I want to know the answer to the following question:
Under what category does oil and gas exploration fall?
All the background I'm provided with is that "In 2010, mining (which consists almost entirely of exploration and production of oil and gas in Houston) accounted for 26.3% of Houston's GAP up sharply in response to high energy prices and a decreased worldwide surplus of oil production capacity, followed by engineering services, health services, and manufacturing.". Is that enough to answer the question?
