"May I please have one of those biscuits?" asked Alice rather timedly, rather taken aback by the sight of her present company.
"A biscuit?? Oh, I don't know. Those are the March Hare's special un-birthday biscuits, don't you know. Can she have a biscuit, March ?" asked the Hatter.
"A biscuit?? One of mine? Hurmph. Ok, I'm thinking of an integer from one to three (inclusive). If you get it, you can have a biscuit. If not, I'm afraid you'll just have to leave" said the March Hare, leaning back.
"Oh goodness, I don't know" said Alice worriedly. "Couldn't I just get a hint?"
"Oh, all right..." the March Hare sighed. "You get to ask me one yes-or-no question, that's all"
Alice thought for a moment, then smiled, knowing exactly what to ask.
What question should Alice ask?
