Radio dishes are large in order to
 
  A) attract funding from NASA and the NSF.
  B) give greater magnification.
  C) increase their angular resolution and collect the very weak radio photons.
  D) increase the range of waves they can collect.
  E) detect shorter waves than optical telescopes for superior resolution.

Question 2

What factor caused different planets to form out of different types of material?
 
  A) The angular momentum of the forming planet; faster rotating planets lost the lightest elements.
  B) The quantity of dust particles in the solar nebula; more dust caused some planets to contain heavier elements.
  C) The variation in temperature throughout the solar nebula; the higher the temperature, the lower the percentage of light elements in the forming planet.
  D) The angular momentum of the solar nebula pushed the heavy elements towards the outer regions of the nebula.
  E) The innate variation of chemical composition of the original nebula; the outer parts of the nebula contained a greater abundance of heavy elements.
