Which of the following actions could be performed only by federal government and not by a state government?
A. The legislature passes a new income tax. B. The chief executive makes a treaty with another country. C. The chief executive appoints a judge to fill a vacant seat. D. The legislature passes a law approving funds for roads and highways.
It would be B because state governments (Arizona,Texas,New York etc.) deal with there state while the federal deals with the country (United States) as a whole and making a treaty with another country would deal with the federal government.
