What happens to a bill that has been passed by Congress but vetoed by the president? It is sent to the Supreme Court, which decides whether or not it is constitutional. It dies unless Congress overrides the veto by a two-thirds majority in each house. It passes without the support of the president. It is delayed for one full year, after which Congress must vote on it again.

The correct answer is: It dies unless Congress overrides the veto by a two-thirds majority in each house.

Explanation:

When the president vetoes a bill Congress has to analyze his arguments. If Congress doesn't agree to them it can override the president's veto by a two-thirds majority both in the House of Representatives and the Senate.

The first option is wrong because the Court analyzes a bill only when it's called to do it.

The third option is wrong because if it was like this the veto would be useless; the veto forces the Congress to analyze the president's arguments against the bill.

The fourth option is wrong because there is no obligatory time before the bill is voted.
