[{"role": "user", "content": "I'm learning about different ways to express admiration for someone's work ethic in Italian, so can you help me translate the sentence 'He worked hard' into Italian?"}, {"role": "assistant", "content": "The translation of 'He worked hard' in Italian is 'Lui lavor\u00f2 duramente'. This sentence is in the passato remoto tense, but in informal conversations, you might use the passato prossimo tense, which would be 'Lui ha lavorato duramente'. Both are correct, but the usage depends on the context and the region in Italy."}]
