I want to know the answer to the following question:
What did  seismologist Gary Gibson have to say about the prediction of the quake?
All the background I'm provided with is that "In a press conference held by the State Council Information Office the day after the earthquake, geologist Zhang Xiaodong, deputy director of CEA's Seismic Monitoring Network Center, restated that earthquake prediction was a global issue, in the sense that no proven methods exist, and that no prediction notification was received before the earthquake.". Is that enough to answer the question?
Answer: no
