Read the paragraph and answer the questions. In some countries advertising is controlled. For example, in Britain there are rules called a `Code of Advertising Practice`. The code contains the standards for advertisements. It guides companies about what they can claim in their adverts. it is also the standard for evaluating adverts. Adverts must be honest, fair and decent. So, for example, if an advert claims that a car is the fastest in the world, the company must be able to show that this is true. How do you think? Why should countries control advertising?
