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.
  
  Select the correct options for each blank. Only output option letters one by one, with the format '{Option 1}{Option 2}{Option 3}{Option 4}{Option 5}, such as 'ABCDE'
  Step 1: Enter the room.
  Step 2: ________
  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: ________
  Step 5: ________
  Step 6: ________
  Step 7: ________
  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 4.
  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.
  
  Please select from the following candidate choices. Your response should end with "The final answer is [answer]." where the [answer] is the choice of options.

  G. 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.
  H. Shoot an orange portal on the white wall on the left (Zone 1) and a blue portal up on the white wall on the right over the water (Zone 2).
  I. Walk through the orange portal from Zone 1 to Zone 2 and continue walking to the center of the path in Zone 2.
  J. Place one ball in the yellow slot to open the yellow chamber. Enter the chamber, lift up the robot, bring it through the portal, and lay it on the floor so it can shoot at you.
