Step 3

    From gadgets of the past, which are popular to this day, I chose the radio. Among my friends I polled. Was interesting find out their opinions.  Naturally, not one of respondents does not use an invention of our compatriot Popov every day. Almost all uses it from time to time. The answers to the second question are equally divided. Some consider the radio useful, but others find it useful sometimes. Almost all felt that radio can be improved. The fourth question was the most fun. Among those interviewed were jokers. Their answers caused me smile. The fifth question revealed that the radio will not be forgotten in future.

   The survey showed that radio is still popular, it is useful and it will not be forgotten.
