Question 1
Read the following passage and fill in each blank with words chosen from options given.
When a massive enough star runs out of fuel in its core and ______(1) the resulting Type II supernova will produce a black hole. Supernovae that aren't quite massive enough will produce neutron stars instead, which themselves will make black holes if they either ______(2) more matter or collide with another neutron star. But in theory, there should be a third way: through direct collapse. If a massive enough gas cloud collapses under its own gravity, it should form a black hole directly, without any ______(3) star. This is one of the leading theories for how supermassive black holes begin. If the ______(4) collapse is possible, we should see some massive stars with just the right properties ______(5) with no explosion. For the first time, astronomers observed a 25 solar mass star just disappear. Direct collapse is the only explanation possible which is now verified for the first time.Question 2
