Explanation:

A proponent of the Georgia law would most likely have argued that it would make blacks and whites “separate but equal.”

Plessy v. Ferguson was a high profile case in the Supreme Court in 1896 after it was ruled that the separate but equal doctrine was Constitutional. This happened after a black man Homer Plessy refused to sit in a car that was "made for blacks".

the three-fifths compromise was proposed by james wilson and roger sherman, who were both delegates for the constitutional convention of 1787. however, the three-fifth compromise has its roots further back in history, dating back to the continental congress in 1783. the compromise was a result of the apportionment of taxes being related to land values.
