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)

Queens would be located at: A2, A3, C1, D1, and D2.

Pawns that would be safe would be at: B5, E4, and E5.
