Can you help me translate it?"}, {"role": "assistant", "content": "The translation of 'How can you be sure?' in Italian is 'Come puoi essere sicura?'. This sentence is used to express doubt or uncertainty about something, and the word'sicura' is the feminine form of the adjective'sicuro', which means'sure' or 'certain'. If you're speaking to a male, you would use 'Come puoi essere sicuro?' instead."}]
