Main Idea Practice Test

The invention of the printing press in the 15th century revolutionized the way information was shared and preserved. Before this innovation, books were painstakingly copied by hand, making them expensive and rare. Johannes Gutenberg's movable type system allowed for mass production of books, dramatically reducing costs and increasing accessibility. This technological breakthrough not only made literature and knowledge more widely available but also accelerated the spread of ideas, contributing to major cultural and intellectual movements like the Renaissance and the Reformation.
