The principle of Checks and Balances looks to enable each government branch (executive, judicial, and legislative) to apply a certain extent of influence over the other branches.
It was fundamental that the framers added it to the Constitution, as these functions guarantee the separation of powers. This is a key element for any Federal government to keep balance and ensure no individual branch gets too powerful in comparison to the others.
For example, the Executive branch can veto bills from the Legislative branch, but the Legislative branch can override that veto.
Hope this helps out!
The Marshall Plan (officially the European Recovery Program, ERP) was an American initiative to aid Western Europe, in which the United States gave over $12 billion (nearly $100 billion in 2016 US dollars) in economic assistance to help rebuild Western European economies after the end of World War II.
DURING WORLD WAR I:
War tends to disrupt traditional norms surrounding gender and sexuality, and the First World War between 1914-1918 was no exception. Keep in mind, the U.S. did not become involved in the war until 1917.
During World War I, many women entered the workforce for the first time. With significant numbers of men away in Europe, women were needed in various capacities. It is believed over 20,000 women worked as nurses during the war. Others worked in clerical positions for the U.S. Government. Telephone and radio operators were also common positions for women.
On the home front, women assumed greater responsibility in public life as significant portions of the male population were 'over there' (as Europe was referred to during that time). Women too young or unable to work helped the war effort in various ways, such as planting 'victory' gardens.
