The two ways in which President Franklin D. Roosevelt played a role in the Bonus Army marches are "He offered them the opportunity to enlist in the Civilian Conservation Corps, and He provided food and shelter to the veterans during their marches."
During the second Bonus Army march in 1832, President Franklin Roosevelt allowed the veterans to be integrated into civil service through the Civilian Conservation Corps.
He also gave them food and ensured the band played for them during the march.
Option B is wrong because Roosevelt did not sign a bill authorizing early payment to veterans, he did the opposite, which Congress later vetoed in 1836.
Option D is wrong because Roosevelt did not decrease the benefits that veterans were receiving.
Option E is wrong because Roosevelt did not order the army to remove the veterans from Washington violently; rather, he welcomed them with food and band.
Hence, in this case, it is concluded that the correct answer is options A and C.
