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: Which ground did the Liverpool Football Club play at longer, Anfield or Goodison Park? Passage:Liverpool Football Club is an English association football club based in Liverpool, Merseyside, which competes in the top tier of English football, for the 2019–20 season. The club was formed in 1892 following a disagreement between the board of Everton and club president John Houlding, who owned the club's ground, Anfield. The dispute over rent resulted in Everton leaving Anfield for Goodison Park, which left Houlding with an empty stadium. Not content for his ground to lay idle, he created his own club: Liverpool. Liverpool joined the Lancashire League on their foundation before the 1892–93 season. They ended their inaugural season as league champions, and were elected to The Football League soon afterwards. The club remained in The Football League until 1992, when its First Division was superseded as English football's top level by the newly formed Premier League.
 Links: a. Goodison Park b. Anfield c. Liverpool F.C. d. Association football

Example Input: Question: Which of the cities which was a seat of the Second Continental Congress had a larger population? Passage:In the fall of 1777 forces of the British Army successfully captured Philadelphia, the seat of the Second Continental Congress, which was forced to relocate to York, Pennsylvania. The series of military setbacks (principally the losses at Brandywine in September and Germantown in October) caused many in the Continental Army and Congress to question George Washington's leadership of the war effort. In contrast, the northern army of General Horatio Gates had won a signal victory over John Burgoyne's forces, compelling Burgoyne to surrender his entire army after the Battles of Saratoga. Gates controversially claimed credit for the victory. Some historians feel that this was more due to the actions of Benedict Arnold, who, in the first battle on September 19, effectively and almost independently defended his forces against British assaults. It was also alleged that Gates had failed to provide Arnold with adequate reinforcements which would have turned the battle into an outright American victory, although there is not universal agreement on this matter. Gates was politically well connected to Congress. Some congressmen such as Richard Henry Lee, John Adams, and Samuel Adams wanted tighter Congressional control of the war effort and supported Gates. Although John Adams did not specifically call for Washington to be replaced, he worried that Washington was being made into a military idol, and was fearful of the effects of this upon republicanism. 
 Links: a. Samuel Adams b. Battles of Saratoga c. George Washington d. Philadelphia
Example Output: d

Example Input: Question: What year was the person who was the previous "most celebrated Padres call-up" before Rizzo born? Passage:Rizzo was called up to the majors after hitting .365 with an OPS of 1.159 along with 16 home runs and 63 RBI in 200 at-bats over 52 games in Tucson. The San Diego Union-Tribune called Rizzo "the most celebrated Padres call-up" since Roberto Alomar debuted with the team in 1988. Rizzo's promotion was prompted by the Padres' inadequate offensive production and fielding play of veterans at first base. In his debut on June 9, 2011, against the Washington Nationals, Rizzo struck out in his first at-bat, but then proceeded to hit a triple and score a run, helping the Padres to a 7–3 victory. He hit his first home run on June 11 against John Lannan. After three games he was 3-for-7 with a double, triple and a home run, while he demonstrated patience in drawing four walks for a .667 on-base percentage (OBP). On July 21, 2011 Rizzo was demoted back to Triple-A, and Blanks was promoted. Rizzo had struggled with only a .143 batting average and 1 home run, striking out 36 times in 98 at-bats. Hoyer said Rizzo "worked hard, never made excuses, and endeared himself to his teammates" during his initial stint in the majors. Rizzo was recalled to the majors on September 4 after finishing the season at Tucson batting .331 with 26 homers and 101 RBI in 93 games. He finished his first season in San Diego hitting only .141 with 46 strikeouts in 128 at-bats. Hoyer believed Rizzo would be the starting first baseman for the Padres in 2012 with Jesús Guzmán as the second option. However, Yonder Alonso moved ahead of Rizzo on the team's depth chart after he was acquired by the Padres in December 2011 in a trade for Mat Latos.
 Links: a. Roberto Alomar b. Yonder Alonso c. On-base percentage d. John Lannan
