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.

Question: What was the age difference between the 17th century Polish king and the person he helped regain Prussian in exchange for his support against Sweden? Passage 1:Corry cleared Bermuda on 25 October 1942 for Casablanca to participate in the Moroccan landings, in the screen of the aircraft carrier . She left Casablanca 16 November for Norfolk and Boston, and after overhaul resumed her coastal and Caribbean operations until 13 February 1943, when she sailed on escort duty from Norfolk for north Africa, returning 6 March for operations in the western Atlantic. On 11 August she sailed for Scotland and operated with the British Home Fleet, cruising once to Norway as providing escort for Ranger in the successful Allied air raid on Bodø, Norway in October 1943 (Operation Leader). Corry sailed twice to Iceland to cover the movement of Russia-bound convoys. Returning to Boston on 3 December, Corry sailed on 24 December for escort duty to New Orleans and Panama.
 Passage 2:The general outline of the Roman conquest of Britain during the 1st century AD is recorded by historical sources; for the involvement of specific forts historians depend on archaeological excavations. This part of Britain was occupied by a tribe known as the Cornovii. In AD 46–47 the Roman Army led by governor Aulus Plautius had probably occupied the lands to the south of the River Trent. Late in 47 the new governor of Britain, Ostorius Scapula, began a campaign against the tribes of the western mountains (modern Wales). Caratacus, their leader, was defeated in battle in AD 50 and fled to the Brigantes who occupied the Pennines. Their queen, Cartimandua, came to terms with the Romans and handed Caratacus over to them. Ostorius died and was replaced by Aulus Gallus who brought the Welsh borders under control but did not move further north or west. It was at about this time that the fort at Strutt's Park was built. It probably lay not far south of the border between Roman territory and that held by the Brigantes, who were now an allied or subject kingdom.
 Passage 3:The Duchy of Prussia was a duchy in the eastern part of Prussia from 1525–1701. In 1525 during the Protestant Reformation, the Grand Master of the Teutonic Knights, Albert of Hohenzollern, secularized the Prussian State of the Teutonic Order, becoming Albert, Duke in Prussia. His duchy, which had its capital in Königsberg (Kaliningrad), was established as a fief of the Crown of Poland, as had been Teutonic Prussia since the Second Peace of Thorn in October 1466. This treaty had ended the War of the Cities or Thirteen Years' War and provided for the Order's cession of its rights over the western half of its territories to the Polish crown, which became the province of Royal Prussia, while the remaining part of the Order's land became a fief of the Kingdom of Poland (1385–1569). In the 17th century King John II Casimir of Poland submitted Frederick William to regain Prussian suzerainty in return for supporting Poland against Sweden. On July 29, 1657, they signed the Treaty of Wehlau in Wehlau (Polish: Welawa; now Znamensk), whereby Frederick William renounced a previous Swedish-Prussian alliance and John Casimir recognised Frederick William's full sovereignty over the Duchy of Prussia. Full sovereignty was a necessary prerequisite for upgrading the Duchy to Kingdom of Prussia in 1701.
