The correct responses regarding the actions taken by the First Continental Congress that contributed to the American Revolution are:
- They created a resolution with grievances against the king, which led to further conflict.
- They voted to boycott all trade with Britain until Parliament stopped taxing the colonies.
The First Continental Congress did not make a formal declaration of war on Britain, nor did they send a militia to Concord; those actions are associated with events that occurred later, such as the battles of Lexington and Concord.
