Step-by-step explanation:
All of the following are ways that Johannes Gutenberg's printing press improved society EXCEPT: d. It caused Europeans to only focus on religious books and texts.
Johannes Gutenberg's invention of the printing press was a pivotal moment in European history. One of its most notable impacts was the mass production of literature, which it made much faster and more affordable (mass produce literature). This revolutionized communication and enabled better organization among people, facilitating a dramatic improvement in the capacity for the spread of ideas.
The accessibility of printed material also significantly increased literacy rates across Europe, as books became more widely available to different classes of society, not just the wealthy or the clergy.
However, Gutenberg's press did not lead Europeans to focus solely on religious texts. Although the first major work he printed was indeed the Bible, the press soon diversified the types of literature it produced. It had a broad impact, disseminating not only religious but also secular texts, contributing to the spread of Renaissance humanism and the scientific advancements of the time.
