In order to help the student expand his/her knowledge I will help answer the question. This in hope that the student will get a piece of knowledge that will help him/her through his/her homework or future tests.
This is true. Before we became involved in agriculture, most people were hunter-gatherers. This all changed as we started to develop more tools that helped us make work much easier and less complicated. All thanks to our imagination and curiosity.
I hope it helps, Regards.
