1. D
The bottom figure is below the higher figure.
2. "E is nearest, "A" is furthest away.
3. 2 revolutions clockwise.
"C" (24 teeth) rotates 4 revolutions.Therefore "D" also rotates 4 revolutions.Pulley "B" has twice the circumference of pulley "D" and so will rotate 2 revolutions."C" rotates clockwise, as "B" does not change the direction of "C". Pulleys "D" and "E" also rotate clockwise.
