Final answer:
In 'The Simpsons,' a shallow celebrity gossip story would be bumped by Kent Brockman for the Lisa Lionheart story, reflecting the transient nature of such pop culture news.
Step-by-step explanation:
The breaking news story that gets bumped by Kent Brockman's Lisa Lionheart story in the television show 'The Simpsons' is typically one that covers shallow issues such as what plastic surgeries a starlet has had. These kinds of stories, although they might be sensational and draw in viewers at the moment, are often forgotten by the next issue. They are likely written by a pop culture writer and cater to an audience that is interested in celebrity gossip and entertainment rather than hard-hitting news.
