Consider a 5 by 5 Chess Board. Is it possible to place 5 Queens on the board such that three pawns can safely be placed on the board? (aka, by carefully choosing where to place the 5 queens, can you arrange it so that there are 3 squares on the board that none of the queens can attack)

(In reply to solution by logischer Verstand)

if you do that then it only leaves 1 space open.
