7. What two answers are reasons that Congress decided the election of 1800?

a.)Based on the outcome, it was mandated by the U.S. Constitution.*
b.)The popular vote was a tie.
c.)No candidate won the electoral vote.*

The two correct answers are:

a.) Based on the outcome, it was mandated by the U.S. Constitution.
c.) No candidate won the electoral vote.

To get to these answers, let's break down the election of 1800 and the decision made by Congress.

In the election of 1800, there were two main political parties: the Federalists, led by John Adams, and the Democratic-Republicans, led by Thomas Jefferson. When the Electoral College votes were counted, Thomas Jefferson and his running mate, Aaron Burr, ended up with an equal number of electoral votes.

Now, according to the U.S. Constitution, at that time, each member of the Electoral College had two votes but didn't distinguish between President and Vice President. The candidate with the most votes would become President, and the candidate with the second most votes would become Vice President. However, since Jefferson and Burr received an equal number of electoral votes, it created a tie for the presidency.

Because of this tie, the decision of who would become President was then passed on to Congress. This is where answer a.) comes into play. According to the U.S. Constitution, when a tie occurs in the Electoral College vote, it is mandated by the Constitution that Congress decides the election. So based on the outcome and the Constitution, it was Congress's responsibility to break the tie and decide who would become President.

Furthermore, answer c.) is also correct. As mentioned before, neither Jefferson nor Burr won the electoral vote outright. They had the same number of electoral votes, creating a situation where no candidate won the electoral vote. This fact played a significant role in Congress's decision-making process as they had to resolve the deadlock and select the next President.

So, in conclusion, Congress decided the election of 1800 because it was mandated by the U.S. Constitution when no candidate won the electoral vote.
