Question: What country was the university Sadeq Tabatabaei got his doctorate from located in? Passage:In 1961, Sadegh Tabatabai went to Aachen to study biochemistry and later received his doctorate from the University of Bochum. While in Aachen, he organized a student group that campaigned against Shah Mohammad Reza Pahlavi. In 1967, he handled Ulrike Meinhof material about Iran, which was used in a famous column in Konkret magazine opposing the Shah's visit to West Germany that year. Tabatabai gave a speech at the grave of Benno Ohnesorg, an unarmed university student who was shot during a demonstration against the Shah's visit to the Deutsche Oper in Berlin by Karl-Heinz Kurras, a police officer later discovered to be an agent of the East German secret police, the Stasi.

Question: Who was the coach of the team Tony Craig played against in his first game in the first division? Passage:Born in Greenwich, London, Craig came through the youth ranks at Millwall. Adept as a central defender or a left back, he received his maiden call into the first team squad for a First Division league match against Bradford City on 5 April 2003 and was an unused substitute during the 1–0 win. Craig made his professional debut with a starting appearance in a 3–3 draw with Nottingham Forest on 26 April 2003 and lasted 67 minutes before being substituted for Robbie Ryan. He started in the final game of the 2002–03 season at home to Coventry City and scored the first senior goal of his career in the 2–0 win, with the opener on 51 minutes. Craig began the 2003–04 season as a virtual ever-present, making 10 appearances, but he dropped out of the squad entirely in October 2003. He was again out of favour with manager Dennis Wise during the 2004–05 season and had to wait until 19 February 2005 for his first appearance, which came with a start in a 1–0 defeat to Stoke City and he finished the campaign with 10 appearances.

Question: Who has been playing baseball longer between the pitcher who struck out Ryan Ludwick and the catcher who threw out Cristian Guzmán? Passage:In the eighth inning, Miguel Tejada singled, and with one out attempted to steal second base. Catcher Dioner Navarro made a poor throw to get Tejada, and the ball ended up in center field, allowing Tejada to advance to third base on the error. Tejada scored on a sacrifice fly by Adrián González, and the NL retook the lead. In the bottom half of the inning, after Brian Wilson retired the first two batters, Billy Wagner gave up a single to Grady Sizemore. Sizemore proceeded to steal second base (one of a record six stolen bases by both sides), and pinch-hitter Evan Longoria hit a ground rule double to left field to tie the game once again. With Mariano Rivera in to pitch with one out in the ninth inning for the American League, Rivera struck out Ryan Ludwick and Navarro threw out Cristian Guzmán as he attempted to steal second, thus ending the inning. Ryan Dempster struck out the side in the bottom of the ninth to force the game into extra innings.
