You wake to find yourself in a plain room with over 9000 doors opposite each other and a note on the table. Reading the note, you find that you have been selected for a scientific study into human psychology.
The note tells you that the experiment takes place over the next 20 years, and you may not leave until that time is up. It tells you to press button A to open room A or B to open room B. By opening one door, you permanently lock the other door. By pressing both buttons simultaneously, you permanently lock both.
Behind door A is a hemispherical room with radius twice your height, in which you would be constantly observed. If you enter that room, you may request, by speaking into the microphone in that room, to have an identical clone of any person you name or describe brought to you, including real life versions of fictional characters. The clone will obey whatever you command without question. You may switch your clone for another human once every month, but if you want to get rid of your clone you can kill it without any consequences. The clone CANNOT speak. It's like a zombie that can obey basic instructions like "bend over", "come here", "massage my feet" etc. The clone comes naked and won't obey any instruction to harm you.
You can also request as many inanimate, NON-ELECTRONIC objects to be brought to you as you want, as long as there is judged to be no way that you could use the item to kill yourself or escape. If you do attempt to kill yourself, you will be sedated and returned to your room, with the items you used permanently removed. (Remember that you can ask to have all the essentials brought to you whenever you want; a bed, meals, drink etc). You will be force-fed if you choose to starve yourself.
Behind door B is a gun and a bullet.
