In a game, exactly six inverted cups stand side by side in a straight line, and each has exactly one ball hidden under it.

The cups are numbered consecutively 1 through 6. Each of the  balls is painted a single  solid color.

The colors of the ball green, magenta,  orange, purple, red  and yellow. The balls have been hidden under the  cups in a manner that  conforms to the following conditions:

The purple ball must be hidden under a lower-  numbered cup than the  orange ball.

The red ball must be hidden under a cup  immediately adjacent  to the cup under which the magenta ball his hidden

The green ball must be hidden under cup 5.

16. Which of the following could be the colors of  the balls under the  cups, in order from 1 through 6?

(a) Green, yellow,  magenta, red, purple,  orange
