Voting is important so we can get to know that who can lead better or who is better for the society; it shows who the majority likes.
Before steam engines most factories were powered by wind or water or horse!!
I agree with the person above - the way that the plebeians gained the right to vote and hold political office in the Roman Republic is by threatening to leave Rome and build a new city.
Since that was not an option, they were allowed some rights.
To quote Amendment 25, Section 2 of the United States Constitution, "Whenever there is a vacancy in the office of the Vice President, the President shall nominate a Vice President who shall take office upon confirmation by a majority vote of both Houses of Congress."
Therefore, A is wrong because it has to be Congress, not the Supreme Court. B is wrong because it doesn't have to be 2/3, it just has to be greater than 1/2. And D is wrong because it says nothing about the President presenting the Vice President. Therefore, C is the correct answer, because Congress is the one doing the approving, and it's done with a majority vote.
