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.

Question: What is the age difference between Cole's husband and the person who helped her recover from malaria? Passage:"Promise This" is an up-tempo dance-pop song written by American songwriter Priscilla Hamilton, British music producer Wayne Wilkins, who was responsible for Cole's debut single "Fight for This Love", and Christopher Jackson. It is written in the music key of C minor with a time signature in common time and a tempo of 151beats per minute. Cole's vocal range spans from G to E. The basic chord progression of the song is Cm, Cm, Cm, Cm, E, B, F, Cm, E, B and F. The song sees Cole singing some of the lyrics in French, referencing the children's song "Alouette". It was recorded in Santa Monica, California, and "finds her contemplating mortality with a cheerful morbidity, asking for prayers over a brutal march beat." Tabloids suggested that the lyrics were based upon her divorce from footballer Ashley Cole, and how her dancer friend Derek Hough nursed her to health while she was suffering from malaria. The Daily Star had also noted Cole's apparent affection in the song by her use of the French word alouette, meaning "skylark".
