You are visiting an island and need some information. The island has liars, truth-tellers, and togglers. Critically, togglers alternate truths and lies in their answers. When you meet someone, how can you tell if they are a liar, a truth-teller, or a toggler with just one question?
It seems to me that the question needs to be met with yes, no, or no answer respectively. However, I haven't been able to find a question that satisfies this condition.
