Answer:
B. "One proposal "included clear boundaries" for where slavery could and couldn't exist".
D. "One proposal "included a clause to compensate slave owners" if fugitives could not be returned".
Step-by-step explanation:
The latitudes and degrees separated the line for territories of the abolitionists. Every state was a subject of the regime federation as the new status was admitted without slavery. This was, however, decided by the specific constitution.
However, congress was supposed to pay the slave owners in accordance with the law. The "total number of slave" nevertheless did not match due to Nordic oppositions that arose. Despite the widespread support of Crittenden, the congress did not enact his proposal; however, the incoming secretary reviewed the proposal and backed his plan.
