Answer:
3. The office of the president might become too powerful.
Step-by-step explanation:
The framers of the Constitution intended Congress to be the most powerful branch, not the executive. They feared that the executive might become too powerful by the excessive use of executive powers or orders.
This fear has become a reality because presidents have become more and more powerful each decade. For example, Congress has not formally declared war since 1941, but all presidents ever since have made use of their executive power to launch military interventions around the world (Korea, Vietnam, Grenada, Panama, Afghanistan, Iraq, Libya, Syria).
