Answer:
A.
1. Apolinario Mabini was one of the foremost of the Philippine revolutionary heroes. He was the "brains" of the revolution. Crippled as a young man by polio, he realized that his physical limitations not only limited his personal life but the struggle his beloved homeland was undergoing to become a sovereign republic.
2. He was captured by U.S. troops in December 1899 and, because he refused to swear allegiance to the United States, was exiled to Guam, not being allowed to return home until a few months before his death. Mabini wrote La revolución filipina, which was published in 1931.
3.Because of his role as advisor during the formation of the revolutionary government, and his contributions as statesman thereafter, Mabini is often referred to as the "Brains of the Revolution," a historical moniker he sometimes shares with Emilio Jacinto, who served in a similar capacity for the earlier revolutionary.
