Input: Consider Input: Question: Who was the president of University of Tennessee when Mike Smithson was a student? Passage:After attending the University of Tennessee, Smithson was selected by the Red Sox in the fifth round of the 1976 Major League Baseball Draft. During the course of his seven-year minor league apprenticeship, he participated in the longest baseball game in history between the Pawtucket Red Sox and Rochester Red Wings during the 1981 season. During the early morning hours of Sunday, April 19, 1981, he worked the full 15th, 16th and 17th innings, and got two outs in the 18th inning before turning the ball over to Win Remmerswaal. Smithson allowed two hits and three bases on balls in 3 innings pitched—but no runs. The game was suspended after 32 innings, and resumed June 23; Smithson's PawSox won it in the bottom of the 33rd frame.

Input: Consider Input: Question: What is the birth year of the Field Marshal who provided Manstein with massive air support? Passage:As the German Sixth Army was encircled in Stalingrad, the Red Army undertook a series of wider attacks against the rest of Army Group South. These culminated on 2 January 1943 when the Red Army launched Operation Star and Operation Gallop, which between January and early February broke German defenses and led to the Soviet recapture of Kharkov, Belgorod, Kursk, as well as Voroshilovgrad and Izium. The Soviet victories caused participating Soviet units to over-extend themselves, though this was largely due to Manstein's strategy of controlled retreat towards the Dneiper. Freed on 2 February by the surrender of the German Sixth Army, the Red Army's Central Front turned its attention west and on 25 February expanded its offensive against both Army Group South and Army Group Center. Months of continuous operations had taken a heavy toll on the Soviet forces and some divisions were reduced to 1,000–2,000 combat effective soldiers. On 19 February, Field Marshal Erich von Manstein launched his Kharkov counterstrike, using the fresh II SS Panzer Corps and two panzer armies. Manstein benefited greatly from the massive air support of Field Marshal Wolfram von Richthofen's Luftflotte 4, whose 1,214 aircraft flew over 1,000 sorties per day from 20 February to 15 March to support the German Army, a level of airpower equal to that during the Case Blue strategic offensive a year earlier.
