Answer:
Three major compromises (agreements) were made at the Constitutional Convention of 1787. The main issues settled were the election of a president and the form of representation they would adopt.
Explanation:
The Constitutional Convention was created to discuss and reach an agreement on the weaknesses of the national govenment. The three major compromises that were made included:
1) The Great Compromise (related to <em>representation in Congress)</em>: they agreed to have two chambers, the Senate (based on equal representation of states, no matter its population) and the House of Representatives (based on number of population).
2) Three-Fifths Compromise: once they agreed on the representation of each state, they had another issue which was the counting of slaves. The North opposed the South since the southern states would have a greater amount of representation (due to the number of slaves in the south). They agreed to count 3 individuals every 5 slaves (three-fifths).
3) The Election of the President: the delegates agreed on the need for electing a president, but they struggled to agree on <em>how</em> this president would be elected. They finally agreed on creating an Electoral College, which would be made up of <em>electors (voted by people)</em> who would vote for the president.
The issues that remained unsettled were: the decision of having a <em>strong central government</em> and the <em>replacement of the Articles by a new constitutional structure</em>.
