Problem: After the ceasefire following the Fall of France in June 1940, Alsace was annexed to Germany and a rigorous policy of Germanisation was imposed upon it by the Gauleiter Robert Heinrich Wagner. When, in July 1940, the first evacuees were allowed to return, only residents of Alsatian origin were admitted. The last Jews were deported on 15 July 1940 and the main synagogue, a huge Romanesque revival building that had been a major architectural landmark with its 54-metre-high dome since its completion in 1897, was set ablaze, then razed.
Who imposed the rigorous policy of Germanisation?

Answer: Gauleiter Robert Heinrich Wagner

Problem: DST's potential to save energy comes primarily from its effects on residential lighting, which consumes about 3.5% of electricity in the United States and Canada. Delaying the nominal time of sunset and sunrise reduces the use of artificial light in the evening and increases it in the morning. As Franklin's 1784 satire pointed out, lighting costs are reduced if the evening reduction outweighs the morning increase, as in high-latitude summer when most people wake up well after sunrise. An early goal of DST was to reduce evening usage of incandescent lighting, which used to be a primary use of electricity. Although energy conservation remains an important goal, energy usage patterns have greatly changed since then, and recent research is limited and reports contradictory results. Electricity use is greatly affected by geography, climate, and economics, making it hard to generalize from single studies.
Along with geography and economics, what variable often affects how much electricity an area uses?

Answer: climate

Problem: Early HDTV commercial experiments, such as NHK's MUSE, required over four times the bandwidth of a standard-definition broadcast. Despite efforts made to reduce analog HDTV to about twice the bandwidth of SDTV, these television formats were still distributable only by satellite.
Despite the reduced bandwith, HDTV format still had to be distributed how?
---
Answer:
by satellite
