W: A corporate bond rated Aaa
X: A corporate bond rate Baa
Y: A corporate bond rated Aaa with a shorter time to maturity than bonds W and X
Z: A corporate bond rated Aaa with the same time to maturity as bond Y that trades in a more liquid market than bonds W, X, or Y
List the bonds in the most likely order of the interest rates (yields to maturity) of the bonds from highest to lowest. Explain your work.
