In which of the following scenarios are delivery and noise most likely the primary concerns of the speaker? a. sheree has been asked to speak about social security to a mixed group of college students, business people, and senior citizens. b. erin is giving a motivational speech to a very large group of high school students seated on bleachers in the school’s gymnasium. c. charles has been invited to mrs. delaney’s classroom to speak to her elementary school children about fire safety. d. ethan is giving a highly technical presentation on biomedical engineering involving several working models, computerized graphs, and video clips to a group of doctors, scientists, and engineers.

The correct answer is option B. In the scenario of Erin giving a motivational speech to a very large group of high school students seated on bleachers in the school's gymnasium, delivery and noise are most likely the primary concerns of the speaker. Delivery is the way and quality of the presentation of the speech when public speaking. Giving a motivational speech to an audience of mostly teenagers can be challenging. Because teenagers are going through a stage in which they develop their own moral values, they usually question everything that comes from an adult, because they might feel as if it is being imposed on them. Therefore they might not receive in a positive way the motivational speech. Noise is going to be a concern for the speaker in this scenario because the speech is going to happen in a gymnasium full of chatty students, that probably do not want to participate of such activity.
