Question

I need your help on number 1 please

Answer 1

Dude no person can help you. This is an opinion question. If you use what people say it is plagiarizing. 

Answer 2

"We the people" is a short 3 word part of the constitution. It may not look like much but by saying "we the people," the writers of the constitution speak for all of the United States of America. (this is agreeing that it is the most important)
