Which best describes printing before the invention of the Gutenberg printing press?

a) a long, expensive process.

Before the printing press was invented, writings were produced by hand. Generally, the ones in charge of producing these texts were the scribes, the professional copyists who lived in monasteries. Moreover, it used to take the scribes several months to complete their jobs.  

Different expensive materials, such as papyrus, clay, wax, and parchment, were used to transcribe law books, tragedies, and works related to philosophy.

Gutenberg's invention allowed more people to access knowledge since the printing press became a less costly and faster method to reproduce texts.
