III.- Read the following passage and then choose the best answer to the
questions by circling the corresponding letter A, B, C or D.
The second half of the twentieth century saw more changes in technology than in
previous two hundred years. Penicillin has already been discovered and used to treat
infections; there have been many remarable advances in medicine that have helped to
increase our average life expectancy way beyond that of our ancestors. Incredible
innovations such as television have changed the way we spend our leisure hours. Perhaps
the most important breakthrough, however, has been the microchip. Nobody could have
imagined, when it was first invented, that within a matter of years, this tiny piece of silicon
and circuit would be found in almost every household object from the kettle to the video
recorder. And nobody could have predicted the sudden proliferation of computers that
would completely change our lives, allowing us to access information from the other side of
the world via the Internet or send massages around the world by e-mail at the touch of a
button. Meanwhile, research into other aspects of information technology is making it easier
and cheaper for us to talk to friends and relations around the world.
