which is one piece of information that astronomers use to calculate the age of the universe?\n○ dark energy\n○ the age of rocks on earth\n○ the current motion of inner planets\n○ patterns of background radiation

Answer

Brief Explanations:

Cosmic microwave background radiation patterns give insights into the early - universe conditions and are used in calculations related to the age of the universe. Dark energy affects the expansion rate but not directly for age - calculation in the same way. The age of Earth rocks is much younger than the universe. The motion of inner planets is related to gravitational dynamics and not to the age of the universe.

Answer:

D. patterns of background radiation
