What short, humorous story breaks up or lightens serious or somber news?

The term that best describes a short, humorous story used to break up or lighten serious or somber news is "bright." In journalism, a bright is typically a light-hearted piece that contrasts with more serious coverage, providing a moment of levity. It serves to engage the audience and can help to maintain interest amid heavier news content.

This technique is often utilized to balance the emotional tone of news programming, making it more accessible by offering a bit of enjoyment or amusement. By doing so, it enhances the overall viewer experience, allowing the audience to digest serious topics with a break for humor.

The other options represent different functions in journalism. A feature is a more in-depth, often human-interest story that explores a topic in detail but is not necessarily humorous. A news break refers to a short update or interruption of regular programming with news, which may not include humor. An editorial expresses a specific opinion on an issue and is generally more serious in nature, focusing more on argumentation than lighter content. Thus, the bright stands out as the correct choice for a humorous story that lightens the mood.
