Example Input: Question: Of the 8 fraternities at the University of Alabama in the 1800s, which was the oldest on a national level? Passage:Greek letter organizations (GLOs) first appeared at the university in 1847 when two men visiting from Yale University installed a chapter of Delta Kappa Epsilon. When DKE members began holding secret meetings in the old state capitol building that year, the administration strongly voiced its disapproval. Over a few more decades, 7 other fraternities appeared at UA: Alpha Delta Phi in 1850, Phi Gamma Delta in 1855, Sigma Alpha Epsilon in 1856 (this was the founding chapter), Kappa Sigma in 1867, Sigma Nu in 1874, Sigma Chi in 1876, and Phi Delta Theta in 1877. Anti-fraternity laws were imposed that year, but were lifted in the 1890s. Women at the university founded the Zeta chapter of Kappa Delta sorority in 1903. Alpha Delta Pi soon followed.

Example Input: Question: Was Hubert Howe Bancroft alive when Cungagnaq died? Passage:Cungagnaq (; date of birth unknown - d. 1815) is venerated as a martyr and saint (as Peter the Aleut; ) by some jurisdictions of the Eastern Orthodox Church. He was allegedly a native of Kodiak Island (Alutiiq or Sugpiaq), and is said to have received the Christian name of Peter when he was baptized into the Orthodox faith by the monks of St Herman's missionaries operating in the north. He is purported to have been captured by Spanish soldiers near "San Pedro" and tortured and killed at the instigation of Roman Catholic priests either there or at a nearby location. At the time identified for his death, California was Spanish territory, and Spain was worried about Russian advances southwards from Alaska. Hubert Howe Bancroft, in his multi-volume History of California, only notes that, in connection with an incident wherein a Russian fur-hunting expedition was taken into custody after declining to leave San Pedro; one Russian source accused "the Spaniards of cruelty to the captives, stating that according to Kuskof’s report one Aleut who refused to become a Catholic died from ill-treatment received from the padre at San Francisco."
