If wheel E rotates in the opposite direction of the clock's hands, which direction will wheel B rotate?

Question: If wheel E rotates in the opposite direction of the clock's hands, which direction will wheel B rotate?

Solution:
We know that when two wheels are connected by a crossed belt, they rotate in opposite directions.
And when two wheels are connected by a straight belt, both wheels rotate in the same direction.
When two wheels are directly connected, one will rotate in the opposite direction to the other.

In this case, If wheel E rotates opposite to the direction of the clock hands, wheel D will rotate in the direction of the clock hands.
If wheel D rotates in the direction of the clock hands, wheel C will rotate opposite to the direction of the clock hands.

Again, If wheel C rotates opposite to the direction of the clock hands, wheel B will rotate in the direction of the clock hands.
If wheel B rotates in the direction of the clock hands, wheel A will rotate in the direction of the clock hands.
