It looks like we're still figuring out - this room was just renovated, we're still working out exactly how the electronics work. So normally we'll see a percentage of how many of you got it, but I'm going to say it was probably about 95% got the answer right.

这个房间刚刚装修过,我们还在试图搞明白，这些线路怎么工作的,如果正常的话,我们可以看到，你们回答正确的百分比，但我觉得你们,95%的人答对了。
