Final answer:
John Adams played many roles in the Second Continental Congress, but he did not write the rough draft of the Constitution.
Step-by-step explanation:
John Adams played many roles in the Second Continental Congress, but he did not write the rough draft of the Constitution. One of his roles was to nominate George Washington to lead the Continental Army, which he did on June 15. Adams also asked Thomas Jefferson to draft the Declaration of Independence, and he played a role in coaxing the colonies to declare independence. However, the writing of the rough draft of the Constitution was not one of his roles.
