The mobility of a pin curl is determined by the?

1. Stem

2. Base

3. Circle

4. Loop

The correct answer is: Stem

A pin curl's mobility refers to how easily or fluidly the curl can move. In order for the curl to have good mobility, the stem must be flexible and pliable. This allows the curl to easily move and shape itself according to the desired style. The base, circle, and loop are all important parts of the pin curl, but they do not directly impact its mobility. The base provides the foundation for the curl and gives it its shape, while the circle and loop are used to secure the curl in place. However, the stem is what ultimately determines the curl's mobility. If the stem is not flexible, the curl will be stiff and not able to move as much.
