You are the ruler of a medieval empire and you are about to have a celebration tomorrow. The celebration is the most important party you have ever hosted. You’ve got 1000 bottles of wine you were planning to open for the celebration, but you find out that one of them is poisoned.
The poison exhibits no symptoms until death. Death occurs within ten to twenty hours after consuming even the minutest amount of poison.
You have over a thousand slaves at your disposal and just under 24 hours to determine which single bottle is poisoned.

What is the smallest number of prisoners you must have to drink from the bottles to be absolutely sure to find the poisoned bottle within 24 hours?

Grundi, Yomi and Rafi, gathered for an intraplanetary
conference to discuss the problem of the visiting Earthlings.

were Aken, Bal, Mun and Wora.

with Mun.
2. After debating with the Martians in the blue and
the brown feathers, Bal and the Yomi were so angry
