I want to know the answer to the following question:
What cities saw an increase in foreign trade of more than 40% in 2008?
All the background I'm provided with is that "Chengdu, Suining, Nanchong, Dazhou, Ya'an, Abazhou, and Liangshan all saw an increase of more than 40 percent while Leshan, Neijiang, Luzhou, Meishan, Ziyang, and Yibin saw an increase of more than 20 percent.". Is that enough to answer the question?
