A) Public support for the veterans’ rough treatment helped turn the country decisively equally in support of President Herbert Hoover in that fall’s election.
B) Public revulsion at the veterans’ rough treatment helped force President Herbert Hoover to replace his Vice President in that fall’s election.
C) Public revulsion at the veterans’ rough treatment helped turn the country decisively against President Herbert Hoover in that fall’s election.
D) Public support at the veterans’ rough treatment helped turn the country decisively equally in support of Hoover’s sending of American forces to protect American interests during the Japanese occupation of Shanghai, and hence his campaign in that fall’s election.
