Which of the following would have been favored by such "New South" advocates as Henry Grady?

enforcing, by law, increased agricultural development

eliminating tariffs on imported goods

electing more black people to public office

increasing industrialization by using local resources

The correct answer is D. increasing industrialization by using local resources. To be more precise New South was a slogan that the new reformers used to call for a modernization of society and attitudes and reject the economy and traditions of the Old South which meant slavery based plantation system. Grady was the first to use the term so he is considered to be the initiator of the idea. Since the industrialization was very developed in the North, the South also wanted to promote it, but based on the local produce.
