Question: How many mirrors are there in the scene shown in the picture? Please answer with a number (e.g. 2).
Clues:
1. A person is taking a selfie, which shows their reflection in a mirror they are facing.
2. A vertical line is visible on the reflective surface in front of the person, indicating a seam between two separate mirror panels.
3. A reflection of the person from a side angle is visible in the left mirror panel.
4. An infinite series of reflections, creating a tunnel effect, is visible in the main mirror panel.
5. The reflection in the main mirror shows the back of the person's head and the wall behind them, which is necessary for the infinite reflection effect.
