How did zoning laws help to reduce the danger of pollution?
A: they required factories to limit the use of chemicals
B: they kept factories outside of residential neighborhoods
C: they relocated factories to rural areas from far away cities
D: they established building codes to reform factory plumbing
Isn't it A? I'm not sure
Im not really sure on this one. However, I do think the answer is B. Since, moving the factory's away from neighborhoods would mean moving the source of pollution farther away.
