Gutenberg perfected his printing press by 1448 and set it up in Mainz, where he printed the first book — the Bible.

The options include Strasbourg, which is a distractor — Gutenberg did spend time there earlier in his life. However, he perfected his press and established it in Mainz by 1448. Note that the given options in the question list (B) as Paris, not Mainz, which contradicts the source. Based on the source passage and historical fact, the correct answer is Mainz. If the exam lists Mainz as an option, choose it; if not, flag the error — none of the printed options (Rome, Paris, Wittenberg, Strasbourg) is correct per the textbook.
