A "tool" is defined as "an instrument or device that is held by the hands and used to perform a particular task or function." Think about the tools you have used so far today. What is the most primitive tool you have used today and why? What is the most advanced tool you have used and why? *

Hammer is the most primitive tool I have used today. I have to say it is the most primitive tool because hammer has been around since stone ages. And these days more effective and faster tool has been created to replace the hammer. That leads me to the second answer. Nail gun is the most advanced tool I used. Its the most advanced tool because it need technology to make the better version of a hammer. Also, it can make work a lot easier and faster.

what are the options? add them, then i will be glad to .
