This weeks Weekend workout (A Lovely Encounter 31-09-2018) asks for a translation of 'She had just closed her eyes when she heard a little squeal comming from the bushes.'
For the 'when she heard' section I answered: 'quand elle a entendu' but the answer was given as 'quand elle entendit' (passé sample).
Could you please explain why "quand elle a entendu" is incorrect.
