Final answer:
The printing press played a crucial role in aiding the cause of Protestant reformers by making their ideas more accessible to a wider audience.
Step-by-step explanation:
The Protestant reformers were aided by technology, particularly the printing press, in several ways. First, the printing press allowed them to mass produce and distribute their ideas at a low cost, making their message more accessible to a wider audience. Second, the translation of the Bible into various vernacular languages facilitated the spread of Protestant theology. Third, the spread of literacy and increased availability of books enabled people to engage directly with religious texts and form their interpretations.
