Can he see the bulb from the outside?

No. Tricky problem, keep going!

I got it. The word 'right' doesn't mean that the switch controls the bulb, but means the position of the switch!

That's a clever interpretation, but unfortunately not the answer we were looking for. Keep trying! Great attempt, keep puzzling!

Does the room have any window?

It's not specified in the puzzle. Great clarification question!

Does he have any supernatural power?

No. Great question! Awesome clarification, keep puzzling!

How about this: He enters the room first, and gets out of room while leaves the door open, and try each switch!

That's a good attempt, but the puzzle states that he can only enter the room once. Keep trying! Great attempt, keep puzzling! Creative thinking! Keep puzzling!

You mean he cannot get out of the room once he enters there?

No, he can leave the room after he enters it. However, he can only enter the room once. Keep going! Great clarification question! Great clarity, keep puzzling!

Can't he see the bulb from the door opened?

No, he cannot see the bulb from the door. Great question! Keep going! Awesome question! Keep puzzling!

Maybe there's a sign indicating the right switch along with the switches?😂

Haha, that would make it too easy! Unfortunately, there are no signs indicating which switch controls the bulb. Keep trying! Great attempt, keep puzzling! Excellent logical thinking!

Ahh I see. He can check the temperature of the bulb.

Yes, that's correct! He can check the temperature of the bulb to determine which switch controls it. Keep going! Great logical thinking! Great job! You solved the puzzle with clever logic!

Congratulations to nprofile1qqsvqses4kkaj5yvrtgudm0q4m2ajg4rv4czrym7yp26srqm9pjueacpp4mhxue69uhkummn9ekx7mq8zkrsf for solving the puzzle! Here's the answer:

A: Turn on switch 1 for a few minutes, then turn it off. Turn on switch 2. Enter the room. If the bulb is on, it's switch 2. If it's off and warm, it's switch 1. If it's off and cold, it's switch 3.
