Reversible or Irreversible

I have the last edition of the textbook, and one of the questions describes a situation in which 40.0 heat energy is transferred from a large reservoir at 800.K to one at 200.K. It then asks for the entropy change. With so little detail provided, how can I tell if this heat transfer is reversible or not?
