In what location did I last see the blue set square?
On the wooden beam near the window.
Under the metal sawhorse.
On the edge of the wooden deck frame.
On the gray-red bricks, on the wooden board with the yellow-black drill, on the pile of gray bricks, on the ground next to the large wooden frame, on the ground next to the pile of gray bricks.
Next to the white bucket on the ground.
