I want to know the answer to the following question:
What was the shipping services imported by Greece in 2011 worth?
All the background I'm provided with is that "Counting shipping as quasi-exports and in terms of monetary value, Greece ranked 4th globally in 2011 having "exported" shipping services worth 17,704.132 million $; only Denmark, Germany and South Korea ranked higher during that year.". Is that enough to answer the question?
