It was sometime in 2004. It was prior to the June meetings because my husband was a teacher at the school, so I often heard things that he would come home and tell me. So I knew that there was some discussion over the biology book, so sometime before that. I can't tell you exactly when.
In 2003, the biology book was published.
We do not know when the biology book was published so the statement is neither definitely correct nor definitely incorrect.
