Knowledge secured in this manner may be used with signal effect in a speech, either to supply all the material or to cover certain portions. If you listen to many speeches (and you should), notice how often a speaker introduces the result of his interviews—formal or merely conversational—with persons whose statement he is certain will impress his audience.
EXERCISES
1. Make a list of five topics of which you know so little that you would have to secure information by interviews.
2. Of these choose two, define your opinion or feeling in each, and tell to whom you could apply for material.
3. Choose one dealing with some topic of current interest in your locality; define your own opinion or feeling, and tell to whom you could apply for material.
4. Explain exactly why you name this person.
5. Prepare a set of questions to bring out material to support your position.
6. Prepare some questions to draw out material to dispose of other views.
7. Interview some person upon one of the foregoing topics or a different one, and in a speech present this material before the class.
