Most of the planets discovered around other stars have masses comparable to the terrestrial planets in our own solar system.
 
  Indicate whether the statement is true or false

Question 2

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

A cataract is a clouding of the eyes' natural lens. As we age, some clouding of the lens may occur. The first sign of a cataract is usually blurry vision. Although glasses and other visual aids may at first help a person with cataracts, surgery may become inevitable. Cataract surgery is very successful in restoring vision, and it is the most frequently performed surgery in the United States.
