The correct answers regarding the Three-Fifths Compromise are:
B. would allow slave states more representatives in congress.
D. allowed southern states to count their slaves as part of their population.
To clarify:
- A is incorrect because the compromise was indeed agreed upon during the Constitutional Convention and had support from both northern and southern states.
- C is incorrect as the Three-Fifths Compromise did not require slaves to work between three and five years; rather, it was a formula for counting slaves for purposes of representation and taxation.
