I want to know the answer to the following question:
What did researcher Geng Qingguo say was sent to the State Seismological Bureau?
All the background I'm provided with is that "Malaysia-based Yazhou Zhoukan conducted an interview with former researcher at the China Seismological Bureau Geng Qingguo (耿庆国), in which Geng claimed that a confidential written report was sent to the State Seismological Bureau on April 30, 2008, warning about the possible occurrence of a significant earthquake in Ngawa Prefecture region of Sichuan around May 8, with a range of 10 days before or after the quake.". Is that enough to answer the question?
Answer: yes
