Question
Stars are formed from large clouds of matter that include gas and dust. The clouds have a low density and include elements such as hydrogen and helium, which have few protons and neutrons in their nuclei. Over a long period of time, the matter is pulled together by gravitational forces. Eventually, the matter collapses into ball and a star is born.
What does this information provide evidence for?
A.
It provides evidence that galaxies are formed from clusters of stars pulled together by gravitational forces.
B.
It provides evidence that the elements in the universe are created by reactions that occur within stars.
C.
It provides evidence that stars of all sizes go through the same distinct phases of change over similar amounts of time.
D.
It provides evidence that there was once a period of rapid expansion in the universe when matter was spread far apart.

The description that stars formed from low-density clouds made mostly of hydrogen and helium (few protons/neutrons) and that matter was originally spread out before gravity pulled it together supports the idea of an early rapid expansion (the Big Bang) when matter was widely dispersed.
