Five knights stand in a circle. Each knight wears a cloak that is either entirely crimson or entirely azure. Every knight makes a single statement: 'The knight to my immediate left wears azure.' If it is known that exactly three knights are telling the truth, what color cloak does the knight directly across from the liar wearing crimson wear?
Crimson
Since 3 knights tell the truth and 2 lie, and their statements are identical in structure, there must be a continuous block of true statements and a block of false statements. Tracing the only logical arrangement that yields 3 true statements reveals the exact distribution of crimson and azure cloaks, leading to the conclusion about the opposite knight.
