Problem:Question: Which of the sons was born first? Passage 1:The regiment embarked for the West Indies in October 1826. It was initially based in Trinidad but moved to Barbados in January 1828, Antigua in January 1830 and Demerara and Berbice in February 1833. It embarked for home in March 1837. It returned to India in 1842 and saw action in Central India during the Indian Rebellion. It formed part of the force led by Major-General Sir Hugh Rose which besieged and captured Jhansi Fort in April 1858: four Victoria Crosses were awarded to members of the regiment for this operation. It returned home in August 1859 and was deployed to Gibraltar in 1864 and then went on to Mauritius in 1867 before returning to the Cape of Good Hope in 1870. It returned home in 1875 and then embarked for Bermuda in 1880.
 Passage 2: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.
 Passage 3:In addition to Shahrbanu, the historian Al-Masudi provides the names of four other children of Yazdegerd III; two sons, namely Peroz and Bahram, and two daughters, Adrag and Mardawand. While it was historically recorded that her brothers had escaped to the Tang emperor of China, Islamic traditions state that Shahrbanu's sisters were captured alongside her. One allegedly married Abdullah, son of the Caliph Umar, and became the mother of his son Salim, while another married Muhammad, son of the Caliph Abu Bakr, and became the mother of his son Qasim. Further alleged siblings have also been attributed to Shahrbanu, including Ghayanbanu, who was her full sister, Izdundad, who married the Jewish exilarch Bostanai, and Mihrbanu, who married Chandragupta, the Indian king of Ujjain.
