The correct answer is veto a bill passed by Congress.
In the American government, there are three branches to the federal government. These include the legislative, executive, and judicial branches. Each of these branches has the ability to check the action/power of the other branches.
In this case, the executive branch (aka president) has the ability to stop a bill passed by Congress from becoming a law by using the power of the veto.
Referendum reform allowed the votes to approve or reject laws passed by the legislature.
