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?

She is wrong.

Explanation:

The reason why she is wrong, is because the moon is dark, when its on the opposite side of earth. Lets say the sun is on the right side, the moon would be on the left. While the sun covers one half of the earth, the moon covers another half.
