Excess verbiage Dept.: every word of this question, up to and including SWALK (I make that 22 words) is completely irrelevant. I don't know what the significance of the number is, but the question could simply have read "Which town or county is indicated by a postcode beginning 'NN'?"
Ten words, instead of 42.
The same comment (with the numbers changed) would apply equally to the subsequent question.
And for the question after that: "Which country has the ISO code CIV?" - seven words, instead of thirty.
