Happy New Year,
I wonder whether when can be used in these contexts:
Ex1: X could give positive results when interpreted differently. (here it is used like the word if)
Ex2: It was a stranger who helped Mike when his friends had forsaken him.
Ex3: This is more complicated: Here's the original sentence:
For John, the present week was better than the previous week - a week when he had faced a lot of trouble.
Could we avoid repetition and write: For John, the present week was better than the previous week when he had faced a lot of trouble.
Or, would 'where' be appropriate to show that John faced trouble the previous week?
When is fine in all of those.
