Perhaps her final answer was the only one she had left.

For me there is no such thing as a final answer.

And if the final answer is no, try to turn it into a learning experience.

I never thought that by myself, I'd come up with the final answer.

As of today, we still don't have a final answer.

As a side effect, once a final answer has been given, it cannot be changed.

We won't know the final answers to these questions for a long time.

And also in Season 2, the final answer of every question will go away like the wrong answers.

Right,so over here then, do you think that's your final answer?

In five minutes I shall return for your final answer.
