Example Input: Question: Which of the four expansion teams had the best record in their first year? Passage:In 1969, the Padres joined the ranks of Major League Baseball as one of four new expansion teams, along with the Montreal Expos (now the Washington Nationals), the Kansas City Royals, and the Seattle Pilots (now the Milwaukee Brewers). Their original owner was C. Arnholt Smith, a prominent San Diego businessman and former owner of the PCL Padres whose interests included banking, tuna fishing, hotels, real estate and an airline. Despite initial excitement, the guidance of longtime baseball executives, Eddie Leishman and Buzzie Bavasi as well as a new playing field, the team struggled; the Padres finished in last place in each of its first six seasons in the NL West, losing 100 games or more four times. One of the few bright spots on the team during the early years was first baseman and slugger Nate Colbert, an expansion draftee from the Houston Astros and still the Padres' career leader in home runs.

Example Input: Question: Who was the eldest of Liu's oath brothers? Passage:Liu Bei and his oath brothers Guan Yu and Zhang Fei swore allegiance to the Han Empire in the Oath of the Peach Garden and pledged to do their best for the people. However, their ambitions were not realised as they did not receive due recognition for helping to suppress the Yellow Turban Rebellion and participating in the campaign against Dong Zhuo. After Liu Bei succeeded Tao Qian as the governor of Xu Province, he offered shelter to Lu Bu, who had just been defeated by Cao Cao. However, Lu Bu betrayed his host, seized control of the province and attacked Liu Bei. Liu Bei combined forces with Cao Cao and defeated Lu Bu at the Battle of Xiapi. Liu Bei then followed Cao Cao back to the imperial capital, Xu, where Emperor Xian honoured him as his "Imperial Uncle". When Cao Cao showed signs that he wanted to usurp the throne, Emperor Xian wrote a secret decree in blood to his father-in-law, Dong Cheng, and ordered him to get rid of Cao. Dong Cheng secretly contacted Liu Bei and others and they planned to assassinate Cao Cao. However, the plot was leaked out and Cao Cao had Dong Cheng and the others arrested and executed along with their families.

Example Input: Question: Who was the elder of the two men De La Pole escaped from when he fled to France? Passage:He was appointed Chancellor in 1383, and created Earl of Suffolk in 1385, the first of his family to hold any such title (the earldom had become extinct in 1382 on the death of William de Ufford). However, in the late 1380s his fortunes radically altered, in step with those of the king. During the Wonderful Parliament of 1386 he was impeached on charges of embezzlement and negligence, a victim of increasing tensions between Parliament and Richard. He was the first official in English history to be removed from office by the process of impeachment. Even after this disgrace, he remained in royal favour, although soon fell foul of the Lords Appellant. He was one of a number of Richard's associates accused of treason by the Appellants in November 1387. After the Appellants' victory at Radcot Bridge (December 1387) and before the so-called Merciless Parliament met in February 1388, De La Pole shrewdly fled to Paris, thus escaping the fate of Sir Nicholas Brembre and Chief Justice Robert Tresilian. He remained in France for the remainder of his life. Sentenced in his absence, his title and estates were stripped from him.
