1) Astronomers use different measurement systems to discuss distance in the universe C) because they allow the numbers to be more manageable.

The numbers are so huge that astronomers need different units to express them.

2) The measurement system with the largest value is C) the Parsec.

1 Parsec = 3.26 ly = 2.06 * 10⁵ AU
