Despite an expensive publicity campaign, ticket sales for the new play were poor enough that it closed only after two weeks.
poor enough that it closed only after two weeks
poor enough that it was closed after only two weeks
so poor that it closed only after two weeks
so poor that it was closed after only two weeks
so poor that only after two weeks it closed

A part of the explanation says: Note that the correct answer does change the verb from active to passive voice ("it was closed"), which is generally slightly less preferable
My question is:
1. why is the passive voice 'slightly less preferable'? Active voice would have sounded like this ''Despite an expensive publicity campaign, ticket sales for the new play were so poor that it closed after only two weeks''. After all, the play cannot close itself.
2. Why is the 'it' not considered ambiguous?
It seems to me like 'ticket sales' is the subject. So, isn't it possible that 'it' refers to 'ticket sales'?
Thanks,
