Question: What were the main groups involved in the event that resulted in the sacking of Constantinople in 1204? Passage:Papal calls for renewed holy war at the end of the twelfth century inspired not only the disastrous Fourth Crusade that sacked Constantinople in 1204, but also a series of simultaneous "Northern Crusades" that are less fully covered in English-language popular history, but which were more successful in the long run. Before the crusades, the region of Livonia was a mixed outpost, a pagan society where merchants from the Hanseatic League encountered merchants of Novgorod, and where Germanic, Scandinavian, and Russian trade, culture, and cults all mingled. The specific ethnic groups that intermingled and traded with the Germans, Danish, Swedish, and Russians here included the Wends, who were merchants from Lübeck, the Estonians, the Karelians, the Kuronians, the Lettgallians, the Semgallians (sometimes known as the Letts), the Livonians and the Lithuanians. The Western merchants would trade silver, textiles, and other luxury goods for furs, beeswax, honey, leather, dried fish, and amber. Livonia had been an especially promising location in terms of resources, and Arnold of Lübeck, in his Chronicle of the Slavs wrote that the land was "abundant in many riches" and was "fertile in fields, plentiful in pastures, irrigated by rivers", and "also sufficiently rich in fish and forested with trees".

Question: What age was John McCormack the year that DGOS was founded? Passage:The Dublin Grand Opera Society (DGOS) was founded in 1941 by Captain (later Colonel) William O'Kelly and a group of opera enthusiasts with John McCormack as its patron. The shows were cast with local singers and a volunteer chorus. Initially the music was provided by the orchestra of the Irish Army music school, and later by the Radio Eireann Symphony Orchestra. The Society put on two one-week seasons of opera throughout the years of World War II. After the war ended the DGOS presented performances by European opera companies such as the Opera-Comique, Hamburg Opera and the Netherlands Opera. From the mid 1950s to 1966, the Society, concentrated on Italian opera with the help of sponsorship from the Italian government. During that time numerous Italian stars and rising stars of the day appeared there, including Luciano Pavarotti who sang in Rigoletto, La traviata, and La bohème. The Italian sponsorship ended in 1966, but the Arts Council of Ireland and the Bord Fáilte (Ireland's tourist board) continued to provide guarantees for any financial losses. New opera companies were brought in, including the Romanian National Opera and the Prague National Theatre.

Question: Which of the two pitchers who combined to pitch three shutout innings had the most career no hitters? Passage:The Indians struck first off Marcus Stroman when Carlos Santana drew a leadoff walk in the first and scored on Mike Napoli's two out double, but their starter, Trevor Bauer had to leave the game in the bottom of the inning after allowing two walks and throwing 21 pitches due to a bloody pinkie finger as a result of being cut from a drone a few days earlier. Dan Otero in relief allowed a game-tying home run to Michael Saunders in the second. Napoli's home run in the fourth put the Indians back on top 2−1, but the Blue Jays tied it in the fifth off Zach McAllister when Ezequiel Carrera hit a leadoff triple and scored on Ryan Goins's groundout. Jason Kipnis's leadoff home run in the sixth gave the Indians a 3−2 lead. Stroman was taken out after walking Napoli with one out. Napoli moved to second on a wild pitch by reliever Joe Biagini and scored on José Ramírez's single to make it 4−2 Indians. Cody Allen and Andrew Miller combined to pitch three shutout innings, striking out five batters as the Indians took a 3–0 series lead.
