In the first place, television is not only a convenient source of entertainment, but also    3         comparatively cheap one. For a family of four, for example, it is   4            as well as cheaper to sit comfortably at home, with almost unlimited entertainment available, than to go out in search of amusement elsewhere.
All they have to do is    5          (press) a button, and they can see plays, films, operas, and shows of every kind, not to mention the latest   6        (excite) football match. Some people,    7            maintain that this is precisely     8           the danger lies. The television viewer makes no choice and exercises no judgment. He is completely passive and has everything   9          (present) to  10           without any effort on his part.
