Article: Glacial moraines are formed by the deposition of material from a glacier and are exposed after the glacier has retreated. They usually appear as linear mounds of till, a non-sorted mixture of rock, gravel and boulders within a matrix of a fine powdery material. Terminal or end moraines are formed at the foot or terminal end of a glacier. Lateral moraines are formed on the sides of the glacier. Medial moraines are formed when two different glaciers merge and the lateral moraines of each coalesce to form a moraine in the middle of the combined glacier. Less apparent are ground moraines, also called glacial drift, which often blankets the surface underneath the glacier downslope from the equilibrium line.

Question: What are ground moraines also called?
Ans: glacial drift


Article: The Prussian Army was composed not of regulars but conscripts. Service was compulsory for all of men of military age, and thus Prussia and its North and South German allies could mobilise and field some 1,000,000 soldiers in time of war. German tactics emphasised encirclement battles like Cannae and using artillery offensively whenever possible. Rather than advancing in a column or line formation, Prussian infantry moved in small groups that were harder to target by artillery or French defensive fire. The sheer number of soldiers available made encirclement en masse and destruction of French formations relatively easy.

Question: What was the Prussian Army composed of, instead of regulars?
Ans: conscripts

Article: During a period of tough competition between mortgage lenders for revenue and market share, and when the supply of creditworthy borrowers was limited, mortgage lenders relaxed underwriting standards and originated riskier mortgages to less creditworthy borrowers. In the view of some analysts, the relatively conservative government-sponsored enterprises (GSEs) policed mortgage originators and maintained relatively high underwriting standards prior to 2003. However, as market power shifted from securitizers to originators and as intense competition from private securitizers undermined GSE power, mortgage standards declined and risky loans proliferated. The worst loans were originated in 2004–2007, the years of the most intense competition between securitizers and the lowest market share for the GSEs.

Question: Who policed mortgage originators and maintained relatively high standards prior to 2003?
Ans:
government-sponsored enterprises (GSEs)
