Ok, given that you now have a possible answer, allow me to pretend ignorance for a moment and claim I don't understand why the projection of a join between a relation and the division of a projection of a selection of a relation and the projection of a relation is the answer to the question.

Can you provide your own explaination why the answer is or is not correct?
