Flatworms (apart from the turbellarians, (planarians are in the class turbellaria)) are parasitic and don't need complex nervous systems. A parasitic animal devotes much of itself to reproduction and doesn't worry about other tasks. Cestodes don't even have a gut, they absorb food via diffusion through their skin. Annelids are free-living animals, and they need to move around more. They don't spend their adult life hooked to the inside of an animal, they move around, and need a more complex nervous system to give them a better view of their world.

In diagram A, we can see that the light comes from the left, it first impacts on the Earth, and then we have the Moon.
Now, you can model this situation with a flashlight (the Sun) a basketball (the Earth) and a tennis ball (the Moon)
When you point with the flashlight at the basketball, the basketball will look bright, but it will cast a shadow behind it. This shadow will cover the tennis ball, and almost no light will reach the tennis ball, so it will not look bright.
This phenomenon is called a lunar eclipse, and this happens when the Earth is in between the Sun and the Moon. When this happens, we see the moon a bit darker and more reddish.
