I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "The economy is a mixture of village agriculture and handicrafts, an industrial sector based largely on petroleum, support services, and a government characterized by budget problems and overstaffing. Petroleum extraction has supplanted forestry as the mainstay of the economy. In 2008, oil sector accounted for 65% of the GDP, 85% of government revenue, and 92% of exports. The country also has large untapped mineral wealth."? 

What, in 2008, did the oil sector have a greater numerical impact on: exports or government revenue?
