Final answer:
American colonial intellectuals primarily influenced society through printed pamphlets, leveraging the period's growing print culture that connected individuals of the British Empire and fostered the exchange of enlightenment and revolutionary ideas. Therefore correct option is C
Step-by-step explanation:
Many of the American colonial intellectuals influenced society through printed pamphlets. The eighteenth century witnessed a surge in printed materials such as journals, books, pamphlets, and other publications due to the consumer revolution, linking members of the Empire and fostering a community of shared ideas. This was particularly important during periods like the Great Awakening and the Enlightenment, which promoted educational values and skepticism towards institutional authority, ultimately contributing to social change.
The flourishing print culture was integral for the Republic of Letters, a sphere where intellectuals corresponded and exchanged ideas, thereby impacting the wider society. Printed pamphlets played a crucial role in the spread of ideas and were a preferred method of communication amongst American colonial intellectuals, as they were more accessible than books and could reach a broad audience.
