Due to growing financial problems in the newly formed Soviet Union, Vladimir Lenin decided to: a. Permit some capitalism and private-ownership
b. Eliminate the need for shopkeepers
c. Limit the amount of grain one could harvest
d. imprison royalists who disagreed with the Bolsheviks

The answer for this is A.

The answer here is Italy. Italy was a country that first fought for the Entente forces (which included Germany) in the First World War. During the course of WW1, the Italians switched sides and started fighting for the Triple Alliance (Britain, Russia, and France). This meant that the forces of the Triple Alliance eventually had another source of soldiers which were fighting for their cause.
