Why did the Big Bang not produce heavier elements?
 
  A) They did, but radioactive decay caused these elements to disappear again.
  B) Too many high energy photons were present during the era of nucleosynthesis for heavy elements to form.
  C) By the time helium could survive, the temperature had become too low for heavier elements to form.

Question 2

Suppose the star Betelgeuse (the upper left shoulder of Orion) were to become a supernova tomorrow (as seen here on Earth). What would it look like to the naked eye?
 
  A) We'd see a cloud of gas expanding away from the position where Betelgeuse used to be. Over a period of a few weeks, this cloud would fill our entire sky.
  B) Because the supernova event destroys the star, Betelgeuse would suddenly disappear from view.
  C) Betelgeuse would remain a dot of light but would suddenly become so bright that, for a few weeks, we'd be able to see this dot in the daytime.
  D) Betelgeuse would suddenly appear to grow larger in size, soon reaching the size of the full moon. It would also be about as bright as the full moon.
