Question 2

In general, when we compare the mass of a galaxy or cluster of galaxies to the amount of light it emits (that is, when we look at it mass-to-light ratio), we expect that
 
  A) the higher amount of mass relative to light (higher mass-to-light ratio), the lower the proportion of dark matter.
  B) the higher the amount of mass relative to light (higher mass-to-light ratio), the greater the proportion of dark matter.
  C) the amount of light should be at least one solar luminosity for each solar mass of matter (mass-to-light ratio less than or equal to 1).
  D) the higher the amount of mass relative to light (higher mass-to-light ratio), the older the galaxy or cluster.
