Answer:
Just like president Madero (murdered in a coup d'etat in 1913), the main issues that he faced when attempting to carry out reforms such as the agrarian reform was, on the one hand, the lower classes' impatience for the reforms to take place right away, on the other hand, he met the opposition of wealthy landowners (hacendados; latifundistas), un willing to give back the land they had snatched from small farmers in times of president Porfirio Diaz's administration (1876 - 1911).
In order to enforce his reforms, Carranza first presented a document, "Reforms to the Constitution of 1857," and as these reforms were rejected by many because of their limited scope. Instead, a new constitution was issued in 1917 which features a number of articles devoted the the right of people to free and public education, a working day of 8 hours tops, etc, This new Constitution, issued on February 1917, greatly expanded qualitatively and quantitatively the lukewarm reforms carried out by Carranza
