De las luchas internas de México durante la que cierra reforma se dieron por qué qué

The initial goal of the Mexican Revolution was simply the overthrow of the Díaz dictatorship, but that relatively simple political movement broadened into a major economic and social upheaval that presaged the fundamental character of Mexico’s 20th-century experience. During the long struggle, the Mexican people developed a sense of identity and purpose, perhaps unmatched by any other Latin American republic. Many reforms had been established by 1940, when the goals of the revolution were institutionalized as guidelines for future Mexican policies. The violence of 1910 gave a clear start to the Mexican Revolution, but scholars disagree on an end point: as a convention many use the year 1920, but some end it with the 1917 constitution or events in the 1920s, and still others argue that the revolution slowly unravelled until 1940.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
