My friend and I are discussing the following task from our English exercise book.
Finish each of the following sentences in such a way that it means the same as the sentence printed before it.
The prince began choosing his wife a week ago.
=> The prince has ___.
My friend wrote her answer as below:
The prince has chosen his wife for a week.
For me, her sentence sounds awkward because 'to have chosen' is an action that seems to happen very quickly, not over a period of time. So, I suggested another sentence to my friend:
The prince has not decided his wife for a week
Is my explanation correct and if my rewritten sentence doesn't sound fine, please could you suggest a better one?
