This Quiz has no particular theme unfortunately: No. 1. What B is mainly on a wall or around a mathematical equation. No. 2. Or you might prefer 11 and 9 are this. Because this clue uses the word "or" I wonder if it refers in any way to the previous answer - which is Black Magic. Presumably the 11 and 9 refer to the answers for Question No.s 11 and 9 which are: Banbury Cross and Coventry. Number of letters to the answers are not given. Anyone out there any brainwaves? Wold appreciate any help.
