Consider the question. Given the sentence "A man at a neuroscience booth addressing his audience." is it true that "No one is gathered in front of the booth."?
 If the answer is 'no'; explain the reasoning:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

If no one is at the neuroscience booth then there could not be an audience gathered there.
