Questions: The role of the Senate in regard to treaties is to approve international treaties, advise during negotiations, have the president of the Senate sign the treaty, negotiate the terms and conditions of the treaty.

The answer is to approve international treaties.

This is correct. According to the U.S. Constitution, the Senate has the power to approve international treaties. Specifically, a two-thirds majority of the Senate must consent to a treaty for it to be ratified.

While the Senate may provide advice and consent, it does not directly participate in the negotiation process. The President and the executive branch are primarily responsible for negotiating treaties.

This is incorrect. The President of the United States, not the president of the Senate, signs treaties.

This is incorrect. The negotiation of treaties is the responsibility of the President and the executive branch, not the Senate. The Senate's role is to provide advice and consent after the treaty has been negotiated.
