Why can’t the sky fall?

The sky is a plane, and does not have a mass, therefore there is nothing to fall

C- a hypothesis or d- an observation

You should provide a picture to show where the arrow is pointing and which information that is given. but there are 3 branches of the government, legislative, executive, and judicial. legislative makes laws, executives pass laws, and judicial are the courts
