Answer:
The correct answer is <u>B</u>: use eye contact and speak clearly and deliberately.
Explanation:
If we want to give an effective presentation, we should use eye contact and speak clearly and deliberately in order to expose our speech the best we can.
We shouldn't focus on the audience’s opinions on our topic, as we choose the topic and made a presentation regardless of their interests and opinion. Therefore, option E also cannot be considered as a correct answer, because we should not base our presentation on analyzing the audience, but develop the content and quality of our presentation.
We also shouldn't reference only our own thoughts and opinions about the topic, because, in that case, our presentation would not be considered as relevant and it would lose its credibility.
Option D also couldn't be a correct answer, as the usage of the technical terms when speaking to an informal audience would be inappropriate and presentation would not be exposed effectively, as the audience would not understand what we want to say.
