 Passage 2: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.

Example Input: Question: What were jet fuel prices in 1975? Passage 1:In addition to withdrawing from the prestigious long-haul routes to New York and Los Angeles after only 18 months, other specific measures the airline took at the time to ensure its survival included dropping all scheduled flights to Belfast, Copenhagen, Gibraltar, Ibiza, Málaga, Palma de Mallorca and Tunis, indefinitely suspending scheduled services on the Glasgow—Southampton route as well as cutting the number of frequencies on the Gatwick—Glasgow and Gatwick—Edinburgh routes from six to four daily round trips. Two surplus aircraft were leased out to Air Malta and Austrian Airlines respectively for the duration of the 1975 summer timetable period. Another aircraft was stationed at West Berlin's Tegel Airport during the month of July of that year to fulfill a short-term charter contract to carry Turkish migrant workers to and from Istanbul on behalf of a local tour operator. BCal also decided to increase its 707 freighter fleet from one to four aircraft and to acquire a five-seater Piper Aztec to serve the rapidly growing executive charter market. These changes left BCal with 25 operational aircraft for the 1975 summer season. To reduce operating costs further, the airline decided to contract out its scheduled operations between Gatwick and Le Touquet to BIA. The reason for replacing BCal's One-Eleven 200 jet aircraft on this route with that airline's Herald turboprops at the beginning of the 1975 summer timetable period was the high price of jet fuel, which had made BCal's own jet aircraft operations uneconomic.
 Passage 2:A goalkeeper, Smeulders began his career as a youth with Orient. He was unable to displace the number 1 shirt from Ray Goddard and John Jackson and made just a handful of League Cup appearances before departing the Os in 1979. To revive his stalled career, Smeulders began the first of three spells with Bournemouth in 1979. After failing to break into the first team, Smeulders dropped into non-league football in January 1981 with Trowbridge Town, moving on to Weymouth and then back to Bournemouth in January 1984. This time he did establish himself in the first team, making 75 league appearances and setting a then-club record seven consecutive clean sheets, before moving to Torquay United in 1986. After failing to hold down a first team place and spending time away from Plainmoor on loan, Smeulders returned to Bournemouth for the third time in 1987. He again failed to hold down a regular place and dropped back into non-league football in 1989. Smeulders retired at age 38, due to a damaged knee.
 Passage 3:John Montagu was born in 1718, the son of Edward Montagu, Viscount Hinchingbrooke. His father died when John was four, leaving him as his heir. His mother soon remarried and he had little further contact with her. He succeeded his grandfather as Earl of Sandwich in 1729, at the age of ten. He was educated at Eton and at Trinity College, Cambridge, and spent some time travelling, initially going on the Grand Tour around Continental Europe before visiting the more unusual destinations of Greece, Turkey, and Egypt which were then part of the Ottoman Empire. This led him to later found a number of Orientalist societies. On his return to England in 1739, he took his seat in the House of Lords as a follower of the Duke of Bedford, one of the wealthiest and most powerful politicians of the era. He became a Patriot Whig and one of the sharpest critics of the Walpole government, attacking the government's strategy in the War of the Austrian Succession. Like many Patriot Whigs, Lord Sandwich was opposed to Britain's support of Hanover and strongly opposed the deployment of British troops on the European Continent to protect it, instead arguing that Britain should make greater use of its naval power. He gained attention for his speeches in parliament. His oratory earned him a reputation for clearly setting out his argument even if he lacked natural eloquence.
