I want to know the answer to the following question:
According to The American Library Association, what rank did the book have among the most frequently challenged books from 2000 to 2009?
All the background I'm provided with is that "The American Library Association reported that To Kill a Mockingbird was number 21 of the 100 most frequently challenged books of 2000–2009.". Is that enough to answer the question?
Answer: yes
