These are the questions used during the test to distinguish a human from a replicant (presumably, a human would become flustered at the thought of killing an animal, and a replicant wouldn't):
It’s your birthday. Someone gives you a calfskin wallet. How do you react?
You’ve got a little boy. He shows you his butterfly collection plus the killing jar. What do you do?
You’re watching television. Suddenly you realize there’s a wasp crawling on your arm.
You’re in a desert walking along in the sand when all of the sudden you look down, and you see a tortoise, crawling toward you. You reach down, you flip the tortoise over on its back. The tortoise lays on its back, its belly baking in the hot sun, beating its legs trying to turn itself over, but it can’t, not without your help. But you’re not helping. Why is that?
Describe in single words, only the good things that come into your mind. About your mother.
