Which parts of a presentation should be the most general
A. Introduction and conclusion
B. Introduction and outline
C. Outline and conclusion
D. Outline and body

A. Introduction and conclusion

Explanation:

It's certainly an introduction and the conclusion that should be the most general. The introduction should be 10% maximum of the total content, and the conclusion must not be more than 10-20% of the total content. Also, an introduction should generalize what you are going to include in your speech so that all can have an idea that what you are going to speak. The body of the speech can be not so general, and you can prove your better quality over there. But please make sure that you generalize all your findings through the conclusion through simple English. And you can ensure through your conclusion the chances for future research as well related to your topic. And that will ensure your speech is a good one.
