Final answer:
To help readers understand the central idea of humor in the brain, text features like punny titles, images of comedians, and diagrams of brain processes play crucial roles.
Explanation:
A title that includes a pun to indirectly introduce the topic would be the most effective text feature to help readers understand the central idea of the brain's role in humor. Puns are humorous wordplays that can grab readers' attention and hint at the lighthearted nature of the content.
An image of a comedienne performing a stand-up routine could also be a useful text feature to visually showcase the practical application of humor and its connection to the brain.
A diagram of the way the pre-frontal cortex processes humor would be instrumental in providing a clear visual representation of the brain's involvement in processing humor, offering a deeper understanding to readers.
