[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: What was the population of Réunion the year that Houellebecq was born? Passage:Houellebecq was born in 1956 on the French island of Réunion, the son of Lucie Ceccaldi, a French doctor born in Algeria of Corsican descent, and René Thomas, a ski instructor and mountain guide. He lived in Algeria from the age of five months until 1961, with his maternal grandmother. In a lengthy autobiographical article published on his website (now defunct), he states that his parents "lost interest in [his] existence pretty quickly", and at the age of six, he was sent to France to live with his paternal grandmother, a communist, while his mother left to live a hippie lifestyle in Brazil with her recent boyfriend. His grandmother's maiden name was Houellebecq, which he took as his pen name. Later, he went to Lycée Henri Moissan, a high school at Meaux in the north-east of Paris, as a boarder. He then went to Lycée Chaptal in Paris to follow preparation courses in order to qualify for grandes écoles (elite schools). He began attending the Institut National Agronomique Paris-Grignon in 1975. He started a literary review called Karamazov (named after Fyodor Dostoevsky's last novel) and wrote poetry.
