Which of the following guidelines would not be when evaluating a speech?

did the speaker introduce the topic clearly?
did the speaker use verbal strategies, nonverbal strategies, and rhetorical language to reinforce the information?
did the speaker pick the topic, or was the topic assigned?
did the speaker support each main idea with appropriate details?

The guideline that would not be helpful when evaluating a speech is "Did the speaker pick the topic, or was the topic assigned?"

Explanation:

The aspects that are analyzed when we evaluate a speech make reference to the way the speech was presented, this includes every literary, grammatical and communicational aspect of it, then the question "Did the speaker pick the topic, or was the topic assigned?" does not make reference to the performance but to the origin of the selection of the topic and it is not an analysis area.

because he is using a description to provide evidence to support his argument.
