Hello everyone,

when talking about past time is is true that we always have to use the simple present when we ask a question with "when" and the present perfect in a question with "how long"?

ex: a) When DID you GO to the cinema?
b) How long HAVE they STAYED under the bridge ?’ ‘For half an hour.’

Can we say: ‘How long DID they STAY under the bridge ?’ ‘For half an hour.’ ??

Many thanks,
Hela
