Logic Level 2

There are two doors $$\text A$$ and $$\text B$$, and two individuals are before the doors. One door leads you to $$\text{treasure and happiness}$$ while the other leads you to $$\text{sadness and misery}$$

• One of the individual always lies, while the other always tells truth.

• You are supposed to ask only one question to any one person.

Can you get to the door containing $$\text{treasure and happiness}$$?

If you think there's a way out, provide a solution as to what question you would ask. If you think there's no way out, provide a proof explaining why. And if you think that the data is inadequate, explain what should be added to the question.
