I want to know the answer to the following question:
What percentage of buildings were destroyed during the quake?
All the background I'm provided with is that "The epicenter was in Wenchuan County, Ngawa Tibetan and Qiang Autonomous Prefecture, 80 km west/northwest of the provincial capital of Chengdu, with its main tremor occurring at 14:28:01.42 China Standard Time (06:28:01.42 UTC), on May 12, 2008 lasting for around 2 minutes, in the quake almost 80% of buildings were destroyed.". Is that enough to answer the question?
