I don't know but I thought it this way


What if we announce a party for criminals and make the prisoners drink a sip from each bottle and number them accordingly, in that case, the answer could be just 1. I find it funny the way it’s even answered.


King wants to minimize the number of prisoners involved in the experiment. In your case, it would involve 1000 prisoners which can be reduced to 9 according to the solution.


@jewel-barman, very nice. I agree with your solution
