Since both people are deaf and you can’t speak or write, you need to use a non-verbal action that forces them into a logical reaction.
Here’s what you do:
Point to one door (let’s say Door #1).
Wait for them to react.
Then, point to the other door (Door #2).
Why This Works:
If the Truthful Person is pointing at Door #1:
The Liar will point to the opposite door (Door #2) because they always lie.
The Truthful Person will confirm that Door #1 leads to salvation.
If the Liar is pointing at Door #1:
The Truthful Person will point to the opposite door (Door #2), because they tell the truth.
The Liar will try to lie and point to Door #2.
Key Insight:
No matter which door you start with, by observing the two people’s reactions, you can deduce which one is telling the truth and which one is lying, because their reactions will always contradict each other.
Final Answer:
Choose the door the Truthful Person is pointing to.
You’ve successfully outwitted them and secured your salvation! 😈
