[EX Q]: Question: What were the factions in the 1975 civil war? Passage 1:The 84th Regiment of Foot (Royal Highland Emigrants) was a British regiment in the American Revolutionary War that was raised to defend present day Ontario, Quebec and Atlantic Canada from the constant land and sea attacks by American Revolutionaries. The 84th Regiment was also involved in offensive action in the Thirteen Colonies; including North Carolina, South Carolina, Georgia, Virginia and what is now Maine, as well as raids upon Lake Champlain and the Mohawk Valley. The regiment consisted of 2,000 men in twenty companies. The 84th Regiment was raised from Scottish soldiers who had served in the Seven Years' War and stayed in North America. As a result, the 84th Regiment had one of the oldest and most experienced officer corps of any regiment in North America. The Scottish Highland regiments were a key element of the British Army in the American Revolution. The 84th Regiment was clothed, armed and accoutred the same as the Black Watch, with Lieutenant Colonel Allan Maclean commanding the first battalion and Major General John Small of Strathardle commanding the second. The two Battalions operated independently of each other and saw little action together.
 Passage 2:By the mid-1970s, Arafat and his Fatah movement found themselves in a tenuous position. Arafat increasingly called for diplomacy, perhaps best symbolized by his Ten Point Program and his support for a UN Security Council resolution proposed in 1976 calling for a two-state settlement on the pre-1967 borders. But the Rejectionist Front denounced the calls for diplomacy, and a diplomatic solution was vetoed by the United States. In 1975, the increasing tensions between Palestinian militants and Christian militias exploded into the Lebanese Civil War, involving all factions. On 20 January 1976, the PLO took part in the Damour massacre in retaliation to the Karantina massacre. The PLO and Lebanese National Movement attacked the Christian town of Damour, killing 684 civilians and forcing the remainder of the town's population to flee. In 1976 Syria joined the war by invading Lebanon, beginning the 29‑year Syrian occupation of Lebanon, and in 1978 Israel invaded South Lebanon in response to the Coastal Road Massacre, executed by Palestinian militants based in Lebanon.

Passage 1:Bukhara was the last capital of the Emirate of Bukhara and was besieged by the Red Army during the Russian Civil War. During the Bukhara operation of 1920, an army of well-disciplined and well equipped Red Army troops under the command of Bolshevik general Mikhail Frunze attacked the city of Bukhara. On 31 August 1920, the Emir Alim Khan fled to Dushanbe in Eastern Bukhara (later he escaped from Dushanbe to Kabul in Afghanistan). On 2 September 1920, after four days of fighting, the emir's citadel (the Ark) was destroyed, the red flag was raised from the top of Kalyan Minaret. On 14 September 1920, the All-Bukharan Revolutionary Committee was set up, headed by A. Mukhitdinov. The government—the Council of People's Nazirs (see nāẓir)—was presided over by Faizullah Khojaev.

In August 1972 Grosheide announced that he would not stand for the election of 1972. The Cabinet Biesheuvel II was replaced by the Cabinet Den Uyl on 11 May 1973. Grosheide remained in active politics, in January 1974 he was nominated as Mayor of Rijswijk, serving from 1 February 1974 until his resignation on 1 July 1978.

Then Albert Bridge crosses to Datchet including at its lowest point, the thin island of Sumptermead Ait. On the Windsor side (right bank), the river winds round farmland at Princes Consort farm and Windsor Castle Home Park. There follows Victoria Bridge connecting the upper end of Datchet then a golf course, followed by Black Potts Railway Bridge. The railway bridge has a great brick pier in Black Potts Ait, behind which the Jubilee River rejoins the Thames. The left bank becomes playing fields of Eton College. The area known as Black Potts up to Romney Island is an attraction where those fishing have included Isaak Walton who wrote a major work which promoted angling and Charles II in the century before.

