Problem: In mid-June 1940, when international attention was focused on the German invasion of France, Soviet NKVD troops raided border posts in Lithuania, Estonia and Latvia. State administrations were liquidated and replaced by Soviet cadres, in which 34,250 Latvians, 75,000 Lithuanians and almost 60,000 Estonians were deported or killed. Elections were held with single pro-Soviet candidates listed for many positions, with resulting peoples assemblies immediately requesting admission into the USSR, which was granted by the Soviet Union. The USSR annexed the whole of Lithuania, including the Scheschupe area, which was to be given to Germany.
Who invaded the countries of Lithuania, Estonia and Latvia? 
The answer is the following: Soviet NKVD

Problem: Adherents of different religions generally disagree as to how to best worship God and what is God's plan for mankind, if there is one. There are different approaches to reconciling the contradictory claims of monotheistic religions. One view is taken by exclusivists, who believe they are the chosen people or have exclusive access to absolute truth, generally through revelation or encounter with the Divine, which adherents of other religions do not. Another view is religious pluralism. A pluralist typically believes that his religion is the right one, but does not deny the partial truth of other religions. An example of a pluralist view in Christianity is supersessionism, i.e., the belief that one's religion is the fulfillment of previous religions. A third approach is relativistic inclusivism, where everybody is seen as equally right; an example being universalism: the doctrine that salvation is eventually available for everyone. A fourth approach is syncretism, mixing different elements from different religions. An example of syncretism is the New Age movement.
What is one called that believes he has the one religion, but that the others aren't necessarily wrong?
The answer is the following: pluralism

Problem: Jehovah's Witnesses believe their highest allegiance belongs to God's kingdom, which is viewed as an actual government in heaven, with Christ as king. They remain politically neutral, do not seek public office, and are discouraged from voting, though individual members may participate in uncontroversial community improvement issues. Although they do not take part in politics, they respect the authority of the governments under which they live. They do not celebrate religious holidays such as Christmas and Easter, nor do they observe birthdays, nationalistic holidays, or other celebrations they consider to honor people other than Jesus. They feel that these and many other customs have pagan origins or reflect a nationalistic or political spirit. Their position is that these traditional holidays reflect Satan's control over the world. Witnesses are told that spontaneous giving at other times can help their children to not feel deprived of birthdays or other celebrations.
Why do Jehovah Witnesses forego religious holidays and birthdays or other celebrations?
The answer is the following: they consider to honor people other than Jesus

Problem: The newly invented Western Electric moving coil or dynamic microphone was part of the Wide Range System. It had a flatter audio response than the old style Wente condenser type and didn't require electronics installed in the microphone housing. Signals fed to the cutting head were pre-emphasized in the treble region to help override noise in playback. Groove cuts in the vertical plane were employed rather than the usual lateral cuts. The chief advantage claimed was more grooves per inch that could be crowded together, resulting in longer playback time. Additionally, the problem of inner groove distortion, which plagued lateral cuts, could be avoided with the vertical cut system. Wax masters were made by flowing heated wax over a hot metal disc thus avoiding the microscopic irregularities of cast blocks of wax and the necessity of planing and polishing.
How was the moving coil microphone unique to the Wente type?
The answer is the following:
didn't require electronics installed in the microphone housing
