In this part of the quiz, indicate the main function of the term or phrase that is in boldface in the following passage. More than one letter might be acceptable, but you must choose only one option as the best. Consider this passage by Martin Esslin: “One of the most important positive features of services under public control is their ability to provide planned, high-quality viewing alternatives. The BBC, for example, has two television channels, BBC 1 and BBC 2. The program planning on these two networks is closely coordinated so that highly popular material on one channel is regularly paired with more specialized or demanding fare on the other. And though the percentage of the audience that tunes in to the challenging programming may be small, the scale of magnitude operative in the mass media is such that even a small percentage of the viewing audience represents a very large number of people indeed .”
