I want to know the answer to the following question:
In what year were twice as many glacial earthquakes seen than in any other year in Greenland?
All the background I'm provided with is that "In a study using data from January 1993 through October 2005, more events were detected every year since 2002, and twice as many events were recorded in 2005 as there were in any other year.". Is that enough to answer the question?
