Final answer:
A headline should state either an accepted fact, a recent event, or a claim that is proven in the body of the story.
Step-by-step explanation:
Raj explains to his journalism students that, as a general rule of thumb, a headline should state one of three things. The three things he most likely means are:
- An accepted fact: A headline could state something that is widely known and accepted to be true.
- A recent event: A headline could inform readers about a recent occurrence or development.
- A claim that is proven in the body of the story: A headline may present a bold claim, which is backed up and supported by evidence in the body of the article.
