What is the only question you can't answer yes to?

I think there’s various questions which can not be answered as “yes.”
For example, one can’t answer yes to “Are you immortal?” “Are you going to live forever”
This is due to the fact that of course humans are not immortal!
But besides this question, there’s many more that can not be answered as yes. It can not be just one.
