Which best explains why the stamp act of 1765 was significant?
1.the law was the first direct tax imposed on the american colonists.
2.the law applied equally to colonial men and women.
3.the law was the last tax parliament imposed before the american revolution.
4. the law was the last tax parliament imposed before ending all colonial taxes.

The correct answer is 1.The law was the first direct tax imposed on the American colonists. 

Before it, people had what they called salutary neglect, which meant that the colonies didn't really have to obey all laws and do everything that the British parliament said, as long as they didn't create any problems. However, the stamp act changed that and Britain started pressuring them to pay taxes and similar things.
