Hi dear
How are you? Hope you are fine by the grace of Allah Almighty and I'm fine too Alhamdulillah. Life without electricity would be difficult and challenging. But if there would no electricity from onwards we would rely on traditional methods to communicate with one another through letter writing and for water we would rely on wells and rainwater. But the people of modern society cannot imagine to live without electricity as almost every work we do with the help of electricity in many factories machinery is used to do work. Best of luck for contest. Wishing you success.
