Answer:
3. He should encourage audience participation by asking questions or requesting examples.
Explanation:
When an audience is not engaged in a speech it means that they are not interested in the contents of the speech or rather the way contents have been presented.
The purpose of a speech is to impart knowledge to a large group of people if the audience is not interested in the speech then the main function of a speech is not fulfilled. The speaker should not ignore the speech or provide additional data but instead, encourage the audience to participate. This would involve the audience in the speech.
Hence the answer is 3. He should encourage audience participation by asking questions or requesting examples.

Farmer joe only breeds the largest hogs, the fastest horses, or the cows that give the most milk. this is an example of artificial selection.
The process by which humans select individual organisms with specific phenotypic trait values for breeding is known as artificial selection. If the selected trait has additive genetic variance, it will respond to selection, i.e., the trait will evolve. All of our domesticated species, including crop plants, livestock, and pets, are the result of selective breeding for desirable traits such as hardy seeds and fruits, increased meat and milk production, and docile behavior.
Although the earliest artificial selection was unintentional, it evolved into a sophisticated science of plant and animal breeding; indeed, much of the field of quantitative genetics was developed to improve breeding programs.
