Question: During the Allied occupation of Germany after World War II, internal borders were redrawn by the Allied military governments. No single state comprised more than 30% of either population or territory; this was intended to prevent any one state from being as dominant within Germany as Prussia had been in the past. Initially, only seven of the pre-War states remained: Baden (in part), Bavaria (reduced in size), Bremen, Hamburg, Hesse (enlarged), Saxony, and Thuringia. The states with hyphenated names, such as Rhineland-Palatinate, North Rhine-Westphalia, and Saxony-Anhalt, owed their existence to the occupation powers and were created out of mergers of former Prussian provinces and smaller states. Former German territory that lie east of the Oder-Neisse Line fell under either Polish or Soviet administration but attempts were made at least symbolically not to abandon sovereignty well into the 1960s. However, no attempts were made to establish new states in these territories as they lay outside the jurisdiction of West Germany at that time.
Is there an answer to this question: When were attempts to abandon sovereignty made?

Answer: unanswerable

Question: An electromagnetic wave refractor in some aperture antennas is a component which due to its shape and position functions to selectively delay or advance portions of the electromagnetic wavefront passing through it. The refractor alters the spatial characteristics of the wave on one side relative to the other side. It can, for instance, bring the wave to a focus or alter the wave front in other ways, generally in order to maximize the directivity of the antenna system. This is the radio equivalent of an optical lens.
Is there an answer to this question: What changes the structuak traits of a wave on either side?

Answer: refractor

Question: An error sometimes made is the confusion of discussion regarding Greece's Eurozone entry with the controversy regarding usage of derivatives' deals with U.S. Banks by Greece and other Eurozone countries to artificially reduce their reported budget deficits.
