Final answer:
The Gutenberg printing press revolutionized book production and knowledge dissemination in the early modern period.
Step-by-step explanation:
The technological advancement during the early modern period that revolutionized book production and facilitated the spread of knowledge was a) The printing press. Invented in the mid-fifteenth century by Johannes Gutenberg, the Gutenberg printing press significantly improved upon earlier Chinese and Korean printing methods. Gutenberg's innovation was the use of moveable type which was more efficient for languages based on alphabets rather than characters.
The production of the Gutenberg Bible around 1455, with 180 identical copies, marked the start of a new era in book production. Knowledge could be disseminated more widely and at a faster rate than ever before. This printed material helped to fuel the Renaissance, aiding the spread of Humanism, and played a part in the Reformation led by figures such as Martin Luther. The printing press's influence on literacy, education, and the sharing of ideas was profound, seeding the modern age of information and learning.
