Translation:Is there a charge for the plastic bag for life?
A bag for life is offered by some supermarkets in the UK for a small charge. This can be reused and they will also replace it, free of charge, when necessary, hence the term 'bag for life'. The supermarket will often have a selection of reusable bags for sale. They will not all be bags for life.
Ok, it's a pity you can't see the notes on the mobile before doing the exercise. I first had "is there a charge for the plastic bag for life", but it sounded so wierd that I changed it to "is there a charge for life for the plastic bag" (i.e. will you get imprisoned for life for using the plastic bag) and was marked wrong... :-)
