Its trivial to get ChatGPT to reason about things:

Me: A room contains a blue box and a red box. Alice stands on the red box. Bob also stands on a box. No box has multiple people standing on it. Which box is Bob stood on?

ChatGPT: There are two boxes in the room: a blue box and a red box. Alice is standing on the red box, so Bob must be standing on the blue box. Therefore, Bob is standing on the blue box.

Me: Add a green box to the room. Which box is bob standing on?

ChatGPT: If a green box is added to the room, then there are now three boxes: a blue box, a red box, and a green box. Since Alice is still standing on the red box, we know that Bob must be standing on either the blue box or the green box. We cannot determine which one Bob is standing on without additional information.
