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 ""These one-of-a-kind events are great experiences for our students, they contribute to a national understanding of important issues, and they allow us to help bring national and international attention to the St. Louis region as one of America's great metropolitan areas," said Wrighton.". Is that enough to answer the question?
Answer: yes
