Questions: During the mid-1770s, political dissent was stimulated by the printing and circulation of short books called pamphlets, pulp novels, paperbacks, POD books

The answer is pamphlets.

Pamphlets were widely used during the mid-1770s as a means of spreading political ideas and dissent. They were short, inexpensive, and easy to distribute, making them an effective tool for influencing public opinion and rallying support for causes such as the American Revolution.

Pulp novels are a type of literature that became popular in the late 19th and early 20th centuries, characterized by their sensational and often low-quality content. They were not relevant to the political dissent of the mid-1770s.

Paperbacks are a format of book that became popular in the 20th century, known for their affordability and portability. They were not a factor in the political dissent of the mid-1770s.

Print-on-demand (POD) books are a modern publishing technology that allows books to be printed as needed, rather than in large print runs. This technology did not exist in the 1770s and therefore was not relevant to the political dissent of that time.
