Article: A new delimitation of the federal territory keeps being debated in Germany, though "Some scholars note that there are significant differences among the American states and regional governments in other federations without serious calls for territorial changes ...", as political scientist Arthur B. Gunlicks remarks. He summarizes the main arguments for boundary reform in Germany: "... the German system of dual federalism requires strong Lander that have the administrative and fiscal capacity to implement legislation and pay for it from own source revenues. Too many Lander also make coordination among them and with the federation more complicated ...". But several proposals have failed so far; territorial reform remains a controversial topic in German politics and public perception.

Question: What does Gunlick remark that the German System of dual federalism requires strong Lander to have other than the capacity to implement legislation?
Ans: pay for it from own source revenues

Article: When the Federal Reserve makes a purchase, it credits the seller's reserve account (with the Federal Reserve). This money is not transferred from any existing fundsit is at this point that the Federal Reserve has created new high-powered money. Commercial banks can freely withdraw in cash any excess reserves from their reserve account at the Federal Reserve. To fulfill those requests, the Federal Reserve places an order for printed money from the U.S. Treasury Department. The Treasury Department in turn sends these requests to the Bureau of Engraving and Printing (to print new dollar bills) and the Bureau of the Mint (to stamp the coins).

Question: Who can freely withdraw from their reserve accounts at the Federal Reserve?
Ans: Commercial banks

Article: This principle is vitally important to understanding the behaviour of a quantity closely related to energy, called entropy. Entropy is a measure of evenness of a distribution of energy between parts of a system. When an isolated system is given more degrees of freedom (i.e., given new available energy states that are the same as existing states), then total energy spreads over all available degrees equally without distinction between "new" and "old" degrees. This mathematical result is called the second law of thermodynamics.

Question: What is entropy?
Ans: measure of evenness of a distribution of energy between parts of a system

Article: As a result of the magnitude 7.9 earthquake and the many strong aftershocks, many rivers became blocked by large landslides, which resulted in the formation of "quake lakes" behind the blockages; these massive amounts of water were pooling up at a very high rate behind the natural landslide dams and it was feared that the blockages would eventually crumble under the weight of the ever-increasing water mass, potentially endangering the lives of millions of people living downstream. As of May 27, 2008, 34 lakes had formed due to earthquake debris blocking and damming rivers, and it was estimated that 28 of them were still of potential danger to the local people. Entire villages had to be evacuated because of the resultant flooding.

Question: What formed behind blockages?
Ans:
quake lakes
