3) Representation in Congress
4) Border disputes with Great Britain
Answer:
3) Representation in Congress
Step-by-step explanation:
As you can see, the above excerpt directly cites the concern of northerners in allowing the Three-fifths Compromise to be maintained for southern states. This is because the Three-fifths Compromise allowed three out of five slaves to be counted as an individual to determine the number of representations each state would have at the congress. This gave the southern states power, as it increased their population and allowed them to have a large government representation preventing the northern objectives from being implemented.
