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.

 Passage 2:Leigh Lisker (December 7, 1918 – March 24, 2006) was an eminent American linguist and phonetician. Most of his career was spent at the University of Pennsylvania, where he was a professor and then emeritus professor of linguistics. Dr. Lisker received his A.B. in 1941, with a major in German, his M.A. in 1946, and a Ph.D. in 1949 in linguistics. He was a major figure in phonetics, working both at the University of Pennsylvania and at Haskins Laboratories in New Haven, CT, where he was a senior scientist from 1951 until the end of his life. He collaborated with several phoneticians, principally Arthur S. Abramson. He is best known for his work, done mostly in conjunction with Abramson, on voice onset time. Dr. Lisker also made important contributions to Dravidian linguistics, including the book Introduction to Spoken Telugu (Telugu), and did research comparing phonetic and phonological perceptions on the part of linguistically naive and linguistically sophisticated speakers of different native language backgrounds. He conducted such studies in collaboration with Dr. Abramson of the University of Connecticut, Bh. Krishnamurti  of University of Hyderabad, India, Adrian Fourcin  of University College London, and Mario Rossi  of the Institut de Phonétique at the Université de Provence, Aix-en-Provence.

After playing for New South Wales, he scored two tries in Australia's First Test win over New Zealand. By the end of the 1967 NSWRFL season he had scored sixteen tries, the most in the competition, before being selected to tour with the 1967-68 Kangaroos. Hanigan played in 11 games on tour but no Tests. With Manly-Warringah he reached the 1968 NSWRFL season's grand final and played on the wing in the loss to Souths.

 Passage 2:The Complete Compleat Enchanter is an omnibus collection of five fantasy stories by Ametican authors L. Sprague de Camp and Fletcher Pratt, gathering material previously published in three volumes as The Incomplete Enchanter (1941), The Castle of Iron (1950), and Wall of Serpents (1960), and represents an expansion of the earlier omnibus The Compleat Enchanter, which contained only the material in the first two volumes. The expanded version also differs from the previous omnibus by omitting its afterword, de Camp's essay "Fletcher and I". The omnibus is the first edition of the authors' Harold Shea series to be complete in one volume. It has appeared under three different titles. It was first published in the UK in paperback by Sphere Books in 1988 under the title The Intrepid Enchanter and with a foreword by Catherine Crook de Camp. The first US edition appeared under the title The Complete Compleat Enchanter, and replaces the foreword with a preface by David Drake. That edition was published by Baen Books in 1989, and has been reprinted a number of times since. Orion Books published an edition in the UK under the title The Compleat Enchanter in 2000 as volume 10 of their Fantasy Masterworks series. The stories in the collection were originally published in magazine form in the May 1940, August 1940 and April 1941 issues of Unknown, the June 1953 issue of Beyond Fantasy, and the October 1954 issue of Fantasy.
 Passage 3:Born in Berlin to very poor parents, Herz was destined for a mercantile career, and in 1762 went to Königsberg, East Prussia. He soon gave up his position as clerk and attended the University of Königsberg, becoming a pupil of Immanuel Kant, but was obliged to discontinue his studies for want of means. He thereupon became secretary to the wealthy Russian Ephraim, traveling with him through the Baltic Provinces. On August 21, 1770, he traveled from Berlin and acted as respondent when Kant presented his Inaugural dissertation at the University of Königsberg for the post of ordinary professor. In 1770 he had returned to Germany and studied medicine in Halle, where he became an MD in 1774, in which year he established himself in Berlin, being appointed physician at the Jewish hospital. Beginning in 1777, he delivered public lectures on medicine and philosophy, which were well attended by the students and the principal personages of the Prussian capital. At some of them even members of the royal family were present.
