Passage 3
Though many television programs are very trivial, all channels have many admirable features, which make the best 1 use of this new 2 and wonderful entertainment and information, not to mention intellectual 3 . More than anything else, television drama_4 special mention. It may be difficult to go to a theater, but people who stay at home have5 opportunity for seeing good plus6 produced for television, as well as good programs of criticism. The remarkable growth in the circulation of the good-quality Sunday newspapers, and the7 of some of their less admirable rivals, indicates an improvement of the public taste, and although the development of education may have something to do with this it seems likely that television is 8 responsible too.

There seems to be enough evidence to suggest that a great restraint over a long period in such portrayals 20 a worthwhile experiment.
