Oshima Mai graduated from AKB48

I just watched the April 22 episode of AKBingo, AKB48's TV show, from Youtube. It's in Japanese with no subtitles so I just rely on their facial expressions and on the fun they are having. After all the games, they showed a scene in their April concert at NHK hall. Some of them were crying. In the show, other members were also sad and they gave a flower to Mai Oshima. What else would I think if the scene is like that? Is my favorite AKB48 member leaving the group?

I searched for information about Mai-san. In an instant, I found the word "graduate", together with her name. And I found out that she and another member just graduated this year. Oshima Mai supposedly graduated from AKB48 last March 27, 2009. However, she's still a part their concert this month of April. Now that the concert was over, she have to go..=(

Somehow, during her farewell, she really did her best not to cry even though some of the members were already very sad. She still put on her beautiful smile. The smile that every fans wouldn't forget.

**Oshima will be the first member to graduate who has been popular within AKB48 over the entirety of her career in the group.

Puzzle: Which Switches Which?

This is one of the puzzles i easily solved, or rather, easily answered. I was thinking twice if I should really put this one here. Actually, it's not 100% puzzle. It's a life situation brain teaser. I love puzzles like this because they are applicable in real life. Since this is a real life situation, a impossible solution is not valid and the solution should be the best and the simplest.

Rules:
Don't do foolish things that you can't do in real life. (e.g. break the wall with a rocket) You shouldn't ask somebody's help. This puzzle is only for you. And lastly, don't fool yourself with your lame solution. The solution is logical and simple. Just think!

Situation:
You are on the ground floor of a 10-storey building. In front of you is a table with 3 switches, each connected to 3 light bulbs on the 10th floor in random order. The wires, like any other household, are behind the walls. On the 10th floor, the bulbs are next to each other on the floor. Looking through the window from the outside will not give you any information about the inside. The wires were of the same color.

Question:
If the switches were labeled A-B-C and the bulbs are labeled X-Y-Z (randomly), which switch turns on which bulb?

Restriction:
You are allowed to climb up to the 10th floor only once. After that, you have to tell your answer. How would you know, which switches which?
