QUES: In 1938 the Nazis altered about one-third of the toponyms of the area, eliminating, Germanizing, or simplifying a number of Old Prussian names, as well as those Polish or Lithuanian names originating from colonists and refugees to Prussia during and after the Protestant Reformation. More than 1,500 places were ordered to be renamed by 16 July 1938 following a decree issued by Gauleiter and Oberprasident Erich Koch and initiated by Adolf Hitler. Many who would not cooperate with the rulers of Nazi Germany were sent to concentration camps and held prisoner there until their death or liberation.

In what year was the Protestant Reformation started?
What is the answer?
ANS: unanswerable
QUES: The American Civil War boosted the local economy with wartime purchases of industrial goods, including that of the New Haven Arms Company, which would later become the Winchester Repeating Arms Company. (Winchester would continue to produce arms in New Haven until 2006, and many of the buildings that were a part of the Winchester plant are now a part of the Winchester Repeating Arms Company Historic District.) After the war, population grew and doubled by the start of the 20th century, most notably due to the influx of immigrants from southern Europe, particularly Italy. Today, roughly half the populations of East Haven, West Haven, and North Haven are Italian-American. Jewish immigration to New Haven has left an enduring mark on the city. Westville was the center of Jewish life in New Haven, though today many have fanned out to suburban communities such as Woodbridge and Cheshire.

What major war stimulated the New Haven economy by way of industrial goods purchased through the New Haven Arms Company?
What is the answer?
ANS: American Civil War
QUES: Resonant antennas are expected to be used around a particular resonant frequency; an antenna must therefore be built or ordered to match the frequency range of the intended application. A particular antenna design will present a particular feedpoint impedance. While this may affect the choice of an antenna, an antenna's impedance can also be adapted to the desired impedance level of a system using a matching network while maintaining the other characteristics (except for a possible loss of efficiency).

Which antenna type would be best for a project requiring a specific frequency?
What is the answer?
ANS:
Resonant antennas
