The invention of papyrus significantly changed life for ancient Egyptians primarily because writings could be moved and stored more easily. Papyrus, a lightweight and flexible writing material made from the papyrus plant, allowed for the documentation of various aspects of life, including administrative records, religious texts, literature, and communication. This ease of writing and portability facilitated record-keeping, governance, and the sharing of information across distances, contributing to the advancement of Egyptian civilization.
While papyrus did have some durability advantages and was sourced locally, the key impact was its role in enhancing communication and administration. The option regarding a new class of soldiers is not related to papyrus and is incorrect in this context.
