How do I hide "none" from a MC question where UNSELECTED choices were carried forwarded?

I have a single choice Q followed by a multiple choice Q where I want the UNSELECTED items from the first Q carried forward into the second Q. I want the second multiple choice Q to have a mutually exclusive "none of the above" option, however, the "none of the above" from the first single choice Q that is carried over doesn't act as a mutually exclusive option. So I need to hide it and add a "none of the above" to manage exclusivity.
I assume this is a Java script, with which I have no experience using...so please send clear instructions on how to hide an option from a carried over Q in a horizontal multiple choice Q. (Thanks ~Leslie)
