Question

During Domenica’s oral presentation about the history of horror movies, she read from her notes often. She also showed clips from three films, commented on each one, and she provided photographs of several famous directors. After the presentation, she took questions from the audience. She didn’t know the answer to one student’s query, so she referred him to a website that she had used during her research.
What could Domenica have done to make her oral presentation more effective?

She could have looked at her note cards only occasionally.
She could have provided longer clips from each horror film.
She could have pretended to know the answer to the question.
She could have stopped herself from commenting on the films.

Answer 1

She could have looked at her note cards only occasionally.
She could have provided longer clips from each horror film.I believe these are the two possible answers to make her presentation more effective and no I don't think that pretending to know the answer to the question is right ie that would not be acting with integrity or being modest. I think it is just as important to know what you don't know as it is to know what you know. That way, you can direct people to those who know or to references. 

Answer 2

A is correct

She could have looked at her note cards only occasionally.
