Evaluative Comments

1.       Choose one of the two speeches. Why do you think that this speech is an effective example of an informative speech?
a.       I think the speech about medical robots is an effective example of an informative speech because it provides the audience with information they might not have known before. The speaker provides a preview to the audience, and sticks with it throughout the speech.  The author also explains the information in human terms that are easy for the audience to grasp. It does e really good using transition from main points to another which makes the point to easy to understand and remember.
     How are these speeches "audience centered"?
             Both speeches are audience centered because both authors throughout the speech involve the audience.  For example, in the introduction of the hot chili pepper speech the author appealed to the senses of each member of audience. Both authors tell the audience to imagine something while using descriptive imagery to help the audience see/feel something in order to fully understand the point(s) the author made.
