Ciara believes that whenever the Moon is in the position that is shown from above (top view) in Diagram A, the Moon always looks completely dark in the view from Earth, as shown in Diagram B. Is Ciara correct? If she is correct, explain why the Moon always looks dark from Earth in that position, and explain how she should show light on the Moon in Diagram A. If she is incorrect, explain how else the Moon can look when it is in that position.
