What was a main aim of the first continental congress?
1) seek to repeal the stamp act
2) protest the enforcement of the navigation acts
3) to have the intolerable acts revoked

I believe the answer is: 3) To have the Intolerable Acts revoked

The intolerable act was created to punish the colonists for their resistance in following new tax regulations created by the British government. The first continental congress was enacted to ensure that the government in united states help the British empire to instate the punishment.

the constitution gives congress the power to regulate commerce "among" the several states.
