No that doesn't mean anything. Tests and books can be wrong.
Well, part of the coursework, and probably the hardest part, is about translating natural language problems into formal logic statements, ie:
"The liar says All my hats are green" becomes "¬∀x|x∈hat,OWNS(x) (GREEN(x))" or similar.
And then from there you can also translate the five provided answers and try to find a contradiction.
