Something To Do
1. What would have been the life of human beings without fire, wheel and iron?​

Answer 1

Answer:

Well, the simplest answer is "life would be difficult".

Now-a-day, Fire, wood, and iron are the important things for human beings. Life would have been a lot more difficult without these things.  

Without fire, I could only have relied on sunlight as a light source. Also, there would be no food cooking source. 

Without the wheel, there would be no car, motorcycle or bicycle and humans would be restricted to dragging or rolling large things.

Similarly, iron is the most important metal in today's world. So, without iron we could only be restricted to bronze or other metal made things.
