Final answer:
Gear 3 is attached to gear 2, which rotates in the opposite direction of gear 1. Since gear 1 is rotating clockwise, gear 3 will rotate counterclockwise, and gear 4 will in turn rotate clockwise due to its meshing with gear 3. So, the correct answer is d) gear 3-clockwise-gear 4-counterclockwise, considering the typical behavior of interacting gears.
Step-by-step explanation:
If gear 1 is rotating clockwise, and gear 2 is attached to gear 3, we know that when two gears are directly meshed together, they rotate in opposite directions. Therefore, if gear 2 is rotating counterclockwise as a result of being attached to the clockwise moving gear 1, then gear 3, which is attached to gear 2, will also rotate counterclockwise because they are directly connected. Now, if gear 3 is rotating counterclockwise, then gear 4, which meshes with gear 3, will rotate in the opposite direction, which is clockwise. So, the correct answer is d) gear 3-clockwise-gear 4-counterclockwise, considering the typical behavior of interacting gears.
