Answer :
C. It lessened the power of foreign investors and distributed land more equally.
Explanation:
Some of the main problems that caused the Mexican Revolution were how different the rich and the poor were. Many of the land that poor citizens did have, which was already not a lot, was taken by the rich due to terrible and unfair ruling. Diaz, who was the ruler at this time, was not good to the citizens and greatly favored the rich and didn't help the poor at all.
After the Mexican Revolution, the problems still needed to be addressed and fixed. This was when the Constitution of 1917 was finally used and it started to resolve some of the problems that first started the Mexican Revolution. This constitution made it so there was a limit on how much land someone could own and it also distributed land equally among the citizens so nobody was left out. Along with this, it lessened the power of foreign investors and made it so they were not as powerful and controlling as before.
