yellow journalism reports featured accurate information from reliable sources.

Explanation:

Yellow journalism was a form of sensationalist reporting. In the late 19th century, newspapers were a primary source of information for the public. When newspapers used yellow - journalism tactics (exaggeration, false stories, etc.) about events in Cuba (pre - Spanish - American War), since people got most of their information about world events from newspapers, it had a strong impact on public opinion.
