number one im not too sure on but i have been pretty good and history all my life so im pretty sure that that one is true
number two if false the signing of the declaration was july 4 1776 but when it was approved was August 2 1776
and for number three i would also say false because back then every one had a choice of happiness life and liberty that was why it was made in the first place to create order and make life great.
