Final answer:
The Electoral College Compromise was concerned with how to elect the president, and it was a compromise that balanced the power between large and small states and addressed the issue of slavery.
Step-by-step explanation:
The Electoral College Compromise was concerned with reconciling the difference over the issue of how to elect the president. The delegates to the Constitutional Convention wanted to establish a system that would balance the power between the large and small states and also address the issue of slavery. They agreed on a compromise that created a special body of electors who would be selected by the states based on the number of senators and representatives each state had. This compromise prevented the direct election of the president and allowed for a fair representation of states.
