Answer:
The use of counterclaims
Step-by-step explanation:
According to a different source, these are the two excerpts that this question refers to:
Read the excerpt from Martin Luther King Jr.'s "The American Dream" speech.
In a real sense, we must all learn to live together as brothers, or we will all perish together as fools.
Now read the excerpt from the Governor George Wallace statement.
The true brotherhood of America, of respecting the separateness of others . . and uniting in effort . . has been so twisted and distorted from its original concept . . .
What technique makes the two excerpts effective when used together?
The technique that makes these two excerpts effective is the use of counterclaims. In these passages, the speakers suggest main ideas. However, these are strengthened by the fact that they are supported by counterclaims. In the first example, King argues that we must all live together as brothers. This is his main claim. On the other hand, in the case of Governor George Wallace, he claims that the true brotherhood of America lies in respecting the separateness of others. This statement serves as the counterclaim to King's argument. Therefore, these statements become more effective when used together.
