ESL/EFL Test "Responses (5)", answer 7

Jill: 'I don't think I can stand much more of this.'
Frank: 'The worst is over.'

Correct answer: (c) The worst is over.

Your answer was: incorrect
Jill: 'I don't think I can stand much more of this.'
Frank: 'The worst is through.'
_________________________

'I don't think I can stand much more of this.'

The Kind of response that is associated with the statement is to sooth the person and it is still not over.. So, in my View i feel " The worst is through " might be apt.. Guide me if i'm wrong.

Over and through have the same meaning (= finished, completed), but the stock phrase in English is the worst is over.

Hi! In tests as answeres very often are used idioms. If I understand right only right one is existing and other three don't exist? Or they can be used with other sentences?
Thank You.
P.S. Sorry, for mistakes. I would be happy if you correct it.

Sometimes they don't exist and sometimes they are other idioms.
