Answer:
c. Corey rehearsed his speech in the auditorium while his teacher looked on.
d. Eric makes sure that he finishes his speech early so he has time to spare for questions.
a. Susie delivered her speech confidently and accurately.
Explanation:
In the first case, it is clear that Corey simulated the presentation because he tried to approximate to the conditions that he was going to experience in the actual presentation. He did so by rehearsing in an auditorium while his teacher looked on. In the second case, Eric finished the speech early so he would have time for questions. This shows effective timing because he accurately considered the time he was going to require. Finally, in the third case, Susie is likely to have rehearsed often because of how confidently and accurately she presented her speech.
