The answer is not provided in the passage. The three types of government powers are exercised by different parts of the national government. Concurrent powers are exercised by both the federal and state governments, enumerated powers are listed in the Constitution and belong to the federal government, and implied powers are not explicitly listed in the Constitution but are necessary for the federal government to carry out its enumerated powers. Therefore, it is possible for different parts of the national government to exercise all three types of powers.
