Read the excerpt from "Lessons of Dr. Martin Luther King, Jr."

The time is now for people, of all races and backgrounds, to sound the trumpets of change. As Dr. King proclaimed, "There comes a time when people get tired of being trampled over by the iron feet of oppression."

The strong language in this passage shows that Chavez wants people to

feel that true equality is a nearly impossible goal.
always follow in their leaders’ footsteps.
work together to fight against social injustices.
change their opinions about peaceful resistance.

C). Work together to fight against social injustices.

Explanation:

Language always play a vital role in creating the desired tone or mood in a writing that assists in conveying the message more effectively and eliciting the intended feelings or response from the audience.

In the given excerpt, the strong language implies that Chavez firmly wished that 'people must come together irrespective of the background or race they belong to as a force to battle against the social evils or injustices' and 'sound the trumpets of change.' The use of sturdy and impressive phrases like 'be trampled over by the iron feet of oppression' reveal his disagreement towards these injustices strongly. Thus, option C is the correct answer.
