Four books are stacked vertically. The Red book is directly above the Blue book. The Green book is somewhere beneath the Yellow book. The Blue book is directly above the Green book. What is the order of the books from top to bottom?
Yellow, Red, Blue, Green
Blue is above Green. Red is above Blue (so Red, Blue, Green). Yellow is somewhere above Green, and since Red is above Blue which is above Green, Yellow must be at the very top to be above all of them. Order from top: Yellow, Red, Blue, Green.
