In John's speech on immigration reform, what technique is used when he reviews and reemphasizes earlier points?

In John's speech on immigration reform, the technique of reviewing and reemphasizing earlier points is known as an internal summary. This technique serves to reinforce key messages and ensure that the audience retains important information. It acts as a cognitive reminder for the listeners, helping them to connect the dots and understand how the various aspects of the argument relate to one another.

By using internal summaries, John can enhance the clarity of his speech, making it easier for the audience to follow along and grasp the significance of the points he's discussing. This method is particularly effective in persuasive speeches, as it strengthens the audience's memory of the information presented and aids in persuasive impact.

The other options reflect different functions; for example, verbal transitions help guide the audience from one point to another, conclusions wrap up the speech, and chronological summation outlines events in a time-based manner. However, the particular focus on reemphasizing earlier points aligns specifically with the concept of an internal summary.
