Question
**Question 1**

The image contains a ring and barrier traffic signal diagram, divided into two rings (Ring 1 and Ring 2) and four phases. Each phase is numbered and shows permitted, protected, and pedestrian movements on Major and Minor streets.

**Diagram Explanation:**

- **Ring 1:**
  - **Phase 2:** Located on the Major Street, indicating permitted left turns, straight movements, and pedestrian crossings.
  - **Phase 3:** Positioned on the Minor Street, indicating permitted right turns, straight movements, and pedestrian crossings.

- **Ring 2:**
  - **Phase 5:** On the Major Street, showing permitted left turns and pedestrian crossings.
  - **Phase 6:** On the Major Street, showing straight and right-turn permitted movements.

**Symbols Legend:**

- Arrows represent the direction of permitted (dashed lines) and protected (solid lines) movements.
- Pedestrian movements are indicated by cross symbols.

**Question:**

In this ring and barrier diagram, which phases cannot be reversed in their sequencing?

- ☐ phase 1 and phase 2
- ☐ phase 5 and phase 6
- ☐ phase 1 and phase 5
- ☐ phase 3 and phase 4
