I want to know the answer to the following question:
What university awarded Lee an honorary doctorate in 2006?
All the background I'm provided with is that "During the ceremony, the students and audience gave Lee a standing ovation, and the entire graduating class held up copies of To Kill a Mockingbird to honor her.[note 5] Lee was awarded the Presidential Medal of Freedom on November 5, 2007 by President George W. Bush.". Is that enough to answer the question?
