Question: 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.

Question: Question: Which country designed the fighter planes that the Yugoslav Air Force used but were badly maintained? Passage:An important portion of the 1999 war between Yugoslavia and the NATO coalition involved combat between the Yugoslav Air Force, which was the predecessor of today's Serbian Air Force, and the opposing air forces of NATO. United States Air Force F-15s and F-16s flying mainly from Italian air force bases attacked the defending Yugoslav fighters—usually MiG-29s, which were in bad shape, due to lack of spare parts and maintenance. A total of six Yugoslav MiG-29s were shot down in 1999, of which three were shot down by USAF F-15s, one by a USAF F-16, and one by a RNAF F-16. One aircraft, according to a Serbian documentary, was hit by friendly fire from the ground. Another four were destroyed on the ground. During the course of the air war, Yugoslav anti-aircraft defenses downed a USAF F-16C and an F-117 Nighthawk, the first stealth aircraft to ever be shot down in combat.
