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: How was Joseph Coulon de Jumonville killed? Passage:The Ohio Country located between Britain's Thirteen Colonies and France's New France saw France and Britain clash. In 1753 the French sent an expedition south from Montreal that began constructing forts in the upper reaches of the Ohio River. In 1754 the Province of Virginia sent the Virginia Regiment led by George Washington to the area to assist in the construction of a British fort at present-day Pittsburgh, but the larger French force had driven away a smaller British advance party and built Fort Duquesne. Washington and some native allies ambushed a company of French scouts at the Battle of Jumonville Glen in late May 1754. In the skirmish the French envoy Joseph Coulon de Jumonville was left dead leading to a diplomatic incident. The French responded in force from Fort Duquesne, and in July Washington was forced to surrender at the Battle of Fort Necessity. Despite the conflict between them, the two nations were not yet formally at war.
