The correct answer is C) Experts conducted research to inform politicians about drafting bills.
The role that experts such as business leaders, labor leaders, and university professors played in the Wisconsin Idea reforms was as experts that conducted research to inform politicians about drafting bills.
The Wisconsin Idea considered the notion that the government should be controlled by the people who vote in order to have an efficient administration, not to be controlled by businessmen. It was conceived by Wisconsin Senator Bob La Follette. For that to happen, La Follette considered that the government required the assistance of economist, scientist, lawyers and school professors.
