Question: Passage: Ferrary was the son of the Duke and Duchess of Galliera. His father, Raffaele de Ferrari, came from an ancient and rich family of Genovese bankers and was a wealthy businessman made Duke of Galliera in Genoa by Pope Gregory XVI, and Prince de Lucedio by Victor-Emmanuel II, King of Italy. Raffaele de Ferrari was co-founder of the Crédit Mobilier with the Péreire brothers, rivals of the Rothschilds, who financed many of the major construction projects of the second half of the 19th century: railroads in Austria, Latin America, Portugal, upper Italy and France (the Paris-Lyon-Marseille line), the digging of the Fréjus Rail Tunnel and the Suez Canal, and the reconstruction of Paris designed by Baron Haussmann. It is said that Raffaele de Ferrari died stuck in one of his immense safes.

Question: Passage: During Sherman's Atlanta Campaign in 1864, his Army Group was composed of the Army of the Tennessee, the Army of the Cumberland, and the Army of the Ohio. After the fall of Atlanta in September, Sherman sent the Army of the Ohio and the IV Corps of the Army of the Cumberland north to deal with the remnants of Lt. Gen. John Bell Hood's Army of Tennessee. Then, in November, he created the Army of Georgia, by combining the remaining XIV Corps and the XX Corps of the Army of the Cumberland. This new army, placed under the command of Maj. Gen. Henry Warner Slocum of the XX Corps, served as one of the two wings in Sherman's March to the Sea. The Army of the Tennessee, consisting of the XV and XVII Corps, commanded by Oliver O. Howard, served as the other wing. The Army of Georgia was involved in little fighting during the March to the Sea but was engaged in the Battle of Averasborough and bore the brunt of fighting at the Battle of Bentonville.

Question: Passage: The old moraine landscape of Lower Saxony emerged in the course of four great glacial advances of the Scandinavian ice sheet 350,000 to 130,000 years ago – one during the Elster glaciation and three during the Saale glaciation. The glacier of the most recent, Weichselian glaciation only reached the northeastern edge of the present Elbe valley depression, so that the existing terminal moraines beyond that point there were only affected periglacially, for example in the shape of solifluction over the frozen ground, by meltwater erosion and sediments or through wind-blown deposits of sand. The last two Saale glaciation advances in particular, the Drenthe II and the Warthe stadia, unfolded the East Hanonerian Terminal Moraine. It is therefore geomorphologically younger than the geest in western and central Lower Saxony, but clearly older than the young moraine landscapes in Mecklenburg-Vorpommern and Ostholstein (= Baltic Uplands).
