The document is a reading comprehension test with multiple choice questions about a passage. The passage discusses how radio is used on large farms in Australia due to their isolation. It describes how the government set up a two-way radio program so farmers could contact doctors for medical advice. It also discusses radio schools being set up for farm children who could not attend regular schools due to the distance. Farm families would use "round robin" radio talks to keep in touch and share news. The radio became an important communication tool and source of information for isolated farm communities in Australia.
