Read the following passage. Decide if the statements from 13 to 16 are True or False, and choose the correct answers (A, B, C or D) for questions 17 and 18

There is a list of interesting jobs that we’ll never have again, and a town crier is, of course, on the list. It’s been a long time since town criers worked professionally, so there are not many people knowing who town criers were. Today we can only see them in the movies or at some old tourist sites. Before newspapers were invented, a town crier, who was usually an older gentleman with a booming voice, always dressed offically and had a little bell which he carried with him always. His job was to go through city streets ringing the belt and shouting the latest news as he was walking.

The occupation of the town crier was quickly replaced by radio, television, texting, internet, and all the marvels of modern technology. Today this occupation exists only for entertaining purposes and as local folklore. Competitions for the best town criers are still being held in some parts of the world like America, Australia, Canada and England.

Town criers had worked professionally before mass media were invented.
