To the moderators, please.
I came across this sentence in 'English Grammar in Use':
_______a hotel, we looked for somewhere to eat. [Finding - After finding - Having found - We found] and the answer key of the book is 'After finding & Having found', which I completely agree with. Yet, why not 'Finding' as well.
Is it because as is mentioned in some grammar books to avoid ambiguity and to indicate that 'Finding a hotel' took place first, then it was followed (not immediately) by the second action, 'going somewhere to eat'?
