A、Human lives become worse than ever before. B、Human lives become better than ever before. C、Human lives have no change at all.

The twentieth century has brought with it many advances. With those advances, human lives have changed dramatically. In some ways life is worse, but mostly it is better. Changes in food preparation methods, for example, have improved our lives greatly.
   Food preparation today allows for more variety. With refrigerators and freezers, we can preserve a lot of different foods in our homes.Since technology makes cooking so much faster, people are willing to make several dishes for even a small meal. Parents are more likely to let children be picky, now that they can easily heat them up some prepackaged cakes and cheese on the side. Needless to say, adults living in the same house may have very different eating habits as well. If they don’t want to cook a lot of different dishes, it’s common now to eat out at restaurants several times a week.
   Healthful eating is also easier than ever now. When people cook, they use new fat substitutes and cooking sprays to cut fat and calories. This reduces the risk of heart disease and other diseases. Additionally, we can buy fruits and vegetable fresh, frozen or canned. They are easy to prepare, so many of us eat more of those nutritious items daily. Our lifestyle is fast, but people still like good food. What new food preparation technology has given us is more choices. Today, we can prepare food that is more convenient, healthier, and of greater variety than ever before in history.
