how long has he been working as one of the three tenors?

how long has he been separated with his first wife?

Вы уверены, что только должен быть past simple или PRESENT perfect?!

Даа

странно. потому что вопрос how long указывает на долготу процесса. А это уже present perfect CONTINUOUS. многие я бы сделала волбше в past perfect
