As an example I'll use one of my own questions but there is no need to read more than its title to understand my question here.
It looks as though the answer is going to be No. However someone has mentioned an apparent flaw in my plan that I believe I can exploit to make my scenario work.
When writing my new question, I will obviously state the new factor and say how it might overcome previous objections.
How much of the original should I restate?
(a) None - just give the link back to my old question and add the new factor (stating why it helps).
(b) Summarise the old question in bullet form and add the new factor.
(c) Repeat the old question word-for-word and add the new factor to the list.
(c) Something else.
To make it more concrete: In my particular case the original idea was that the balloon should self-stabilise equidistant from the planet's surface. An objection was that the solar wind would displace it. I now want to know if I can utilise the solar wind as a stabilising factor - perhaps by having it pin the balloon to the surface on one side rather than be equidistant. (Details still fuzzy)
