Question 2

You discover a binary star system in which one member is a 15MSun main-sequence star and the other star is a 10MSun giant. Why should you be surprised, at least at first?
 
  A) It doesn't make sense to find a giant in a binary star system.
  B) The odds of ever finding two such massive stars in the same binary system are so small as to make it inconceivable that such a system could be discovered.
  C) The two stars in a binary system should both be at the same point in stellar evolution; that is, they should either both be main-sequence stars or both be giants.
  D) The two stars should be the same age, so the more massive one should have become a giant first.
  E) A star with a mass of 15MSun is too big to be a main-sequence star.
