Example input: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions.

Q: Question: Are the Eugene Emeralds based in Oregon? Passage:In August 2013, prior to Cease's senior year at Milton, Jonathan Mayo of MLB.com considered Cease to be a potential first-round draft choice in the upcoming 2014 MLB draft. Cease left a game during his senior season, on March 3, 2014, due to elbow soreness, which was later diagnosed as a partial tear of the ulnar collateral ligament (UCL) of the elbow in his pitching arm. As a result, he fell in the draft, and the Chicago Cubs selected him in the sixth round. He signed with the Cubs, receiving a $1.5million signing bonus, well above the $269,500 recommended at that slot. After he signed, he underwent Tommy John surgery to repair the UCL. He resumed throwing in May 2015, and pitched for the Arizona Cubs of the Rookie-level Arizona League. At the end of the 2015 season, Baseball America rated Cease as the second-best prospect in the Arizona League. He spent the 2016 season with the Eugene Emeralds of the Class A-Short Season Northwest League, where he posted a 20 winloss record with a 2.22 earned run average and 66 strikeouts in innings pitched.
