How was President Roosevelt’s proposal?

Which proposal?
It doesn't tell me "which proposal"
It just says this on top the question
“The need for collecting large campaign funds would vanish [go away] if Congress provided an appropriation [federal money] for the proper . . . expenses of each of the great national parties, an appropriation ample [large] enough to meet the necessity [the needs of the political parties]. . . . Then [the parties should agree that] no party receiving campaign funds from the [federal] Treasury should accept more than a fixed amount from any individual . . . and  [detailed information about the money taken in and spent] could without difficulty be provided.”
—President Theodore Roosevelt, Annual Message to Congress, December 3, 1907
That IS the proposal! How was it WHAT? Your question is incomplete.
