What is in this image? Be very specific. Scientific, Engineering style! No emotions, no opinions, no metaphors. Just the facts, as detailed as possible.

The image is a black and white line drawing, which appears to represent three human figures engaged in a curling game, a sport where players slide stones on a sheet of ice towards a target area. Each figure is distinctly illustrated in an action pose associated with the sport.1. **Human Figures** - **Figure 1 (left)** Positioned in a lunge with a left leg extended back, right knee bent, and leaning forward at the torso. This figure is holding a broom worn on one end, applied to the ice surface, commonly used to influence the path of the stone. - **Figure 2 (center right)** This figure is crouched slightly, holding a similar broom, and actively sweeping the ice in front of a curling stone. This action suggests the intent to adjust the friction between the stone and the ice surface, affecting the stone’s speed and curl. - **Figure 3 (top right)** Engaged in a dynamic pose with arms extended, one leg lifted backward, mimicking the action of releasing the curling stone. This figure is not in direct contact with any object in the scene, suggesting motion.2. **Curling Stones** - There are multiple stones depicted, distinguishable by their rounded shape and a handle on top which is typical of curling stones for gripping and rotating.3. **Playing Surface (Ice Sheet)** - The surface is demarcated by curved and straight boundary lines, including a hog line (dashed line near the figures) beyond which the stones must be released. The concentric circles, or "house," target the area where points are scored, are implied but not fully visible in the image.4. **Environmental Details** - The surrounding area includes what appears to be a segmented guardrail or wall in the background with angular and straight features. There is implied texture on the ice surface, represented by small dots and scratch-like lines
