3) Here's a challenge:
There are 2 guardians at the crossroad of life... and 2 doors. One leads to death, and one leads to life... One guardian is always lying, and the other is always telling the truth.
What single question to ask so we get the correct answer which door leads to life, whoever we ask? You can ask that question only once. To one guardian only, of course.
Add on people.
