[EX Q]: Question: Which of the three emperors who Ji served lived longest? Passage:Jiang Ji (died 18 May 249), courtesy name Zitong, was an official and military general of the state of Cao Wei during the Three Kingdoms period of China. Born in the late Eastern Han dynasty, Jiang Ji started his career as a low-level official in his native Yang Province before becoming a subordinate of Cao Cao, the warlord who controlled the central government towards the end of the Eastern Han dynasty. After the end of the Eastern Han dynasty, he served in the state of Cao Wei through the reigns of the first three emperors – Cao Pi, Cao Rui and Cao Fang – and held various appointments in the military before rising to Grand Commandant, one of the top positions in the central government. During his service in Wei, he was known for being candid in giving advice to the emperor on various issues, including consolidating power, halting labour-intensive construction projects, and officials' abuses of power. In February 249, he joined the regent Sima Yi in staging a successful coup d'état against his co-regent Cao Shuang, but died from illness a few months later.

[EX Q]: Question: How old was the president prior to Truman acceding to the president on 1945 when he died? Passage:Truman had acceded to the presidency in April 1945 after the death of Franklin D. Roosevelt. Defeating attempts to drop him from the ticket, Truman won the presidential nomination at the 1948 Democratic National Convention. The Democratic convention's civil rights plank caused a walk-out by several Southern delegates, who launched a third-party "Dixiecrat" ticket led by Governor Strom Thurmond of South Carolina. The Dixiecrats hoped to win enough electoral votes to force a contingent election in the House of Representatives, where they could extract concessions from either Dewey or Truman in exchange for their support. Truman also faced a challenge from the left in the form of former Vice President Henry A. Wallace, who launched the Progressive Party and challenged Truman's confrontational Cold War policies. Dewey, who was the leader of his party's moderate eastern wing and had been the 1944 Republican presidential nominee, defeated Senator Robert A. Taft and other challengers at the 1948 Republican National Convention.
