From this BBC News article:
The wild Carneddau ponies of Snowdonia are a unique breed that need to be protected, say scientists
I was surprised to read need, expecting needs.
Why does it say a breed that need to be protected, and not a breed that needs to be protected?
In this sentence, I think that refers to breed, not to ponies. I'm aware that with British English collective noun rules, sport teams, companies, and probably some other groups, may get a plural verb even if they appear singular (Arsenal rule, BP have made profits, etc.). Does this apply to breed? Or is there a different reason why the verb in the cited sentence is a plural one?
