Annotated Bibliography Assignment

I’m trying to study for my Communications course and I need some help to understand this question.

Annotated Bibliography Assignment

Create MLA Annotated Bibliography using just one source, answering these questions : What is the main point of this source?” and evaluative, “How can I use this source in my speech?”

I uploaded a sample for this assignment and I just need one source, not three.
