The invention of the bicycle мейд it (a lot/easier) for people to travel from one village to another, to meet new people. The world has become a much safer  place to live since the invention of antibiotics. People are (by far/healthier) now than 100 years ago. The invention of the washing machine has meant that it is (a lot/quicker) for people to wash their clothes. I think it's (the best) invention of the last century. Although we have computers, paper is still the (cheapest) and (most flexible) way to record the written word. Electricity is the (most important) invention because without it many of the other things we have would not have been possible. The invention of the telephone and the computer have meant that we (are much/busier) now than we were in the past.
