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. His responsibilities included its advanced training and tactical employment. He also commanded the large central depot and workshops established near Bermicourt.

In 1913 he was appointed a supervisor of school gardening, and pioneered several early initiatives in this area. During World War I he served with the 58th Battalion, and after the war he spent time in England studying horticulture. He ran a nursery at Noble Park from 1922. From 1928 to 1931 and 1937 to 1940 he was a member of Dandenong Shire Council, and he was also chairman of Associated Nurseries Pty Ltd from 1932 to 1965 and president of the Nurserymen and Seedsmen's Association from 1936 to 1937. In 1940 he was elected to the Victorian Legislative Council as a United Australia Party member for South Eastern Province. While in the Council he ran a Save the Forests campaign, which evolved into the National Resources Conservation League in which Isaac played a leading role. He lost Liberal and Country Party endorsement in 1952 and was defeated running as an independent candidate. In 1956 he was appointed an Officer of the Order of the British Empire. Isaac died at Footscray in 1965.

Question: Who was in charge of the Suez Canal Company when it was seized by the Egyptian government? Passage 1:It returned to racing in the 1961 season for the 12 Hours of Sebring, driven by Giancarlo Baghetti, Mairesse, Ginther and Wolfgang von Trips, finishing second overall behind teammates Phil Hill and Olivier Gendebien. At the Targa Florio it was team's sole front-engine entry, with Mairesse and Pedro Rodriguez driving. They retired after one of the drivers crashed during practice. 0780TR returned to the factory for repairs and modification of its nose to TRI/61 style. This was completed in time for the car to be run by the factory-supported North American Racing Team in the 1961 1000 km Nurburgring. Driven by Pedro Rodriguez and his younger brother Ricardo, the car finished second behind the Maserati Tipo 61 of Lloyd Casner and Masten Gregory. The Rodriguez brothers had to pit late in the race after destroying a front wheel, eliminating any chance of a win. The car then was entered by Scuderia Ferrari in the 1961 24 Hours of Le Mans, driven by Mairesse and Mike Parkes. After a poor start, they finished second, again behind Hill and Gendebien. They ran third for much of the race, achieving second when the Rodriguez brothers' 250 TRI61 retired with broken pistons with two hours to go. In the season-ending Pescara 4 Hours 0780TR was driven to victory by Scuderia Ferrari's Lorenzo Bandini and Giorgio Scarlatti, despite an oil leak that saw Bandini fall back to 27th. From this position, he regained second place with his rapid pace and won when the leading Camoradi Maserati Tipo 61 retired.
Passage 2:Nehru's foreign policy was the inspiration of the Non-Aligned Movement, of which India was a co-founder. Nehru maintained friendly relations with both the United States and the Soviet Union, and encouraged the People's Republic of China to join the global community of nations. In 1956, when the Suez Canal Company was seized by the Egyptian government, an international conference voted 184 to take action against Egypt. India was one of the four backers of Egypt, along with Indonesia, Sri Lanka, and the USSR. India had opposed the partition of Palestine and the 1956 invasion of the Sinai by Israel, the United Kingdom and France, but did not oppose the Chinese direct control over Tibet, and the suppression of a pro-democracy movement in Hungary by the Soviet Union. Although Nehru disavowed nuclear ambitions for India, Canada and France aided India in the development of nuclear power stations for electricity. India also negotiated an agreement in 1960 with Pakistan on the just use of the waters of seven rivers shared by the countries. Nehru had visited Pakistan in 1953, but owing to political turmoil in Pakistan, no headway was made on the Kashmir dispute.
Passage 3:The word stevedore originated in Portugal or Spain, and entered the English language through its use by sailors. It started as a phonetic spelling of estivador (Portuguese) or estibador (Spanish), meaning a man who loads ships and stows cargo, which was the original meaning of stevedore (though there is a secondary meaning of "a man who stuffs" in Spanish); compare Latin stipare meaning to stuff, as in to fill with stuffing. In the United Kingdom, people who load and unload ships are usually called dockers, in Australia dockers or wharfies, while in the United States and Canada the term longshoreman, derived from man-along-the-shore, is used. Before extensive use of container ships and shore-based handling machinery in the United States, longshoremen referred exclusively to the dockworkers, while stevedores, in a separate trade union, worked on the ships, operating ship's cranes and moving cargo. In Canada, the term stevedore has also been used, for example, in the name of the Western Stevedoring Company, Ltd., based in Vancouver, B.C., in the 1950s.

