My error. No.9 is in Scotland, Question should have been, "How should one keep a lamp with a cord supplying fuel to its flame to burn with no excess smoke?"
This then gives a suitable (similar) answer.
8 shouldn't be impossible for a N.American as it's not a British show.
13 (US version) "Take a ride to this place, in Maine" For confirmation, vectis has PMd me with 20 correct. But I don't know vectis's geographical location.
