If someone somehow added a lot more hydrogen and helium to the Sun (say 50 more than it has now), what would happen to it?
 
  A) Its nuclear reactions would slow down because its heavy element abundance would be relatively less.
  B) It would increase in size and float away.
  C) It would explode as a supernova.
  D) It would cease to exist as a star because it would be too diffuse and fluffy.
  E) It would begin to evolve much more quickly than it is now.

Question 2

  A) The planet's year would be longer than Earth's.
  B) The planet's year would be the same as Earth's.
  C) An orbit at a distance of 1 AU would not be possible around a star more massive than the Sun.
