What is a speaker doing when she uses evidence and examples to support her opinion?

When a speaker is using evidence and examples to support his o her opinion, the speaker is providing support to the statements he or she is making.

Explanation:

Whenever someone is introducing data or opinion in an oral or written speech, he or she will need to support this data or opinion by providing evidence -acquired as a result of a research conducted by himself or herself, or by a third person- and examples. These two elements will prove the credibility of the assertion made.

the purpose of a nonfiction text is to give the text a rap up. for example, when i say : frogs are interesting animals is an ending. then when i say: frogs are unique in different ways. that is an intro.
