The US believed in isolation, if another country attacked the US that is the only way that we would get involved, therefore we tried to stay out of the mass killings and havoc that the Germans and Japanese were creating until we felt that it involved the US. The US did not want to pick a side and have to stay loyal to that side and go to war when that country did because of the alliance. The US finally joined in to help the allied powers to supply them with weapons/military troops. They did not enter the war until December 1941.
Abolitionists employed each of these techniques. The underground railroad was a system used to help slaves escape.

A presidential government is based on the relationship between the legislative power and the executive.
The presidential system or presidential system is a form of government in which, once a Republic is constituted, the Constitution establishes a division of powers between the executive power, the legislative power, the judiciary, and the head of state, in addition to holding representation formally of the country, is also an active part of the executive power, as Head of Government, thus exercising a dual function, because he has the powers of the Government, being elected directly by the voters and not by Congress or Parliament.
The president is the body that holds the executive power, while the legislative power usually concentrates the congress, without prejudice to the powers that the president has in legislative matters.
Life before medicine was probably honestly horrible, there was nothing to cure diseases, sickness and probably led to more deaths when people got sick because they had nothing to fight it off with, now that we have medicine we have been given chances to beat the sickness and to become healthier.
No one event was the actual cause of the revolution. It was, instead, a series of events that led to the war. Essentially, it all began as a disagreement over the way Great Britain treated the colonies versus the way the colonies felt they should be treated.
Americans felt they deserved all the rights of Englishmen. The British, on the other hand, felt that the colonies were created to be used in the way that best suited the crown and parliament. This conflict is embodied in one of the rallying cries of the American Revolution: No Taxation Without Representation.
