Question

how did the pri respond to a 1968 protest at tlatelolco over economic inequality?
the country appealed to the united states for help.
the government announced a series of new reforms.
the military fired into the crowd, killing dozens.
the party announced higher wages for laborers.

Explanation:

The Tlatelolco massacre in 1968 involved the Mexican government (with PRI in power) using the military to respond to the protest. The military fired into the crowd, resulting in the deaths of dozens. The other options do not align with the historical event: appealing to the US was not the response, no new reforms or higher wages for laborers were announced in response to this protest in this manner.

Answer:

C. The military fired into the crowd, killing dozens.
