Problem: Given the question: Extract the answer to the question from the following context. Question: What party was Frederick II a part of? 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.

Problem: Given the question: Extract the answer to the question from the following context. Question: Archaeopteryx is part of what group? Context: The fossil record indicates that birds are the last surviving dinosaurs, having evolved from feathered ancestors within the theropod group of saurischian dinosaurs. True birds first appeared during the Cretaceous period, around 100 million years ago. DNA-based evidence finds that birds diversified dramatically around the time of the CretaceousPaleogene extinction event that killed off all other dinosaurs. Birds in South America survived this event and then migrated to other parts of the world via multiple land bridges while diversifying during periods of global cooling. Primitive bird-like dinosaurs that lie outside class Aves proper, in the broader group Avialae, have been found dating back to the mid-Jurassic period. Many of these early "stem-birds", such as Archaeopteryx, were not yet capable of fully powered flight, and many retained primitive characteristics like toothy jaws in place of beaks, and long bony tails.

The answer is:
Avialae

Problem: Given the question: Extract the answer to the question from the following context. Question: Not the first, but the more popular, where is that cemetary? Context: The largest cemetery is the Cementerio del Norte, located in the northern-central part of the city. The Central Cemetery (Spanish: Cementerio central), located in Barrio Sur in the southern area of the city, is one of Uruguay's main cemeteries. It was one of the first cemeteries (in contrast to church graveyards) in the country, founded in 1835 in a time where burials were still carried out by the Catholic Church. It is the burial place of many of the most famous Uruguayans, such as Eduardo Acevedo, Delmira Agustini, Luis Batlle Berres, Jose Batlle y Ordonez, Juan Manuel Blanes, Francois Ducasse, father of Comte de Lautreamont (Isidore Ducasse), Luis Alberto de Herrera, Benito Nardone, Jose Enrique Rodo, and Juan Zorrilla de San Martin.
