user_prompt: ## Instruction:
  Upon entering the room, there is a left hall and one to the right. The left hall contains a cube slot, while the right hall leads to a button linked with a cube machine that produces a cube. Further ahead, there is a big hall with a platform on the left wall that can be elevated to reach a button at mid-height. Additionally, there is a button high up on the roof.
  The cube is in the cube slot, which elevates the platform to the button at mid-height.
  Pressing the button at mid-height activates the red beam that allows hovering over the rift.

  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. 
  A. Place cube close to the platform.
  B. Make a portal on the ground and one on the wall where the gravitation beam lands and get pulled into the beam to hover across the room.
  C. Press button on the right.
  D. While up in the air, create an orange portal at the white wall across the colored upwards tilted area close to zone 4 in order to jump out of it when falling down through the orange portal on the floor.
  E. Shoot the second portal under the cube. Then walk to the platform.
  F. Once the ball keeps flying, step on the red button on the floor to tilt the white area on the wall to the right. While the ball is falling (not inside a portal), shoot a new blue portal to the tilted area, such that the ball shoots out of there skewed across the room through the little hole in the wall.
  G. Stand on platform and shoot second portal under the cube so that it falls into the cube switch and platform where protagonist stands on lifts off.
  H. Shoot a blue portal inside the right room while standing on the button, then shoot an orange portal right next to the floor button and walk through the orange portal.
  I. Make portal close to the roof to press the topmost button on the roof (left close to entrance). This opens the final door.
  J. Make a portal on the white wall on the right that points to the exit door and let the beam push you from behind over the cliff to the exit.
