AV and John Lewis

Its a bit like this really........ You go to John Lewis to buy a sofa. Let's assume you can't go anywhere else for the sofa. You find the sofa you'd like and order it from the assistant. She tells you that it may not be in stock and it is discontinued. She offers you a choice. If there are no more of these sofas available either you can let her choose one for you, or you can select a second choice in case you can't have the first. Which option would you take ? It's a no brainer. Obviously you would make your second choice known to her. Well, you have guessed it by now. The first option is FPTP and the second is AV. ..........There you are. http://www.hoddereducation.co.uk/Colleges/Government---Politics.aspx?mRef=CNM01.
