Examples of mirror and water reflections are shown in the figures below:

An object appears as the following image after first reflecting in a mirror and then reflecting on water:

The original object is:

A
B
C
D
Step 1: Understand the transformation sequence.
The object undergoes two distinct transformations: Mirror reflection: A horizontal flip of the original object. Water reflection: A vertical flip of the mirrored object. Step 2: Reverse the transformations.
To find the original image, reverse the transformations step by step: Reverse the water reflection (vertical flip) applied to the final image \(5:24\), resulting in: \[ 4:25 \] Reverse the mirror reflection (horizontal flip) applied to \(4:25\), resulting in: \[ h2:5 \] Step 3: Confirm the result.
The original image before any transformations is:
Final Answer: (1)
Eight students (P, Q, R, S, T, U, V, and W) are playing musical chairs. The figure indicates their order of position at the start of the game. They play the game by moving forward in a circle in the clockwise direction.
After the 1st round, the 4th student behind P leaves the game.
After the 2nd round, the 5th student behind Q leaves the game.
After the 3rd round, the 3rd student behind V leaves the game.
After the 4th round, the 4th student behind U leaves the game.
Who all are left in the game after the 4th round?
