Which action on the part of the progressives had the LEAST immediate effect on South Carolina

1. ending child labor
2. ending business trusts
3. outlawing the use of alcohol
4. extending suffrage to women

Outlawing the use of alcohol had the least immediate effect on South Carolina, as the state had already implemented Prohibition laws prior to the progressive era. Ending child labor, ending business trusts, and extending suffrage to women would have all had more immediate and significant impacts on the state during the progressive era.
