Read this passage carefully, then choose the correct answers

III. Read this passage carefully, then choose the correct answers. Technology will allow homes in the future to be “smart.” Appliances will communicate with each other - and with you. Your stove, for example, will tell you when your food is cooked and ready to eat. Refrigerators will suggest recipes based on food items you already have. Futurologists predict that many homes will have robots in the future. Robots already do many things such as building cars and vacuuming floors. But scientists today are starting to build friendlier, more intelligent robots that will be able to show feelings with their faces, just like humans. These robots will do work around the house such as cooking and cleaning. They will even take care of children and the elderly. How soon will this smart home be a reality? There’s a good chance it will be a part of your life in 25 or 30 years, perhaps sooner.
