Can you explain why it's 'conobbi' instead of 'conosco'?"}, {"role": "assistant", "content": "S\u00ec, certo! The reason we use 'conobbi' instead of 'conosco' is because 'conobbi' is the passato remoto tense of the verb 'conoscere', which is used to describe a completed action in the past. 'Conosco' is the present tense, so it wouldn't fit in this sentence."}]
