The correct answer is D. The achievement of Manifest Destiny and the need for a "New American Frontier". The Manifest Destiny was an american philosphy from the 19th century that stated it was America's right, given by God, to expand and conquer other territories. In this period, imperialism was increasing at a global level and United States didn't want to be left behind of this imperalist race. The idea of the <em>New american frontier</em> was to expand the settled area as the first americans had started to do when they got to the new continet. The frontier had actually been changed by events like the Louisiana purchase but there was always a new frontier they wanted to reach. 
 
        
             
        
        
        
As a result of Shay's rebellion, a number of people, who had
previously opposed the idea, came over to the side that that the
United States needed a different type of government from the
Articles of Confederation. As a result they went along with the
idea for a Constitutional Convention. The constitutional convention
decided they needed a way for the National Government to act
against a rebellion when congress was not in session. Congress had
not been in session during Shay's Rebellion and no one could
authorize national military action against the rebellion. As a
result they made the President the Commander in Chief of the
Military Forces. The President would always be on duty. He could
always take action.
shays' rebellion? it showed the people that the us govt was willing
to use force when necessary to keep peace and 2 protect the
constitution. it also showed that if citizens wanted 2 change a
law, they had to do so peaceful.
I hope this helps.

Answer: C.Radio
Explanation:
Working alongside film was the most popular form of entertainment in the 1930s in America. The genres that were the most popular in that decade are comedy. This is because the country was in a significant economic crisis, and people were thus trying to divert their thoughts from the gloomy daily routine. As early as the early 1930s, over 40% of Americans owned radios, increasing that percentage year by year.
