Final answer:
The earliest printing presses were indeed run by monasteries. Johannes Gutenberg's invention of the movable-type printing press revolutionized book production.
Step-by-step explanation:
The statement is true: The earliest printing presses were indeed run by monasteries. In the 11th century, monasteries became repositories of information, and illuminated manuscripts became a viable industry. Monks wrote and illustrated biblical information, as well as copied classical philosophers. However, the invention of the printing press changed everything. Johannes Gutenberg, a German entrepreneur, independently invented movable-type printing in the 15th century. His printing press revolutionized book production and led to the spread of printing technology across Europe.
