Answer 1

D.He speaks more loudly to emphasize the importance of a point he is making.

Answer 2

The correct answer is D.

Non-verbal communication refers to the transmission of information through the different senses.

By raising his voice, Kennedy is using paralanguage, which is a way to convey emotion through the differen use of  pitch, volume and intonation. This forces the audience to listen and to pay more attention, thus giving this part of his speech extra emphasis.
