Answer:
a. banks
Explanation:
The slaves in the South were put to work in places where the majority of the population either didn't wanted to work, or where there was a lack of labor force. Whichever the way, the slaves were only allowed to work manual labor, usually the hardest one, so they were mostly included in the agriculture, and some in the iron works, or laundries. The banks were definitely not a place where they were allowed to work, and even if they were, they would have not been able to because they were not educated for such a work.

Because the unilateral system is easier to get as close to the dimension the engineer specified.
Bilateral tolerancing (also known as symmetric tolerancing) is a method of tolerancing a dimension using equal plus and minus deviations from the nominal dimension.
Unilateral tolerances (also known as asymmetric tolerances) on the other hand specify a deviation in only one direction, either plus or minus, from the specified nominal dimension. Unilateral tolerances may also take the form of plus and plus-plus, minus and minus-minus, or plus or minus some amount and plus or minus a lesser amount.
