The answer is: B. The Three-Fifths Compromise vs. the Great Compromise
The great compromise of 1787 was major agreement that settled the dispute of proportional representation of states in both the upper and lower houses.
The three-fifths compromise was also a major dispute, concerning how will slaves count towards a state's population in order to determine the number of house of representatives seats and taxes.
Both of these disputes proved to be major factors during the Constitutional Convention.
The Connecticut Compromise (also known as the Great Compromise of 1787 or Sherman Compromise) was an agreement that large and small states reached during the Constitutional Convention of 1787 that in part defined the legislative structure and representation that each state would have under the United States Constitution. It retained the bicameral legislature as proposed by Roger Sherman, along with proportional representation of the states in the lower house, but required the upper house to be weighted equally among the states. Each state would have two representatives in the upper house.
I cannot see any answers you have but I can give you a brief summary. After ww1 Germany was embarrassed, out of money, and mad as they lost the war they lost leaders to so they had nobody to lead them and Hitler saw his opportunity to take control of Germany when they most needed a strong leader.
