In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Example Input: Question: With what team did the player who threw out the runner initially sign out of high school? Passage:Both Blackburn and Danks held the game scoreless early on, allowing only six baserunners through the first four innings of the game. The Twins' Michael Cuddyer led off the top of the fifth with a double, the only Twins runner in scoring position for the entire game. Danks induced a deep flyball out from Delmon Young, which allowed Cuddyer to advance to third. Brendan Harris hit a deep flyball to center field which was caught for an out by Ken Griffey, Jr. Cuddyer tried to score on the ball as a sacrifice fly, but Griffey delivered an accurate throw to home plate and White Sox catcher A. J. Pierzynski blocked the plate and tagged out Cuddyer to end the inning. This play drew praise after the game as a "nice throw" and a "defensive gem".

Example Input: Question: How many people lived in Milan when Diocletian restored political stability after the Crisis of the Third Century? Passage:During the Crisis of the Third Century the Roman Empire nearly collapsed under the combined pressures of invasions, military anarchy and civil wars, and hyperinflation. In 284, emperor Diocletian restored political stability. He carried out thorough administrative reforms to maintain order. He created the so-called Tetrarchy whereby the empire was ruled by two senior emperors called Augusti and two junior vice-emperors called Caesars. He decreased the size of the Roman provinces by doubling their number to reduce the power of the provincial governors. He grouped the provinces into several dioceses (Latin: diocesis) and put them under the supervision of the imperial vicarius (vice, deputy), who was the head of the diocese. During the Crisis of the Third Century the importance of Rome declined because the city was far from the troubled frontiers. Diocletian and his colleagues usually resided in four imperial seats. The Augusti, Diocletian and Maximian, who were responsible for the East and West respectively, established themselves at Nicomedia, in north-western Anatolia (closer to the Persian frontier in the east) and Milan, in northern Italy (closer to the European frontiers) respectively. The seats of the Caesars were Augusta Treverorum (on the River Rhine frontier) for Constantius Chlorus and Sirmium (on the River Danube frontier) for Galerius who also resided at Thessaloniki.

Passage:As a freshman in 1998, Jackson played in 12 games, and was one of five true freshmen to play that season. He was a member of the Special teams and also played as reserve Defensive end. He recorded seven tackles with two quarterback pressures, a sack and a pass broken up. As a sophomore in 1999, he played in 12 games, and earned his first career start.

In 2000 as a junior, he was primarily a Defensive end, who also played Special teams, and he played in 12 games and started two. In the preseason, he was projected to be a starter, but was a backup to starter DeAngelo Lloyd at Left end, until Lloyd suffered a head injury against LSU, which forced Jackson to start against Georgia. For the season, he recorded 12 tackles, including four tackles-for-losses, two recovered fumbles and five quarterback hurries. He earned his second start of the season in the Cotton Bowl Classic, a game in which he recorded five tackles, including two for losses. As a senior in 2001, he played in 11 games, starting 10, missing one due to suspension for a violation of team rules. Prior to the regular season games against LSU, Jackson worked his way into the starting Left end position. His best game of the season came against Kentucky, in which he recorded eight tackles. For his career, he recorded 78 tackles, three fumble recoveries, five sacks and 10 tackles-for-losses.
