Hi!
Muslims believe that the last Prophet was Mohammed. (Also spelled Muhammad). =)
Although Locke and Rousseau wrote prominent treatises on the social contract, Thomas Hobbes introduced the idea of it. He argued that human beings were evil in nature, and thus needed to enter a contract in which everyone basically agreed not to kill each other (i.e. in his natural state, although completely free, man would always be wary of subjected to another man's brutishness. Whereas in society we are all supposedly better off-even if there are sacrifices involved-because there is an agreement binding each man into behavior that's meant to contain man's evil nature).
The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The President presents an award to the artist who created a statue in
honor of the 500th anniversary of Christopher Columbus' voyage to
America. The president's role is the Chief Executive.
As the leader of the executive branch, the President of the United States has many roles.
He is the Chief of the State. He is the commander-in-chief of the US armed forces(Army, Navy, Air Force, and Coastal Guard). He is the Chief of State. He has the power to appoint the members of his cabinet. And he is the Chief Diplomat.
I believe the correct answer is the third one.
