Safety from the queen (Posted on 2002-12-12)

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)

Place the five queens on squares E5, E4, E3, D3, and C3. Then, place the five pawns on squares B1, A2, and A4.
