I filled out the questionnaire myself (I posted it here). While doing so, I thought some questions may be interpreted differently from how you did.

I think question 6 is about another potential gas cutoff by Russia, and possibly the fears of Poland and the Baltics, not Britain. Britain has a long-term, not a "shorter-term emergency" problem.

Regarding question 9, now I might not know well the nuances of the English language, but to me it reads as if "balance between" means how much weight one wants to give each, which in my mind includes giving one a value of zero. Regarding demand reduction, I think it does appear with a different wording in question 7.
