2. It wasn't until last week that the Agriculture Minister admitted defeat.

Only last week did the Agriculture Minister admit defeat.
3. They didn't get round to business until they had finished eating.

Not until they had finished eating did they get round to business.
4. I didn't realize who he was until later.

Only later did I realize who he was.
5. I won't agree until Tom's apologized.

Only when Tom has apologized will I agree.
