To determine the answer, we can analyze the distances of the paper clips from the magnet based on the information provided:
- Clip W is at 1 centimeter.
- Clip X is at 4 centimeters.
- Clip Y is at 5 centimeters.
- Clip Z is at 7 centimeters.
Since the question states that only paper clips W and X moved toward the magnet, it implies that the magnet can effectively attract clips only within their distances.
The farthest distance at which any paper clip moves is 4 centimeters, which is the position of clip X.
Thus, the answer would be:
A. 4 centimeters away.
The magnet does not work well at picking up paper clips more than 4 centimeters away.
