The “necessary and proper" clause (sometimes called the "elastic clause") refers to
the (A) right of the Supreme Court to declare laws unconstitutional
(B) obligation of each state to give full faith and credit to the laws of the other states
(C) power given to Congress by the Constitution to make necessary laws which
carry into execution the other powers specifically granted to Congress.

- "the past is made of multitudinous items ranging from anything that can be collected, recollected or assessed to originate in the past. as such, the past is a gallimaufry of particulars that may not have been related in any way. however, the human mind seeks organization to understand concepts and other things. the human mind therefore seeks relationships in explaining and studying the past. history being a humanity, dictates that historians have to serve this human trait by bringing structure to details of the past. historians do this by creating interpretive frameworks that capture as many details as possible."
