Question 2

Why is a dense cloud more likely to produce an elliptical galaxy than a spiral galaxy?
 
  A) The higher density of gas has a stronger force of gravity, and therefore the cloud collapses more quickly.
  B) The thickness of the dense cloud prevents a disk from forming.
  C) The higher gas density forms stars more efficiently, so all the gas is converted into stars before a disk can form.
  D) The force of gravity can pull the material into a more spherical shape.
  E) The more frequent collisions between particles randomize the particle orbits.
