Example Input: Question: What year was the national organization of the first fraternity at the University of Alabama founded? 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: How long had Mark Vaile held his post before resigning in 2008? Passage:The coalition total was reduced to 64 seats when Rob Oakeshott, former state Nationals turned independent MP, won the seat of Lyne at the September 2008 Lyne by-election, resulting from the resignation of former Howard minister and Nationals leader Mark Vaile. The April 2008 Gippsland by-election, resulting from the resignation of the former Howard minister and Nationals MP Peter McGauran, saw the Nationals' Darren Chester retain the seat, receiving a swing of 6%. The Liberals suffered a swing in the September 2008 Mayo by-election resulting from the resignation of former Howard minister and Liberal leader Alexander Downer, and came close to losing the seat to the Greens candidate. The Liberals retained seats at the Bradfield and Higgins by-elections in December 2009. The member for Ryan, Michael Johnson, was expelled from the Liberal National Party on 20 May 2010, reducing the Coalition to 63 seats.
