I want to know the answer to the following question:
What did  Chancellor Wrighton state as one of the reasons for hosting another debate at Washington University?
All the background I'm provided with is that "Although Chancellor Wrighton had noted after the 2004 debate that it would be "improbable" that the university will host another debate and was not eager to commit to the possibility, he subsequently changed his view and the university submitted a bid for the 2008 debates.". Is that enough to answer the question?
Answer: no