[EX Q]: Question: Of the other main contenders, who was the oldest? Passage 1:In 1955, he stood unsuccessfully as a Conservative candidate at the London County Council elections, in Islington East. At the 1959 general election he stood as Conservative candidate in Bristol South East, but he lost to the sitting Labour Member of Parliament Tony Benn (then known as Anthony Wedgwood Benn), whose majority was nearly 6,000 votes. However, in November 1960 Benn's father died and Benn inherited his peerage as Viscount Stansgate, with an automatic seat in the House of Lords. This disqualified Benn from sitting in the House of Commons, triggering a by-election on 4 May 1961. Benn, who wished to be allowed to disclaim his peerage, defied his inability to sit in the Commons by standing at the election, and he and St Clair were the only two candidates. St Clair's campaign displayed posters near every polling station warning voters that Benn was disqualified and that any votes for him would have no effect. Benn nevertheless won the election with nearly 70% of the votes and an increased majority of over 13,000. However, an Election Court considered what to do about the result, found that Benn was disqualified from being elected and that the voters were aware of this, and awarded the seat to St. Clair as the only duly qualified candidate. (At the time, St Clair was himself Master of Sinclair – heir presumptive (1957–1968) to his second cousin Charles St Clair, 17th Lord Sinclair, one of the representative peers for Scotland in the House of Lords.)
 Passage 2:A major proponent of representative government was Itagaki Taisuke, a powerful leader of Tosa forces who had resigned from his Council of State position over the Korean affair in 1873. Itagaki sought peaceful rather than rebellious means to gain a voice in government. Such movements were called The Freedom and People's Rights Movement. He started a movement aimed at establishing a constitutional monarchy and a national assembly. Itagaki and others wrote the Tosa Memorial in 1874 criticizing the unbridled power of the oligarchy and calling for the immediate establishment of representative government. Dissatisfied with the pace of reform after having rejoined the Council of State in 1875, Itagaki organized his followers and other democratic proponents into the nationwide Aikokusha (Society of Patriots) to push for representative government in 1878. In 1881, in an action for which he is best known, Itagaki helped found the Jiyūtō (Liberal Party), which favored French political doctrines. In 1882 Ōkuma Shigenobu established the Rikken Kaishintō (Constitutional Progressive Party), which called for a British-style constitutional democracy. In response, government bureaucrats, local government officials, and other conservatives established the Rikken Teiseitō (Imperial Rule Party), a pro-government party, in 1882. Numerous political demonstrations followed, some of them violent, resulting in further government political restrictions. The restrictions hindered the political parties and led to divisiveness within and among them. The Jiyūtō, which had opposed the Kaishintō, was disbanded in 1884, and Ōkuma resigned as Kaishintō president.
 Passage 3:Assert was then matched against older horses for the first time in Britain's most prestigious weight-for-age race, the King George VI and Queen Elizabeth Stakes over one and a half miles at Ascot Racecourse on 24 July. He started the 10/11 favourite ahead of his half-brother Bikala who had beaten a strong field in the Prix Ganay on his previous start. The other main contenders were Kalaglow, Height of Fashion and Glint of Gold. Assert went past Bikala on the turn into the straight and held off a strong challenge from Glint of Gold, but was caught inside the final furlong and beaten a neck by Kalaglow. On 17 August Assert was ridden by Pat Eddery in the eleventh running of the Benson and Hedges Gold Cup over ten and a half furlongs at York Racecourse. Starting the 4/5 favourite against six British-trained opponents, he took the lead from the start and pulled clear in the straight vo win easily by six lengths from Norwick. A month later, Assert started the 1/4 favourite for the Joe McGrath Memorial Stakes over ten furlongs. With Roche back in the saddle, he went eight lengths clear in the straight before being eased down to win by three lengths from Kind of Hush. Timeform described the race as being "little more than an exercise gallop" for the winner. On 3 October, Assert started 5/2 favourite for the Prix de l'Arc de Triomphe on very soft ground at Longchamp Racecourse. He was well-positioned turning into the straight but dropped away in the closing stage and finished eleventh of the seventeen runners behind Akiyda.
