863211 and Pjiang: Please Help on the Membership of communist pa

I had I-485 back to 2005 as a dependent, and I withdrew it in 2008 when devorced while it was still pending. I can not remember it was YES or No chosen for this membership question . I file my I-485 couple of days ago, and chose No to this question. What is the consequence if in case it was YES chosen before so it is inconsistent.

Thanks a lot!
