Answer:
The correct answer is A. As a result of Gutemberg's invention of the printing press, books became less expensive and more available throughout Europe.
Step-by-step explanation:
Johannes Gutenberg created a manual printing press in the mid-1440s. It is believed that the basis of his invention formed similar mechanisms of a wine press and a paper-making press. Gutenberg's inventions very soon spread throughout Europe, and then around the world.
The printing press became one of the key factors that accelerated the onset of the Renaissance, as it allowed a greater diffusion of knowledge by reducing both costs and printing times of books. In addition, it took away the monopoly of the distribution of knowledge from the monks, thereby secularizing scientific knowledge.
