Final answer:
An exposé is a work of writing that publicizes a scandal or injustice, often associated with muckraking journalism, which differs from yellow journalism that focuses on sensationalized reporting.
Step-by-step explanation:
A work of writing that publicizes a scandal or injustice is known as an exposé. This type of writing often falls under the category of muckraking journalism, which investigates problems in government and business, and it gained prominence during the Progressive Era in the United States. Journalists known as muckrakers aimed to draw attention to societal wrongdoings and compel citizens to act for change. On the other hand, yellow journalism refers to sensationalized reporting, often sacrificing facts for more eye-catching stories. Yellow journalism seeks to provoke public emotion and engagement through exaggerated or unverified claims, as seen in the historical examples of newspaper magnates like Hearst and Pulitzer.
