The correct answers are as follows:
1. Expressed Power--- A power that is specifically granted in the Constitution.
Expressed powers refer to powers that are specifically granted to the federal government. The constitution explicitly states that the federal government has powers to mint or produce money, declare war, run the post office system, manage armed forces and carry out commercial activities.
2. Implied Power--- The "necessary and proper" clause is the basis of implied power.
Implied power refers to the power granted to the Congress that is not explicitly stated in the constitution, but is logically implied or assumed from the "necessary and proper" clause. Implied powers grant the Congress with powers to create laws which are necessary to execute and properly practice expressed (or explicitly stated) powers.
3. Concurrent power--- A power held by both the federal government and states
Concurrent power refers to powers that are shared by both federal and state governments simultaneously. Examples of powers shared by both federal and state governments include: the power to levy taxes, regulate elections, manage infrastructure and roads, establish legal and court systems, etc.
