"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?

If you want to be pedantic:-

"Alice puts her right hand behind her back.  She asks, "Is the number four less than the number of fingers up on my right hand, or is it a two?"  (This question is asked as a yes-or-no question, not a which-is-it question.)"

Alice has five fingers on her right hand (if you include a thumb as a finger) regardless of how many she is "holding".

Read your solution more carefully.
