question:
Question: In what year was the commander in chief who sent Elles to investigate the first tanks born? 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.

question:
Question: How old was the first confirmed non-English manager of Port Vale FC during peacetime? Passage:The first confirmed non-English manager during peacetime was Jock Cameron, who held the job for a year following World War I. Freddie Steele was a highly successful manager, who took the club to their second Third Division North title in 195354. In 1957 Scotsman Norman Low took the managerial reins, winning the Fourth Division title in 195859. The next manager of note was Sir Stanley Matthews, who was full-time manager for less than a year; his resignation followed a scandal involving players' pay. Widely considered to be the club's greatest ever manager, John Rudge led the "Valiants" to cup glory in 1993; his best success was the league however, securing three promotions in his sixteen-year reign. Bruno Ribeiro, from Portugal, became the first manager born outside of Britain to manage the club when he was appointed as manager in June 2016.

question:
Question: How old was the person who broke King's record in 1925? Passage:In April 1914 he joined Arsenal for a 1,000 fee, returning to League football. Arsenal had just missed out on promotion on goal average to the First Division, and in 191415 King spearheaded their attack, scoring 26 goals in the League and another three in the FA Cup. These included the first hat trick scored at their new Highbury stadium (against Grimsby Town on 14 November 1914), and two four-goal hauls against Wolverhampton Wanderers and Nottingham Forest. King's 29 goals that season were an all-time club record at the time, remaining so until Jimmy Brain broke it in 192526. However, Arsenal's defence let them down and they only finished fifth, outside of the promotion places; eventually, they were re-elected back to the First Division when football resumed after the end of the First World War.
