Step 1: Analyzing the structure of a bathing mug.
- The mug generally has a cylindrical or slightly tapered body.
- A curved handle is attached to one side to facilitate grip.
Step 2: Sketching the hand holding the mug.
- The fingers and thumb should naturally wrap around the handle.
- The grip must be proportionate to the size and shape of the mug.
Step 3: Depicting material characteristics.
- The mug can be made of plastic, metal, or stainless steel.
- Apply texture details and reflective highlights based on the material properties.
Step 4: Enhancing realism.
- Utilize shading techniques to create depth and form.
- Include cast shadows of the mug and hand to indicate light direction.


Let $ P(x_1, y_1) $ and $ Q(x_2, y_2) $ be two distinct points on the ellipse $$ \frac{x^2}{9} + \frac{y^2}{4} = 1 $$ such that $ y_1 > 0 $, and $ y_2 > 0 $. Let $ C $ denote the circle $ x^2 + y^2 = 9 $, and $ M $ be the point $ (3, 0) $. Suppose the line $ x = x_1 $ intersects $ C $ at $ R $, and the line $ x = x_2 $ intersects $ C $ at $ S $, such that the $ y $-coordinates of $ R $ and $ S $ are positive. Let $ \angle ROM = \frac{\pi}{6} $ and $ \angle SOM = \frac{\pi}{3} $, where $ O $ denotes the origin $ (0, 0) $. Let $ |XY| $ denote the length of the line segment $ XY $. Then which of the following statements is (are) TRUE?