Question: How many years were there between the original release date of "Bizarre Love Triangle" and Frente!'s cover on a CD single? Passage 1:On 31 August 2012, Ferdinand signed for Peterborough United on a four-year contract for an initial fee of 200,000, which could rise to 500,000. He made his debut on 15 September 2012 in a 52 away defeat to Burnley. He went on to play 33 times for Peterborough in the Championship during the 201213 season, scoring once the winning goal in a 10 victory away to Blackpool on 16 March 2013. Peterborough were relegated to League One on the last day of the season, and Ferdinand fell out of first-team contention. He joined League Two club Northampton Town on 31 October 2013 on a one-month loan. After making five appearances at Northampton, impressing manager Aidy Boothroyd, his loan ended early on 28 November as he was recalled by Peterborough. Ferdinand played in three games for Peterborough following his recall, before being sent on loan for the rest of the season to Conference Premier leaders Luton Town on 3 January 2014. He made one substitute appearance in the league for Luton, as well as starting in the FA Trophy, before returning to Peterborough. Luton manager John Still stated that Ferdinand had "not done as well as I had hoped." In November 2014, Ferdinand joined Cheltenham Town on a two-month loan.
Passage 2:On March 18, 1965, a 33-year-old truck driver, Eugene P. Sesky, was on his way to deliver a load of bananas to Scranton, Pennsylvania. Sesky, an employee of Fred Carpentieroperator of a small truck line in Scrantonwas returning from the boat piers at Weehawken, New Jersey, where he had picked up his load. The load was destined for the locations in the "wholesale block" on the western edge of Lackawanna Avenue in Scrantoneither the local A&P Warehouse or to Halem Hazzouri Bananas, the premier banana seller in the area at the time. Sesky was driving a 1950s Brockway diesel truck tractor with a semi-trailer and was headed down Rt. 307 when he suddenly lost control. That section of Rt. 307 contains a two-mile descent extending from Lake Scranton to the bottom of Moosic Street that includes a drop in elevation of more than in less than . Sesky was unable to control the truck's speed down the hill due to a mechanical failure, variously attributed to the truck's brake system or its clutch. As a result, the truck cruised into Scranton at approximately , sideswiping a number of cars before it crashed into a house at the southwest corner of Moosic St and S. Irving Ave (), close to the bottom of the hill. Witnesses reported that Sesky did everything possible to avoid pedestrians and other motorists, including climbing out onto the truck's running board to try to warn people, and some have suggested that he may have deliberately flipped the truck over to avoid striking either bystanders or an automotive service station on Moosic Street that could have exploded in flames, causing a greater loss of life. Sesky was thrown from the truck and killed and bananas were spilled and strewn when the rig came to rest; 15 others were injured but only Sesky died. The road was closed for cleanup as Johnson's Towing Company helped out in the recovery. Trucks over 21,000 lb (10.5 t) are no longer allowed to travel that route (they must use Interstate 380 via Dunmore.)
Passage 3:Frente! (or Frente) are an Australian alternative rock and folk-pop group which originally formed in 1989. The original line-up consisted of Simon Austin on guitar and backing vocals, Angie Hart on lead vocals, Tim O'Connor on bass guitar (later replaced by Bill McDonald), and Mark Picton on drums (later replaced by Alastair Barden, then by Pete Luscombe). In August 1991 they issued their debut extended play, Whirled, which included the track, "Labour of Love". In March 1992 they released a second EP, Clunk, with its featured track, "Ordinary Angels", which peaked at No.3 on the ARIA Singles Chart. It was followed in October by "Kelly Street" (unintentional misprint of "Accidentally Kelly Street" was retained) which reached No.4. Their debut album, Marvin the Album, issued in November, peaked at No.5 on the ARIA Albums Chart. "Labour of Love" was released as an EP outside of Australasia in 1994 as a CD single with a cover version of New Order's "Bizarre Love Triangle" included. The Australian rock music historian Ian McFarlane felt that the group's "quirky, irreverent, acoustic-based sound was at odds with the usual guitar-heavy, grunge trends of the day. The band's presentation had a tweeness about it that could have been off-putting if not for its genuine freshness and honesty".
