Answer: C. Did the speaker present a clear opinion on the topic?
In an informative speech, all of these characteristics are important except for the inclusion of an opinion. This is because the author of an informative essay does not need to have an opinion on the topic he is writing about. An informative speech needs effective transitions, in order to ensure that the text flows well and that all new ideas are linked to the previous ones. Moreover, an informative speech must state the topic, or main idea of the speech in its introduction. Finally, the speech requires a specific and clear purpose.
