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 "A number of the city's downtown employers are relatively new, as there has been a marked trend of companies moving from satellite suburbs around Metropolitan Detroit into the downtown core.[citation needed] Compuware completed its world headquarters in downtown in 2003. OnStar, Blue Cross Blue Shield, and HP Enterprise Services are located at the Renaissance Center. PricewaterhouseCoopers Plaza offices are adjacent to Ford Field, and Ernst & Young completed its office building at One Kennedy Square in 2006. Perhaps most prominently, in 2010, Quicken Loans, one of the largest mortgage lenders, relocated its world headquarters and 4,000 employees to downtown Detroit, consolidating its suburban offices. In July 2012, the U.S. Patent and Trademark Office opened its Elijah J. McCoy Satellite Office in the Rivertown/Warehouse District as its first location outside Washington, D.C.'s metropolitan area."?
The answer to this question is:
What was the US Patent and Trademark Office and Elijah J. McCoy Satellite Office in the Warehouse District also known as?
