Input: Consider 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 Lü Bu, who had just been defeated by Cao Cao. However, Lü Bu betrayed his host, seized control of the province and attacked Liu Bei. Liu Bei combined forces with Cao Cao and defeated Lü 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.

Input: Consider Input: Question: What was the population of the Commonwealth of the Philippines the last year Manuel Quezon served as the President of that place? Passage:Mestizos in the Philippines are traditionally a blend of Austronesian, Chinese, Spanish, Southern European or Latin American ancestry and are primarily descendants of viajeros (sailors who plied the Manila-Acapulco Galleon route), soldados (soldiers) and negociantes (merchants who were primarily Spanish, Chinese, or themselves mestizos). Because of this, most mestizos in the Philippines are concentrated in the urban areas and large towns of the islands such as Manila, Iloilo, Zamboanga, Cebu and Vigan. In these provinces of the Philippines, many Spaniards and foreign merchants intermarried with the rich and landed MalayoPolynesian local nobilities. From these unions, a new cultural group was formed, the mestizo class. Their descendants emerged later to become an influential part of the colonial government, and of the Principalía, among whom were Manuel L. Quezon, the first President of the Commonwealth of the Philippines (1935–1944); and Marcelo Azcárraga Palmero who even became interim Prime Minister of Spain on August 8, 1897 until October 4 of that same year. Azcárraga also went on to become Prime Minister of Spain again in two more separate terms of office. In 1904, he was granted Knighthood in the very exclusive Spanish chilvalric Order of the Golden Fleece — the only mestizo recipient of this prestigious award.
