As part A moves to the left, gear C will turn

  1. Faster than gear A

  2. First in direction 1 and then in direction 2

  3. In the same direction as gear B

  4. Slower than gear B

The correct answer is: Faster than gear A

As part A moves to the left, gear C will turn faster than gear A because two gears that are connected and turning in opposite directions will be rotating at different speeds. The speed of gear A may dictate the direction of gear B but gear C will move faster in relation to gear A's movement. Option B is incorrect because part A's movement to the left will not make gear C turn in two different directions. This would require the gear to change its rotation halfway through, which is not possible. Option C is incorrect because gear B will turn in the opposite direction of gear A and not in the same direction as gear B. Option D is incorrect because since gear B turns slower than gear A, gear C will also turn slower than gear A.
