How did common sense influence the declaration of independence?
by using most of the language and format of the declaration
by persuading the continental congress to meet and discuss independence
by introducing many of the ideas the declaration later expressed
by suggesting authors who could write the declaration

C (Introducing the ideas)

Before this independence thing started, the colonists never really thought of independence. After Common Sense was distributed, the colonists started thinking about what it would be like to be independent from Britain.

You can eliminate D easily, since Common Sense never suggests authors in any sense.

You can eliminate A, since it makes no sense. Common Sense was a pamphlet. It can't use the format of the Declaration of Independence.

You can eliminate B, since the Continental Congress was formed solely to discuss independence. It didn't exist for a different reason.

Thus, the answer is C. Hope this helps!

The answer is C: By introducing many of the ideas the Declaration later expressed.
