I saw one sentence in GMAT.
Downzoning ,zoning that typically results in the reduction of housing density ,allows for more open space in areas where there are few services and little available water.



I wanna ask that "downzoning,zoning" have the same meaning?



THANKS A LOT!!!!

No, as the sentence itself explains. Downzoning is one form of zoning.

We insert a space after a punctuation marl, not before it.
