Read this excerpt from "Why Are They Called Black Holes?"
After many millions or billions of years, the star runs out of hydrogen and energy. Then the star "dies" and collapses into a dense little ball with tons of gravity. Albert Einstein’s theory of relativity predicted that black holes would have to exist if a dead star had enough gravity. Using Einstein's theory, astronomers calculated that if a star more than three times as heavy as our sun died, the force of gravity pulling matter in could overwhelm any other force pushing matter out.
In this excerpt, the author makes a connection between a scientific theory and
the calculations that scientists make.
the beginning of a star's existence.
the idea that all things live and die.
the question of why gravity exists.

Read the claim. human bodies have developed over time to support a vegetarian diet. which sentence provides the best supporting evidence for the claim? because humans have evolved over millions of years, it makes sense that our diet has evolved as well. i can feel the negative effects of meat and its excess vitamins when i consume meat products. the length of human intestines is better suited to digest food derived from plants than to digest meat. human taste buds have matured throughout history in a way that makes people crave the flavor of meat.
