Many of the elders had high education background, they understood the difficulty of the question. This question could be considered hard even for PhD students. Moreover the question was written in English. That was another hurdle for Wei Lan!
Even Jiang Yao was surprised, she had no idea if Mo Li could answer such an answer. "Li Li, since when did you study to such a high level? I haven't heard you mention anything about it before..."
"I found there is no need to gloat." Mo Li originally didn't even want to mention it. However, she needed to do something for her mother. Furthermore, the question was not that difficult for Mo Li, it was rudimentary quantum physics.
This was a question that demanded great logical thinking. As long as one's mind was clear and logically rigorous, one could answer it. The question was not intrinsically difficult, there were simply many tricks in it.
