  D) Hot Jupiters have observed volcanoes; cold Jupiters do not.
  E) Hot Jupiters were an exciting discovery; cold Jupiters were not.

Question 2

If Jupiter were about 80 times more massive than it is, nuclear fusion should have been possible, making it a small star. What might have been the most likely effect on the Earth?
 
  A) The gravitational pull might have prevented the Earth settling into a stable orbit, which would have prevented the development of life on Earth.
  B) Jupiter's moons would have been likely to develop life, which would have competed with life on Earth.
  C) The extra radiation from a second star in the solar system would have prevented life forming on Earth.
  D) Jupiter's magnetic field would have been much larger, disrupting Earth's magnetic field.
  E) Nothing because Jupiter is so much further from the Earth than the Sun is.
