You're just asking a nasty question.
Your hypothetical tries to force us to choose between two exceptionally unpalatable courses of action. There is no way, within the survey, to express ones distaste of both alternatives. Which number is larger: a billion or a billion and one? Answer: they're both pretty huge though technically, a billion and one is bigger.
You might measure how much viewers select the third option, "don't answer" by the number of views compared to the number of viewers who vote. Even this only shows the proportion of your audience who can be so manipulated rather than just saying, 'fuck you.'
Fuck you

So how, exactly, does God know that She's NOT a brain in a vat?
