Modify the given structure of the product to draw the required Robinson annulation starting materials as neutral compounds. Note: the eraser tool can be used to erase bonds, and atoms can be moved by selecting them with the selector tool and then dragging the selected atom(s) to a new position. If you make a mistake, you can use Ctrl-Z or the Undo tool.
