You can discuss with your group and give at least 2 reasons. It’s important for several reasons. First, books became easier to make and knowledge spread faster. Before printing, people copied books by hand. It took a long time. Printing let people make many books quickly. With more books, ideas traveled far and wide. Second, mistakes happened less.
