The Central Office of Information has published rejected questions for the new Citizenship Test for UK applicants. These include:
'What is the UK flag called at sea?' - This was rejected because we no longer have any ships so there is no need for any flags at sea.
'What is the price of a litre of unleaded fuel?' - Rejected because fuel in the UK is still sold by the gallon.
OK, I've made a start - over to you for more suggestions for rejected questions.
