Answer:
gesturing with open hands
Explanation:
Presentation can be defined as an act of talking or speaking formally to an audience in order to explain an idea, piece of work, project, and product with the aid of multimedia resources or samples.
Basically, any speaker who wish to create an effective presentation should endeavor to interact frequently with the audience by holding a conversation.
In communication, non-verbal cues such as posture, tone and gestures play a significant role in enhancing effective communication.
Gesturing with open hands would best help speakers indicate that they are receptive to new ideas. A speaker should spread his or her hands apart with the palms slightly facing the direction of the audience. This gesture typically indicates the willingness of the speaker to receive new ideas.
