You are hostaged and standing at the top of the building, the man whom has you hostage says "tell a truth and you shall be stabbed, tell a lie and you'll be pushed off the building", what do you say?

I’d whisper “What is a truth and what is a lie? How would one know such an answer because what is true to one person is false to another. A woman in Brazil once gave birth to 8 sons at the same time while another 12 at the highest mountain in Topeka. Which is true and which is a lie if it’s just a rumor?”

Firstly, by whispering you are not telling the person the answer, you are whispering it. Secondly, what is a truth and what is a lie? It depends on who you ask if something is true or a mere lie.
