I want to know the answer to the following question:
How many copies of Late Registration were sold in the United States?
All the background I'm provided with is that "Late Registration sold over 2.3 million units in the United States alone by the end of 2005 and was considered by industry observers as the only successful major album release of the fall season, which had been plagued by steadily declining CD sales.". Is that enough to answer the question?
