It would be great to ask the student to rewrite all statements in pure english. Then it's quite obvious, otherwise the counterexamples look like magic.

Is it fair then to say your qualm is more with the hint than the solution?

Or what else would you like in the solution if you were learning from these?

Yes, great. Extended hints solve this problem.
