Piper has been invited to give a presentation at the annual conference of biomedical engineering, a large gathering for industry professionals. She plans to talk about her research into the potential of artificial intelligence software to advance diagnostic practices. As she revises her speech for the third time, she makes sure she has fully defined many of the more technical terms so that no one will need to interrupt her to ask for clarification. However, she's concerned that her speech my go over the allotted time. Based on what you have learned about strategies for improving verbal communication, assess the strength of Piper's approach. a.) It's strong, because she has revised it several times. b.) It's strong, as long as she ensures that she doesn't exceed her allotted time. c.) It could be improved, because she is defining terms that are likely already understood by her audience. d.) It could be improved, because the topic is not suitable for the audience.
