Good to know, headings are really toughso headings are same!
i also marked 20 years one.
i chose urban and rural and when there were only two mins left i erased it and marked option A(negatives more than positives)
For "between urban and rural" - it was written in the text that those birds would prefer to be in the wild in the summertime and to move to gardens in winters, so I'm almost sure.
