How do bipolar jets relate to lobe radio galaxies?
 
  What will be an ideal response?

Question 2

What do we mean by the main-sequence turnoff point of a star cluster, and what does it tell us?
 
  A) It is the spectral type of the hottest main-sequence star in a star cluster, and it tells us the cluster's age.
  B) It is the mass of the most massive star in the star cluster, and it tells us the cluster's size.
  C) It is the point in a star cluster beyond which main sequence stars are not found, and it tells us the cluster's distance.
  D) It is the luminosity class of the largest star in a star cluster, and it tells us the cluster's age.

Answer to Question 1

Answer to Question 2

A
