Example Input: Question: What army did the USS Gunston Hall engage with during the assault on Kwajalein?  Passage:After intensive shakedown along the California coast Gunston Hall prepared to sail for the Western Pacific, where she was to participate in every major operation from February 1944 to the end of the war, 18 months later. Loading 225 men from the 4th Marine Tank Battalion and 2 amphibious units, as well as 15 LVTs, 15 tanks, 17 LCMs, and 15,000 gallons of gasoline, Gunston Hall departed San Diego on 13 January 1944. On D-Day for the assault on Kwajalein, 1 February 1944, she stood offshore to unload her cargo as the Marines stormed the beaches on Roi and Namur Islands. Gunston Hall remained in the area to repair small craft until 6 February, when she reembarked her former passengers and equipment and sailed to Guadalcanal via Funa Futi. The pattern she set here held for her participation in eight further key invasion efforts in the Pacific as the Navy "Island-hopped" marines and Army troops ever closer to the Japanese home islands.

Example Input: Question: Which of the universities was founded first, the one Howells first obtained a degree from, or the one he studied at thereafter? Passage:Howells was born on 11 May 1871 in Cwm, Monmouthshire in south Wales. He was educated at schools in Cwm and Pengam before winning a scholarship to Regent's Park Baptist College, London. After graduating with a degree awarded by the University of London, he studied at the University of Oxford (at Mansfield College and Jesus College), at Christ's College, Cambridge and at the University of Tübingen, obtaining degrees from a total of four universities. He travelled to India in 1895 for the Baptist Missionary Society to deal with literary and educational work. In 1907, he became Principal of Serampore College, a post he held until 1932. During this time, he also served as a Fellow and examiner of the University of Calcutta (1913 to 1929) and was a member of the Bengal Legislative Council in 1918. After returning to Britain in 1932, he was lecturer in Hebrew at Rawdon Baptist College until 1935. He received honorary degrees from the University of St Andrews, Serampore College and the University of Wales. During his retirement, he moved to Castleton, south Wales and he died on 7 November 1935.

Example Input: Question: Of the men who changed positions in Blackburn, which one graduated from high school later? Passage:Over the summer of 1995, Evans made the headlines by paying a British record fee for Nottingham Forest striker Stan Collymore. Many observers tipped Liverpool to win the Premier League title for that season, particularly as defending champions Blackburn had promoted Kenny Dalglish to Director of Football and appointed the less successful Ray Harford as manager, and runners-up Manchester United had sold three key players and surprisingly relied on young players to fill their place. Although Liverpool looked like contenders during the first stages of the season, the title race had effectively become a Newcastle United-Manchester United contest by Christmas, with Manchester United finally clinching the title. Liverpool, meanwhile, had to settle for third place in the league; any lingering hopes of title glory were finished off towards the end of April with a shock defeat by Coventry City. They did reach the FA Cup final, but lost 1–0 to a late Eric Cantona goal for Manchester United. As United had done the double, Evans and his exciting young team would be competing in the 1996–97 European Cup Winners' Cup. Nonetheless, their League position had improved from 4th to 3rd on the previous attempt. This had happened despite collecting only 71 points; however, the league notably had been reduced by 4 games that season. The 71 points was equivalent to 78.5 points the season before.
