Question 1 (Duck): This sketch is unclear, even though there is a separate sketch to us how it looks like inside. It does not clearly show how the sketch is going to enable the duck to move in an oscillating motion. The sketch also has unclear lines, and I cannot tell if they are supposed to be erased or not.Question 2 (Table): The sketch is unclear, as the labels are hard to read. The lines that are supposed to be straight, are not straight and are un-proportionate, so I am also not sure how the sketch is suppose to look like originally before the add-ons. Linkages and locks are used in this sketch, but there is a lack of a second sketch to show how it looks like if the table is closed.
