I want to know the answer to the following question:
How long before the quake did Cyclone Nargis strike Burma?
All the background I'm provided with is that "The Economist noted that China reacted to the disaster "rapidly and with uncharacteristic openness", contrasting it with Burma's secretive response to Cyclone Nargis, which devastated that country 10 days before the earthquake.". Is that enough to answer the question?
