Question 18 SA-3. Here is the text (p. 170/2):

Huerta was finally defeated in 1914, and Carranza became president at the head of the coalition of Constitutionalists. For the first time since Independence radical mestizos, at the head of large numbers of Indigenous, had wrested power away from the creole elite. Carranza was able to consolidate his power by accepting some of the more radical proposals made by Zapata and others. These were institutionalized in the revolutionary constitution of 1917, which included such far-reaching provisions as land reform, social security protection for workers, restrictions on the power and wealth of the Church, and nationalization of oil and mineral riches.
