Task: Question Answering
Input (English): Passage: Because of a boom in the mining sector, Mongolia had high growth rates in 2007 and 2008 (9.9% and 8.9%, respectively). In 2009, sharp drops in commodity prices and the effects of the global financial crisis caused the local currency to drop 40% against the U.S. dollar. Two of the 16 commercial banks were taken into receivership. In 2011, GDP growth  was expected to reach 16.4%. However, inflation continued to erode GDP gains, with an average rate of 12.6% expected at the end of 2011. Although GDP has risen steadily since 2002 at the rate of 7.5% in an official 2006 estimate, the state is still working to overcome a sizable trade deficit. The Economist predicted this trade deficit of 14% of Mongolias GDP would transform into a surplus in 2013. 
Question: How many percentage points higher was the growth rate for Mongolia in 2007 than in 2009? 
Answer type: Number 
Output (English): 1.
