I am assuming that you mean in WW2. If so it change the face of Europe because other countries saw them as a threat and the threat would increase overtime. People didn't want to come to Europe especially with those two kind of government, Fascist and National Socialism many were scared to go to Europe. Mainly because their governments have authority over the people of the state.
You would use the Equal Area Projection because it more accurately shows the size of landmasses. In the Mercator Projection While border shape is well preserved in an elegant flat map the stretching of the image done in order to preserve this distorts the map by making it appear as if Greenland is almost the same size as south america even though in reality Greenland is much smaller.
The problem with the Great Depression of 1929 and the subsequent years
was that actually government did nothing to intervene. President Herbert
Hoover believed that government should interfere and that the market
will balance itself out. That is one of the reasons that President
Roosevelt won with a landslide with his promise of the New Deal.
In
2008 the government took a much active role in combating the Great
Recession. For example, the government even bailed out some banks that
were in trouble as well as provided emergency help. They also proposed
and passed many laws that would help prevent this kind of situation in
the future.
My best guess would be "C"
