Example Input: Question: How old was General Sir William Robertson when he selected Hugh Elles to liasise with troops? Passage:In August 1915, after recovering from his injuries, Elles was one of three officers specially selected by General Sir William Robertson, soon to be Chief of the Imperial General Staff (CIGS), the professional head of the British Army, to liaise with troops at the front and pass the information directly to the British General Headquarters (GHQ). In January 1916, as a General Staff Officer (GSO), Elles was sent by General Sir Douglas Haig, the Commander-in-Chief (C-in-C) of the BEF on the Western Front, to investigate the first tanks or "caterpillars" being built in England. He attended the first trials of "Mother" and reported back to Haig on its success. During the summer of 1916, he was tasked to report back from the Somme, where the tanks were first used. Elles was appointed to head the Heavy Branch (the first tank units) of the Machine Gun Corps in France on 29 September 1916, with the temporary rank of colonel. His responsibilities included its advanced training and tactical employment. He also commanded the large central depot and workshops established near Bermicourt.

Example Input: Question: How long had Christchurch been in existence for when Gould was born? Passage:Born in the Christchurch suburb of Fendalton on 19 October 1925, Gould came from a well-connected Canterbury family. His father was Derrick William Joseph Gould, a prominent businessman, racehorse owner and captain of the New Zealand polo team, and his mother was Elisabeth Mary Gould (nėe Elworthy). His paternal grandfather was George Gould, whose father, also called George Gould, was one of the founders in 1851 of the financial agents Gould Beaumont and Company that in 1919 amalgamated with two other firms to become Pyne Gould Guinness, one of New Zealand's largest stock and station agents. Other notable relatives on his father's side of the family include his father's cousin, the historian George Macdonald, and former British Labour MP Bryan Gould, who is a descendant of the elder George Gould. David's mother was a granddaughter of both Churchill Julius, the first Anglican Archbishop of New Zealand, and Edward Elworthy, an important landowner in South Canterbury. She was thus a first cousin of Charles Elworthy, Baron Elworthy, and niece of Sir George Julius and Awdry Julius.
