Answer:
The right answer is: "By making it easier to publish and spread ideas."
Step-by-step explanation:
Johannes Gutenberg invented the printing press just a few decades before the start of the Protestant Reformation by Martin Luther in 1517. Its impact was truly revolutionary. The existence of that machine allowed to spread the Protestant ideas throughout Germany and Europe and get the message delivered to the masses; it would definitely have been much more difficult to take the message of Reformation to all corners of Europe by using the traditional methods.
