to control the powerful dukes ruling over territorial duchies tracing back to the Migration period. In 1024, they were replaced by the Salian dynasty, who famously clashed with the papacy under Emperor Henry IV (r. 10841105) over church appointments as part of the Investiture Controversy. His successors continued to struggle against the papacy as well as the German nobility. A period of instability followed the death of Emperor Henry V (r. 111125), who died without heirs, until Frederick I Barbarossa (r. 115590) took the imperial throne. Although he ruled effectively, the basic problems remained, and his successors continued to struggle into the 13th century. Barbarossa's grandson Frederick II (r. 12201250), who was also heir to the throne of Sicily through his mother, clashed repeatedly with the papacy. His court was famous for its scholars and he was often accused of heresy. He and his successors faced many difficulties, including the invasion of the Mongols into Europe in the mid-13th century. Mongols first shattered the Kievan Rus' principalities and then invaded Eastern Europe in 1241, 1259, and 1287.???
output answer: Frederick II

input question: Extract the answer to the question from the following context. Question: Which is not a last name, Burke or Political? Context: Richard Hurd believed that Burke's imitation was near-perfect and that this defeated his purpose: an ironist "should take care by a constant exaggeration to make the ridicule shine through the Imitation. Whereas this Vindication is everywhere enforc'd, not only in the language, and on the principles of L. Bol., but with so apparent, or rather so real an earnestness, that half his purpose is sacrificed to the other". A minority of scholars have taken the position that, in fact, Burke did write the Vindication in earnest, later disowning it only for political reasons.???
output answer: political

Context: A second biotechnology district is being planned for the median strip on Frontage Road, on land cleared for the never-built Route 34 extension. As of late 2009, a Pfizer drug-testing clinic, a medical laboratory building serving Yale New Haven Hospital, and a mixed-use structure containing parking, housing and office space, have been constructed on this corridor. A former SNET telephone building at 300 George Street is being converted into lab space, and has been so far quite successful in attracting biotechnology and medical firms.???
