Tanisha says that the moon looks dark from earth when the moon is in 2 different places

She is wrong, this is because the moon is dark, meaning that the moon would have to be behind Earth and being blocked from sunlight. For example, if the sun is on the left, the Earth in the middle, the moon would have to be on the right, behind Earth. The moon is dark because the rays only are able to hit the Earth, due to the moon's position.
