All of the followings are acceptable courses of action for a president faced with a bill congress passed and is requesting he sign except

1. Vetoing the bill

2. Signing the bill into law
3. Ignoring the bill and taking no action
4. Sending the bill back to Congress with suggested changes

The correct answer is 3. Ignoring the bill and taking no action. As the president, one of the acceptable courses of action would not be to ignore the bill and take no action. The president is expected to either sign the bill, veto it, or send it back to Congress with suggested changes. Ignoring the bill would result in it becoming law without the president's signature, which is a passive way of handling the situation.
