Wouldn't accept cathedrals which was annoying

wouldn't accept rappers??

Yeah, seems like you forgot to type in keywords or something. "Rappers" doesn't work, and I put exactly "Dog breeds" which didn't work either despite the clue being exactly the same.

I'd have thought 'singers' would have been ok. Seems harsh

Poor. I got all of these right, but the answers weren't specific enough, so it told me I got them wrong (for example, writing "rappers" ends up saying "incorrect", even though it's clearly right - nobody is ever going to specifically answer "world famous rappers" as is specified).
