Final answer:
The bottom of the slide and the stage need to be dry to prevent slipping, ensure safety, and maintain good performance.
Step-by-step explanation:
The bottom of a slide and the stage need to be dry for several reasons:
- Friction: When the bottom of the slide and the stage are dry, there is more friction between the surfaces. This helps to prevent the person or object from slipping and falling during the activity.
- Safety: A wet surface can be slippery and increase the risk of accidents. Keeping the bottom of the slide and the stage dry ensures a safer environment for everyone.
- Performance: In sports shoes, dry conditions allow the proper grip and traction on the ground. Wet conditions can reduce the grip, affecting the performance of the shoes.
