First of all, technology will be an effective tool to help improve our quality of life. There will be “smart homes” with high-tech appliances. People will use a phone app connected to home equipment and give orders. More houses of the future will be smaller because of the “living alone” trend.

There will be different alternative energy sources to use in houses because people care more about the environment. 31. What is the passage about? A. Future houses B. Changes in technology C.
