Question: What is the Black Watch? Passage 1:Thomson was born in Glasgow; soon after he was born his family realised that Glasgow was full of John Thomsons and started calling him Ian. He was educated at the High School of Glasgow and the University of Glasgow. In 1939 he joined the Black Watch but was able to finish his studies at Glagow University, graduating with a degree in economics in 1940. He had already applied to join the Colonial Service, did so in 1941 and was sent to Fiji, then a British colony, as aide-de-camp to the Governor, Sir Harry Luke. He was commissioned in the Fiji Military Forces and saw action in the Solomon Islands campaign. He was appointed a military "in recognition of gallant and distinguished services in the South West Pacific" in 1945. After the war he served the Administration of Fiji, becoming a District Officer and eventually District Commissioner 1963–66. In 1967 he reluctantly left Fiji to become Governor of the British Virgin Islands (BVI). He was appointed in the 1968 Birthday Honours. In 1971 he returned to Fiji after being invited by the Prime Minister of the newly independent Dominion of Fiji, Ratu Sir Kamisese Mara, to chair the board of the Fiji Sugar Corporation. He was also chairman of Fiji's airline, Air Pacific. He was knighted KBE in the 1985 New Year Honours on the advice of the Fijian government.
 Passage 2:In 1983 elections, N. T. Rama Rao came to power defeating the Indian National Congress. He praised the Naxalites for their patriotism before the elections. After coming to power, he demonstrated no significant change in government policy towards the revolutionary movement. Particularly after he was elected for a second time in 1985, his government put all its efforts to suppress the Naxalite movement in the state. Varavara Rao too was subjected to severe repression during this time. Six cases were foisted against him in 1985 alone. In July that year, along with functionaries of other people's organisations, he undertook an all India tour to make the people aware of the repression that was going on in Andhra Pradesh. After visiting Maharashtra, Madhya Pradesh, Bihar, West Bengal, New Delhi and Tamil Nadu, Varavara Rao returned to Andhra Pradesh in September to attend court cases. Dr. Ramanatham, a pediatrician and civil liberties activist was a close friend of Varavara Rao. While killing Dr. Ramanatham, and on several other occasions, police openly declared that killing Varavara Rao was their aim. With his life at risk, Varavara Rao could not discharge his duties as Secretary of Virasam and spokesperson of revolutionary literary movement. He was not able to move freely in Andhra Pradesh. Warangal has become a forbidden place for him. Armed and unarmed ruffians and police in civil clothes attacked his house on several occasions. Persecution against his friends in the movement was also mounted. Taking into consideration all these developments, Varavara Rao chose to cancel his bail in Secunderabad Conspiracy Case. On his request, his bail was cancelled and he was sent to jail on 26 December 1985.
 Passage 3:1973–74 was a big season for Newcastle United. The new attacking team put together by Harvey was being tipped to take one of the major honours come the season's end. By November Newcastle were second in the league, but they fell away to finish 15th, and in the League Cup they were knocked out in the third round. It was down to the FA Cup. Hendon were first up in the third round and a shock 2–2 draw at home meant that Newcastle had to go through a replay at Vicarage Road to see off the non-league side 3–0. Scunthorpe United were next up in the fourth round, and another shock 1–1 draw at St James' meant another replay against lower league opposition. Macdonald scored twice in the replay to crush Scunthorpe's hopes in a 3–0 win. The fifth round saw a difficult away draw to West Bromwich Albion, on a quagmire of a pitch and in front of the TV cameras. Newcastle were majestic, winning 3–0 with Macdonald scoring again. Newcastle faced Burnley at Hillsborough in the semi final. Macdonald scored two and Newcastle won 2–0; Harvey would sign Burnley defender Geoff Nulty for the next season after impressing in this game. Newcastle United were through to their first FA Cup final since 1955, where they would play Bill Shankly's Liverpool. Newcastle had a poor build up to final with preparations not going to plan: the tracksuit tops the players were meant to be wearing did not turn up, and they had to wear an unkind-looking purple outfit as they walked out at Wembley Stadium. Macdonald was the key man for Newcastle, having scored in every round for a total of eight goals in the competition. Liverpool played well and coasted to a 3–0 win with Kevin Keegan scoring twice. It was the end of an era for Harvey; the next season he signed Micky Burns and paid Sheffield Wednesday a club record £200,000 for Tommy Craig, but Newcastle could only finish a low 15th, despite getting some revenge on Liverpool, beating them 4–1 at St James' Park.
