This can be used as an engine all you have to do to make a new quiz is to reset the cloud variables, Change items in the list ('List of countries' not 'List') and change the backdrops and their name.
I learnt how to use cloud variables and coding decoding part from @Griffpatch 's YouTube tutorial. This time the Score system has a huge overhaul New Flags are also added and some old ones removed. (and one replaced ?)
