Slaves in NEW ENGLAND: There was very few slaves in New England, although, the ones that were there were typically butlers, sailors, launderers, and grooms. Very few were even artisans, such as carpenters and blacksmiths.
Slaves in MIDDLE: Once again, there was not a ton of slaves in the Middle region. They did jobs similar to the ones in New England (not much farming), but most of them did housework such as bringing firewood, water, and food.
Slaves in SOUTH: The majority of slaves were in the South region. Nearly all slaves here did plantation work, like farming. Cash crops were grown such as tobacco, rice, and cotton. Very very few were household slaves, or working similar jobs to the Middle Region & New England.

I suspect that's the phrase you're looking for, even if you haven't provided us with a list of phrase choices.

And many "Jim Crow" laws, as they were called, compelled blacks to stay separated from whites in society.
Its not 1 because Pilgrams were Christians while Puritans were Catholic.
Its not 2. Because of prior research.
Its not 3, because of logic.
Its not 4 because of the distance of where they lived.
So my logical guess is NUMBER 5.
