Wise buying is a positive way in which you can make your money go further．The   21   you go about purchasing all item or a service can actually  22  you money or can add  23    the cost．

    Take the  24  example of a hairdryer．If you are buying a hairdryer, you might   25     you are making the  26  buy if you choose one  27   look you like and which is also the cheapest  28   price．But when you get it home you may find that it  29   twice as long  as a more expensive  30   to dry your hair．The cost of the electricity plus the cost of your time could well  31  your hairdryer the most expensive one of all．

The twentieth century saw greater changes than any century before: changes for the better, changes for the worse; changes that brought a lot of benefits to human beings, changes that put man in danger. Many things caused the changes, but, in my opinion, the most important was the progress in science.

Scientific research in physics and biology has vastly broadened our views. It has given us a deeper knowledge of the structure of matter and of the universe; it has brought us a better understanding of the nature of life and of its continuous development. Technology—the application of science—has made big advances that have benefited us in nearly every part of life.

The continuation of such activities in the twenty-first century will result in even greater advantages to human beings: in pure science — a wider and deeper knowledge in all fields of learning; in applied science — a more reasonable sharing of material benefits, and better protection of the environment.

Sadly, however, there is another side to the picture. The creativity of science has been employed in doing damage to mankind. The application of science and technology to the development and production of weapons of mass destruction has created a real danger to the continued existence of the human race on this planet. We have seen this happen in the case of nuclear weapons, Although

their actual use has so far occurred only the Second World War, the number of nuclear weapons that were produced and made ready for us was so large that if the weapons had actually been used, the result could have been the ruin of the human race, as well as of many kinds of animals.
