Problem: Roberto Mangabeira Unger (; born 24 March 1947) is a philosopher and politician. He has developed his views and positions across many fields, including social, political, and economic theory. In legal theory, he is best known by his work in the 1970s and 80s while at Harvard Law School as part of the Critical Legal Studies movement, which is held to have helped disrupt the methodological consensus in American law schools. His political activity helped the transition to democracy in Brazil in the aftermath of the military regime, and culminated with his appointment as Brazil's Minister of Strategic Affairs in 2007 and again in 2015.

The beginning of Unger's academic career began with the books Knowledge and Politics and Law in Modern Society, published in 1975 and 1976 respectively. These works led to the co-founding of Critical Legal Studies (CLS) with Duncan Kennedy and Morton Horwitz. The movement stirred up controversy in legal schools across America as it challenged standard legal scholarship and made radical proposals for legal education. By the early 1980s, the CLS movement touched off a heated internal debate at Harvard, pitting the CLS scholars against the older, more traditional scholars. Throughout much of the 1980s, Unger worked on his magnum opus, Politics: A Work In Constructive Social Theory, a three volume work that assessed classical social theory and developed a political, social, and economic alternative. The series is based on the premise of society as an artifact, and rejects the necessity of certain institutional arrangements. Published in 1987, Politics was foremost a critique of contemporary social theory and politics; it developed a theory of structural and ideological change, and gave an alternative account of world history. By first attacking the idea that there is a necessary progression from one set of institutional arrangements to another, e.g. feudalism to capitalism, it then built an anti-necessitarian theory of social change, theorizing the transition from one set of institutional arrangements to another. Unger devoted much of the following decades to further elaborating on the insights developed in Politics by working out the political and social alternatives. What Should Legal Analysis Become? (Verso, 1996) developed tools to reimagine the organization of social life. Democracy Realized: The Progressive Alternative (Verso, 1998) and What Should the Left Propose? (Verso, 2005) put forth alternative institutional proposals.

Problem: General Sir Miles Christopher Dempsey, (15 December 1896 - 5 June 1969) was a senior British Army officer who served in both world wars. As a junior officer, he fought in France during the First World War, where he was wounded, and served throughout the difficult interwar period, travelling to various corners of the globe. During the Second World War he had a close relationship with Bernard Montgomery and commanded the 13th Brigade in France in 1940, and spent the next two years training troops in England, before commanding XIII Corps for the invasions of Sicily and Italy in 1943. He later commanded the Second Army during the Battle of Normandy and made rapid advances in the subsequent campaign in Northern France and Belgium and was the first British Army commander to cross the Rhine.

After the end of World War II in Europe, Dempsey was appointed to the command of the British Fourteenth Army and GOC in C Malaya Command and then Land Force Commander, South East Asia. By the time he had arrived however, the war in the East was also over. Within his command were 123,000 British and Dutch prisoners and nearly 750,000 captured Japanese. Miles Dempsey, although modest and unassuming, was considered to be a highly competent officer. He asserted a very effective control over the British Second Army without taking the limelight. This was despite the stalemate in Normandy and the failure to advance beyond Antwerp and thus ensure that German forces remained isolated. He was claimed by military historian Carlo D'Este to be: A career infantryman, Dempsey was an ardent student of military history and during the interwar period had frequently visited Europe to study its battlefields firsthand. Blessed with an active and incisive mind, a phenomenal memory and a unique skill in reading maps, Dempsey would soon leave his army staff in awe over his ability to remember everything he saw on a map, to bring a landscape literally to life in his mind even though he had never actually seen it. This talent proved particularly important during the crucial battles around Caen in June and July 1944. Dempsey was considered the Eighth Army's best expert in combined operations and, as he grew in experience, Montgomery soon recognized his potential for army command. The two men shared many qualities, including a disdain for paperwork and a determination, based on their First World War experiences, never to waste their soldiers lives.

Problem: David Thompson was born in Westminster, Middlesex, to recent Welsh migrants David and Ann Thompson. When Thompson was two, his father died. Due to the financial hardship with his mother without resources, Thompson and his older brother were placed in the Grey Coat Hospital, a school for the disadvantaged of Westminster. Thompson graduated to the Grey Coat mathematical school, where he was introduced to basic navigation skills.

Thompson arrived in Churchill (now in Manitoba) and was put to work as a secretary, copying the personal papers of the governor of Fort Churchill, Samuel Hearne. The next year he was transferred to nearby York Factory, and over the next few years spent time as a secretary at Cumberland House, Saskatchewan, and South Branch House before arriving at Manchester House in 1787. During those years he learned to keep accounts and other records, calculate values of furs (It was noted that he also had several expensive beaver pelts at that time even when a secretary's job would not pay terribly well), track supplies and other duties. On 23 December 1788, Thompson seriously fractured his leg, forcing him to spend the next two winters at Cumberland House convalescing. It was during this time that he greatly refined and expanded his mathematical, astronomical, and surveying skills under the tutelage of Hudson's Bay Company surveyor Philip Turnor. It was also during this time that he lost sight in his right eye. In 1790, with his apprenticeship nearing its end, Thompson requested a set of surveying tools in place of the typical parting gift of fine clothes offered by the company to those completing their indenture. He received both. He entered the employ of the Hudson's Bay Company as a fur trader. In 1792 he completed his first significant survey, mapping a route to Lake Athabasca (where today's Alberta/Saskatchewan border is located). In recognition of his map-making skills, the company promoted Thompson to surveyor in 1794. He continued working for the Hudson's Bay Company until 23 May 1797 when, frustrated with the Hudson's Bay Company's policies over promoting the use of alcohol with indigenous people in the fur trade, he left. He walked 130 kilometres (80 mi) in the snow in order to enter the employ of the competition, the North West Company. There he continued to work as a fur trader and surveyor.
