The colonists had a problem with the Tea Act of 1773 because A. they saw it as the British government giving the East India Company a monopoly on the tea market in the colonies.
Therefore they organized the famous Boston Tea Party which prolonged the war.
In short, Germany was close to being defeated, and America wanted to be part of the post war carve up (when territory was divided). The US was supplying war materials to the Allies and could not do so while maintaining complete neutrality. There was also the sinking of the British ship Lusitania which angered the US. Also, the Zimmerman telegram.
D. You go any further north and its too cold :)
