I choose "Battle to the Death" scenario 3.
The 2 excellent people win.
The logic leading to my conclusion:
The 8 idiots need waaay too much supervision and very direct, extremely detailed instructions, and hand holding, for death inducing origami to succeed.
Plus the normal person (aka the supervisor) will spend nearly all of their time setting up a work punch-in clock, and having to monitor coffee breaks, then have hire a service company to bring in coffee machines, to give them any instructions on origami. Once that's all done they'll have to set up a safety committee to discuss what to do in the event of nasty paper cuts, then train some first aiders and propose an emergency plan for catastrophic paper cuts, then bring in some consultants to run paper cut awareness training.
Then they'll all want performance reviewes and pay rises.
The two excellent people will use the internet, or even a public library and get some basic origami training. Then they'll go to an art / craft store and buy a selection of paper and make an arsenal of origami shurikens. The shurikens will then form the basis of a devastating cluster attack upon the 1 supervisor and 8 idiots who will be having a coffee break and complaining about their working conditions, so will be brutally slaughtered and not found until the beverage machine maintenance technician comes in to restock the coffee supplies.
Is that detailed enough for you?
