Have finally finished with this beast, but was very confused by the preamble saying "... a quotation by one of the writers ...", instead of perhaps "...a quotation by each of the writers ...". Also, my third quote has the relevant label as the "next word but two" after the section quoted, not "the next word". This seems odd, but it has to be right?
And in case anyone is wondering how to draw the shapes, remarkably a GU10 lightbulb proved to be exactly the right size to help!
