Answer:
Here's a sample response.
A speech becomes boring when it is repetitive or if it is of a subject that does not pertain to the audience. In addition, if a speaker talks in the same monotone voice or has little movement or gestures, it causes the audience to loose interest. One's environment may cause boredom as well. For example, if the audience members are left in a bland environment or the speaker leaves little to focus on, the audience looses interest and becomes bored. In addition, if the speaker doesn't adapt the way they speak to fit with the audience, the audience will become confused. For example, if one is talking about inter-molecular organisms to a person who doesn’t know anything about them, the audience will become confused and loose interest.
