A verbal agreement (or oral agreement) is spoken.
Knots usually take 1 minute or so to do. If you keep on tying the knots and get used to the pattern, you will get faster and faster and eventually will be able to do it in 4 seconds. It is kind of like picking strawberries. If you keep on picking strawberries and timing yourself, you will get faster like when you typed the knot
The answer (after 2 hours of deciphering...) is
"THE TONGUE IS THE ONLY INSTRUMENT THAT GETS SHARPER"
Hope I could help, this was a tough one.
I would say electricity. It keeps everything going all around the world. I really dont care about my phone but I cant lose light! #Books
