Question: Who coached the team that defeated Michigan in the National Championship Game of 2018? Passage 1:Following his father's relatively early death Heinrich Sproemberg went to live with his grandfather. It was now that he decided to concentrate his further academic studies on history. He attended the "Empress Augusta [secondary] school" ("Kaiserin-Augusta-Gymnasium" - as the "Ludwig-Cauer-Grundschule" was then known), and passed his school final exams ("Abitur") in 1909 which opened the way to a university education. He moved on to the Frederick William University (as the Humboldt was then known) where he studied History, and Jurisprudence. His teachers included , Michael Tangl and Otto Hintze. For his subsidiary module on Applied Economics he was taught by Gustav Schmoller. He received his doctorate in 1914 for work on the eleventh century Bishopric of Liege. The work was supervised by . However, after war broke out at the end of July 1914 there was a major falling out with Schafer. The German High Command implemented war plans that included a rapid invasion of Belgium which was accompanied by persistent reports of widescale atrocities by German troops against Belgian civilians. Sproemberg was at pains to distance himself from Schafer's "annexationist" support for German policy in respect of Belgium.

Passage 3:Strutt was baptised at Springfield, Essex, on 26 February 1762, the second son of John Strutt, of Terling Place, Essex, by Anne, daughter of the Rev. William Goodday of Maldon. Entering the army in 1778, he joined his regiment, the 61st, at Minorca. Later he was appointed to a company in the 91st, and took part in the defence of St. Lucia. In 1782, having exchanged into the 97th, he served at the siege of Gibraltar. On the signing of the preliminaries of peace he purchased a majority in the 60th regiment, and, being placed on half-pay, visited several German courts. In 1787 he was sent with his regiment to the West Indies, where he took an active part in military affairs. Succeeding to a lieutenant-colonelcy by special command of George III, he was removed to the 54th, and went with the army of Lord Moira to Flanders. In 1794 he bore a very distinguished part against the French at Tiel, going through much hard fighting. On his return he was sent to St. Vincent, where he was raised to the rank of brigadier-general. In January 1796, with two hundred men, he attacked a force of twelve hundred, being himself thrice wounded, and losing his right leg. On his return to England he was received with marked favour by the king, and on 23 February 1796 was made deputy governor of Stirling Castle, afterwards serving upon the staff in Ireland. On 23 June 1798 he was raised to the rank of major-general, and on 13 May 1800 he was, as a reward for his services, appointed to the sinecure office of governor of Quebec, and he held that post until his death. He died at Tofts, Little Baddow, Essex, on 5 February 1848, having seen an exceptional amount of military service, both at home and abroad.
