Radio isn’t out of date, and a lot of people listen to it every day. Marconi, the Italian【66】______who gave us the radio, probably didn’t realize what【67】______ his great invention would have on the world in years to come. Radio has, perhaps, had as much influence on the world as any other【68】______device. Events of universal interest can be reported to the entire globe a few second after they happen,【69】______in remote areas, ships at sea, even astronauts【70】______ the earth are able to keep in touch with civilization by means of radio.
