The diagrams above show Earth and the Moon in different positions, as seen from above (top view). Sunlight is coming from the left, but these diagrams do not show what parts of Earth or the Moon are light or dark.
Could the half of the Moon that faces Earth ever be completely dark in any of these diagrams?

Tanisha says that the Moon looks dark from Earth when the Moon is in two different places: always when it is closest to the sun, as in Top View #1, and always when it is furthest from the sun, as in Top View #2.
Is Tanisha correct? If she is correct, explain why the Moon always looks dark from Earth in both of these positions. If she is incorrect, explain when the Moon looks dark from Earth and how the light on the Moon should look in each of Tanisha’s diagrams.
