Really nice board - the Physics degree's finally come in handy!

The “every” group can also be prefixed by “no”.

It was annoying that the "some" and "question" groups shared WHERE and WHAT. It was a random guessing game for these.

Sorry, but it doesn't work logically when multiple words are possible red herrings for the same two categories, because there has to be only one solution.
'Where' 'What' and 'How' are all question words, but they can also all follow 'some___', so they are interchangeable between those groups, and there are three correct grid arrangements.
