The diagram is looking down on Earth and moon positions from above.

1. Infer where the Sun is by the light hitting the Earth and moon positions in the diagram.
2. Look at a moon position and imagine what you would see when viewed from Earth. Touch Earth for a hint.
3. Drag the appropriate moon image on to that position. Repeat step 2.
4. When you're done, click the CHECK button.

HINT: Only the part of the moon inside the green ring is visible from Earth.
