Question

Which of the following topics is an example of an entertaining speech?

an introduction of a guest speaker at school
the benefits of regular exercise
the best thing about being a twin
why people should vote for a political candidate

Answer 1

An entertaining speech's purpose is for the audience to enjoy it.
An introduction is usually a small speech so you can get to know the speaker. It can be quite dull at times, and the guest speaker is not specified here, so it could be from a boring historian to an endurance rider who is filled with exciting stories.
So, it is most likely not answer choice 1.
The benefits of regular exercise is most likely a speech meant to inform, not to entertain.
Why people should vote for a political candidate is a persuasive speech.
So, the best answer may be "the best thing about being a twin".
