Hide/Unhide Rows based on column data using checkbox

I have a questionnaire that I am developing that will require additional questions based on the group. There are standard questions that are visible when questionnaire is opened. I want to use check box to add additional questions for that that group (Group A). I want to use a check box for to add questions and hide some of the standard questions for that group (Group B).

I have read some of the threads and did not see a solution to my specific need.

I need to insure that macros hide or unhide the right rows when I need to add additional question rows.

Attached file is a test example. The actual questionnaire will have over 200 lines and over 20 possible groups or scenarios.

Thank you for any assistance that can be provided.
