Question

One feature setting the southern colonies apart from the middle colonies was that

the soil was difficult to farm.
plantations had many enslaved workers.
harbors helped cities grow.
the population was diverse.

Answer 1

The Middle Colonies, particularly Delaware, were tolerant. They had diverse populations. Slavery was not practiced there, so this might be a deciding factor to your answer. Harbors alway get larger.

I think I'd pick the second one down <<<<<<=====

Answer 2

plantations had many enslaved workers.

Step-by-step explanation:

The southern colonies had fertile soil and needed lots of cheap labor, this created a perfect environment for people to buy slaves because they were good workers and compared to hiring people to work they were very cheap, so the southern states were filled with slaves in order to keep their economy going, this was the main difference between the middle and southern colonies, the amount of slaves that were brought to the colonies.
