'No taxation without representation." That's a motto my teacher taught me, well she got it from the colonist, this is what they said to the king In response to all the taxes. A grievance is something that is really unfair, and is placed with no purpose. Britain kept on taxing the colonist with no reason, you wouldn't believe the taxes they would give.
Hope I helped. :)
James Madison was the person behind the federalist papers. He later became the president of the U.S.
I never reviewed this in class but I do remember that my teacher said that Rome had a strong army. I know its not B, C, and I don't think its D.
Hopefully this helped you.
