[EX Q]: 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, Malaga, Palma de Mallorca and Tunis, indefinitely suspending scheduled services on the GlasgowSouthampton route as well as cutting the number of frequencies on the GatwickGlasgow and GatwickEdinburgh 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.

[EX Q]: Question: On what date did the Open 13 begin? Passage 1:During World War II it was one of the few cartridges used by both the Axis and Allied powers, a distinction it shared with the 919mm Parabellum pistol round. Apart from being the standard rifle cartridge of the German and Polish armed forces, it was also used by the armed forces of Great Britain in the Besa machine gun, which was mounted in some of their tanks and other armoured vehicles, as well as being extensively used by the Chinese, especially early in the war. After World War II it was used by the early Bundeswehr of West Germany. Later, when Egypt decided to manufacture the Hakim rifle, a licensed copy of the Swedish Ag m/42, they redesigned the breech to accept the 7.9257mm Mauser cartridge rather than use the original 6.555mm Ag m/42 cartridge. Its military use continues today (2012) in the former Yugoslavia in the Zastava M76 sniper rifle and the license-built copy of the MG 42, the M53 Sarac machine gun.

The centre-left alliance Italy Common Good obtained a clear majority of seats in the Chamber of Deputies, thanks to a majority bonus that has effectively trebled the number of seats assigned to the winning force, while in the popular vote it narrowly defeated the centre-right alliance of former Prime Minister Silvio Berlusconi. Close behind, the new anti-establishment Five Star Movement of comedian Beppe Grillo became the third force, clearly ahead of the centrist coalition of outgoing Prime Minister Mario Monti. In the Senate, no political group or party won an outright majority, resulting in a hung parliament. Speranza was elected to the Chamber of Deputies in Basilicata's electoral constituency.
