result of thousands of years of human invention.
First, came the invention of
writing, {#blank#}1{#/blank#}(probable) .about 5, 500 years ago. With writing, people did not
have to remember everything in their heads. They could communicate with people
that they never{#blank#}2{#/blank#} (see) and share their knowledge with insure generations.

pages of books were made from animal skin. That changed in {#blank#}5{#/blank#}thirteenth
