To project your voice:
a. shout so you can be heard over noise and distractions.
b. avoid drinking water before or during your presentation.
c. raise the pitch of your voice.
d. slow down and use shorter phrases.

The correct answer is D. Slow down and use shorter phrases.

Explanation:

Projecting the voice means that your voice can be heard clearly, that it is easy to understand the words you are saying, that the natural sound of your voice is not altered in any way, both at low and high volume, all this maintaining a healthy vocal production, free of tensions.

You may be surprised to have read that the voice can be projected at a low volume, since there are many people who "project the voice" means "to hear more."

the correct answer option is b. a single paragraph.

explanation:

when you are thinking about paragraph​ topics, you should always choose a subject that can be adequately addressed in a single paragraph.

a paragraph is a piece of writing consisting of a few sentences that deal with a single theme. it has only a single idea that the paragraph revolves around and talks about.

so a paragraph topic must be chosen wisely where a single idea can be communicated in a single paragraph.
