Sunrise...or sunset? Can you tell the difference?

this is the sunset part of our quiz.



this is the sunrise part of the test!

These are two pictures from the beautiful Riviera Maya.  We stayed at the Barcelo Maya Tropical/Colonial.  It was breathtaking. 
I should add that this sunrise picture?  Earlier than I have gotten up ever, except when I was in labor with one of the kids, or studying for a test, or writing, or playing on facebook, or something silly like that.
