Read the given passage and answer the following questions  - 

The Gutenberg Bible, printed by Johann Gutenberg in Mainz, Germany, around 1455, stands as a monumental achievement in the history of publishing and marks the start of the age of the printed book in the West. This iconic work, also known as the 42-line Bible, was the first major book printed using mass-produced movable metal type, revolutionizing the process of book production, and making literature more accessible to a broader public.

Before the introduction of movable type, books were painstakingly copied by hand, usually by members of religious orders. This labor-intensive process made books rare, expensive, and primarily confined to wealthy individuals and institutions. Gutenberg's invention dramatically changed this landscape, allowing for the faster production of books and significantly reducing their cost. This had profound cultural and social implications, leading to increased literacy rates, the spread of knowledge, and the democratization of learning.

The Gutenberg Bible itself is an example of exquisite craftsmanship. Each of its volumes was produced with great care, featuring high-quality paper or vellum, precise and clear type, and beautifully illuminated initials added by hand. Despite the uniformity allowed by movable type, each Gutenberg Bible shows unique characteristics due to this hand-finishing process.

Today, of the estimated 180 copies originally produced, only 49 are known to survive, and they are among the most valuable books in the world. These copies are held in libraries and collections around the globe, cherished not only for their historical significance but also for their beauty and artistry.

The legacy of the Gutenberg Bible and its impact on the dissemination of knowledge cannot be overstated. It laid the groundwork for the Reformation, the Renaissance, and the Scientific Revolution, influencing virtually every aspect of modern society. It serves as a testament to human ingenuity and the enduring power of the printed word.
