Nico is giving an oral presentation about the benefits of adopting a pet from a shelter. he makes eye contact with his audience throughout the presentation, glancing at his notes only occasionally. when he is showing pictures of kittens and puppies that are up for adoption, he raises his voice and speaks more quickly. he uses a chart to show all of the different animals in need of homes in his area, and he provides a brief bulleted list of all the reasons why students should not support pet stores. before answering questions at the end, he shows a photo of his dog, a terrier that his family rescued. what could nico have done to make his oral presentation more effective? -he could have stopped himself from showing a photograph of his pet at the end. -he could have spoken at a steady pace and volume throughout the presentation. -he could have made less eye contact with the audience and looked more at his -slides. -he could have read his bulleted list out loud instead of showing it on a slide.
