Question

Porfirio diaz supported which fellow revolutionary before they turned on one another

Answer 1

The correct answer is Venustiano Carranza 

Although they used to work together in ensuring democracy, they turned on each other because Venustiano believed that Porfirio Diaz was becoming too conservative and even totalitarian so they started opposing each other. Venustiano's anger grew even more when he lost the elections due to the lack of Diaz's support.
