Answer:
The speaker uses evidence to support her point of view.
Step-by-step explanation:
When a speaker justifies her point of view, this means that she is providing evidence to support the argument that she is making. Although opinions are not facts, and they are not right or wrong, they can be more or less justifiable. This means that some opinions are better backed up by evidence. Therefore, it is always useful to provide concrete evidence when we want to justify a particular position we have.
