For Nancy Duarte, the shape of a presentation is of utmost importance in order to convey a new idea and change the status quo. The shape of this presentation can be best described by the following metaphor:
A) The undulating "back and forth" motion of a ship at sea.
B) The rise and fall of a thermometer.
C) The unbearable cuteness of a kitten.
D) The dry heat of the desert and humidity of a jungle.
