Answer:
false.
Step-by-step explanation:
If referring to a speaker delivering a presentation based on arguments, evidence, and facts, all presented in the form of charts and figures, there is no amount of sincerity or charisma that would overcome being based on inaccurate or flawed facts nor presenting all these through defective or wrongly constructed figures. A presentation, as well as the arguments that it is based on, need all be accurate in order for it to be successful.
