Teacher: Now, understand the problem? Solve this instance: Question: Between the town where the field hospital was located and its nearest city, which one was established first? Passage 1:Chisholm and Knocker soon came to the conclusion that they could save more lives by treating the wounded directly on the front lines. In November, they decided to leave the corps and set up their own dressing station five miles east in a town named Pervyse, north of Ypres, just one hundred yards from the trenches. Here, in a vacant cellar which they named "Poste de Secours Anglais" ("British First Aid Post"), the two would spend the next three and a half years tending to the wounded. No longer affiliated with the Belgian Red Cross, they began acting completely as free agents and had to support their work by raising their own funds. Through sheer perseverance Knocker was able to arrange for the two of them to be officially seconded to the Belgian garrison stationed there. In January 1915, they were both decorated by King Albert I of Belgium with the Order of Léopold II, Knights Cross (with palm) for their courageous work on the front lines. They were also awarded the British Military Medal and both made Officers of the Most Venerable Order of St. John of Jerusalem. Chisholm was also decorated with the Queen Elisabeth Medal of Belgium and the British campaign medals, including the 1914 Star. The two became instant celebrities earning the distinction of being among the most photographed women of the war.
 Passage 2:Westonzoyland village is a little further to the west, near where the Battle of Sedgemoor was fought in 1685. The drain passes close to the village, and then turns to follow a more northerly course, with bridges carrying minor roads at Parchey, with Chedzoy slightly further west, and at Bawdrip, which is to the north-east of the Drain. At Crandon Bridge the A39 road crosses the Drain to a 'T'-junction with the old course of the A39 to Glastonbury and the newer A39 spur to the M5 motorway. Passing to the south of Puriton, it turns first west and then south-west as it passes under the M5 motorway, the Bristol and Exeter Railway, and the A38 road in quick succession, to reach the River Parrett at Dunball clyse.
 Passage 3:The poet colleagues shared a sense of Sturm und Drang and empathy, calling it the "Bündner Nachtigall" (Graubünden nightingale). Salis-Seewis returned to Switzerland in 1791, living in Chur and marrying there, on 26 December 1793, the 22-year-old Ursina v. Pestalozzi (Chur 29 September 1771 - Malans 27 June 1835). They had two sons; Johann-Ulrich Dietegan (Comte) v. Salis-Seewis (1794–1844) and Johann-Jakob (Freiherr) v. Salis-Seewis (1800–1881). He had a lively involvement in the political changes in his homeland over the next years lively involved, endorsed the alliance of the Three Leagues of Switzerland to the new France, and the proclaimed Helvetic Republic. After the area was occupied by Austria in the following year, Salis-Seewis and his family had to flee to Zurich. There, he was appointed inspector general of the Helvetican troops. This activity brought him the nickname "poet general". He later went to Bern and received a place on the Court of cassation. When the Act of Mediation was issued by Napoleon Bonaparte in 1803, it became possible for Salis-Seewis to return to Graubünden. There he held several public offices until 1817, then he withdrew as Swiss federal colonel. His father had died two years before.
