I guess it's very diffcult thread to understand.
For example: What is correct?
1. San Antonio Spurs has/have a good teamplay. Both "has" and "have" are possible in BrE. It's not a natural sentence, though.
2. The United States is/are a the champion/champions. Both are possible in BrE.
3. The Beatles is/are well-known music band. As above
4. Russia is/are the widest country in the world. Only "is" is correct.
I suppose both are correct, but I'm not sure.
Is there a difference between BrE, AmE, AuE in this case?
Thanks in advance.
