Answer:
B
Explanation:
Using a Z pattern is an example of a tactic that can be very effective in keeping the audience involved in the speech. Focusing too much on any one person can make that uncomfortable and also distract the speaker.
Scanning the room in a Z type pattern gives every member of the audience the illusion of being looked at and addressed individually by the speaker. This is useful tactic because people who feel involved will pay more attention to the subject matter.
Answer:
My grandfather spoke so quietly that his words were almost inaudible.
Explanation:
We are supposed to use the infixes (formative elements of a word) to form a word that will complete the sentence properly. According to the sentence, the speaker's grandfather spoke quietly. We can safely assume it was difficult for the speaker to hear the words his grandfather said. In that case, we need "aud", which is connected to the verb "hear". Since it was not possible to hear, we also need "in-", meaning "not", and "-ible", meaning "can be done". Together, they form the adjective "inaudible", which means "unable to be heard".
When we complete the sentence, it becomes:
My grandfather spoke so quietly that his words were almost inaudible.
