user_prompt: ## Instruction:
  You enter a room (Zone 1) that contains a button on the floor. Zone 1 also contains a blue path that can be activated by pressing the button in Zone 1. 
  
  Zone 2 is located to the right, elevated in the air above the water. It features a piece of white wall, and across from it, there is a slot that can be activated by directing a blue path into it. 
  
  The blue path slot in Zone 2 is linked to a shield wall that separates Zone 1 from Zone 3. Zone 3 is also elevated and cannot be reached by walking from Zone 1. Zone 3 contains a cube and has a white wall piece that can be used for portals. 
  
  Across the water, where Zone 2 is located, there is Zone 4. Zone 4 is separated by a shield wall, which is connected to a button within Zone 4. Zone 4 also contains a blue path that directs into a white wall piece. The exit door is located in an elevated position within Zone 4.
  
  Below is a candidate solution:
  Step 1: Enter the room.
  Step 2: Shoot an orange portal on the white wall on the left (Zone 1) and a blue portal up on the white wall in Zone 3.
  Step 3: Step on the button, which will create a blue path that will touch the blue path slot over the water on the right (Zone 2). This will remove the shield wall to Zone 3.
  Step 4: Shoot a blue portal on the white wall piece in Zone 3 and enter the orange portal to collect the cube in Zone 3 and bring it to Zone 1.
  Step 5: Place the cube on the button in Zone 1, and shoot a blue portal on the white wall in Zone 2.
  Step 6: Walk through the orange portal from Zone 1 to Zone 2 and continue walking to the end of the path in Zone 2.
  Step 7: The activated path slot in Zone 2 allows you to shoot a blue portal in the white wall of Zone 3, which lets you drop from the path in Zone 2 onto a new path coming from Zone 3 at a 90-degree angle to the previous path.
  Step 8: Walk along the path over to Zone 4.
  Step 9: Step on the button in Zone 4 to remove the shield wall and shoot a blue portal at the wall in Zone 2 and an orange portal at the white wall of Zone 4.
  Step 10: Walk through the orange portal onto the path in Zone 2 until you are aligned with the white wall of Zone 3. Shoot a blue portal in the white wall of Zone 3 (the cube is still on the button in Zone 1). This will let you drop to the new perpendicular path to Zone 3.
  Step 11: Walk on the perpendicular path (between Zone 3 and Zone 4) and jump off into Zone 1.
  Step 12: Shoot a blue portal in the white wall on the right of Zone 1 and collect the cube from the button in Zone 1. Bring it through the portal to Zone 4.
  Step 13: Place the cube on the button in Zone 4, which removes the shield wall of Zone 3.
  Step 14: Shoot a blue portal in the white wall of Zone 2 and walk into the orange portal.
  Step 15: The activated path slot in Zone 2 deactivates the shield wall of Zone 3, allowing you to shoot another blue portal at the white wall of Zone 3 while standing on the path in Zone 2.
  Step 16: This lets you drop onto the perpendicular path from Zone 3 to Zone 4.
  Step 17: Walk along the path to Zone 4 and enter the open exit door. Problem solved.
