On page 2 I read this:

"Clone the wider of the top two ellipses. Hold down the Shift key (to select multiple objects) and click on the wider ellipse and the wider of the two blue shapes. Combine Shapes > Add Shapes (Arrange menu)."

Having just made a clone of the wider of the two elipses, am I to now select the oridinal or the clone for the add-shapes move? And I have no idea what "the wider of the two blue shapes" refers to. Could you make this step clearer? Maybe a second arrow pointing to the second thing I'm supposed to select?
