Question: Of the schools that Donegan attended, which is the oldest? Passage:Donegan was born on 13 July 1961 in Stirling, and educated at St Modan's High School in Stirling and at the University of Glasgow, where his musical career began. He was the bassist in The Bluebells, whose biggest hit was "Young at Heart", and Lloyd Cole and the Commotions. After the latter group split, Donegan became a journalist and an author. Between these roles, he worked as the House of Commons assistant to Brian Wilson MP. Whilst in that role, he was part of a one-off band called the Stop Its that recorded an anti-poll tax song of a similar name. The band also included David Hill, later press spokesman for Tony Blair. and Tim Luckhurst, who later became editor of The Scotsman newspaper, and is Professor of Journalism at the University of Kent. In the late 1980s, Donegan made a number of appearances with South London football team Belair Casuals FC. He is now a golf journalist for The Guardian, having previously worked at The Scotsman. He has held a post with the former publication since 2004, although he has been at the newspaper since 1994, as a general reporter and then as the Scotland correspondent from 1997 to 2004. During the 2010 Winter Olympics, Donegan gained notoriety for his overly critical reviews of the games. Journalists believed that his harsh reviews and similar critiques coming from the British media were made as an attempt to make the games look bad as the following Olympics would be held in London. In 2012, The Guardian made a tongue-in-cheek reference to the severe criticism of the prior Games by inviting a Canadian journalist to similarly critique the Summer Olympics in London as the 'worst ever'.

Question: Of the wars fought in the 1840s, how long did the longest one last? Passage:The Great Game began on 12 January 1830 when Lord Ellenborough, the President of the Board of Control for India, tasked Lord William Bentinck, the Governor-General, to establish a new trade route to the Emirate of Bukhara. Britain intended to gain control over the Emirate of Afghanistan and make it a protectorate, and to use the Ottoman Empire, the Persian Empire, the Khanate of Khiva, and the Emirate of Bukhara as buffer states between both empires. This would protect India and also key British sea trade routes by stopping Russia from gaining a port on the Persian Gulf or the Indian Ocean. Russia proposed Afghanistan as the neutral zone. The results included the failed First Anglo-Afghan War of 1838, the First Anglo-Sikh War of 1845, the Second Anglo-Sikh War of 1848, the Second Anglo-Afghan War of 1878, and the annexation of Kokand by Russia.
