Which statements about readability of health messages are true?

• A. II and III
• B. II only
• C. III only
• D. I only

Answer: (B)

Readability in health messages means the audience can understand the message easily on first reading. The most reliable guidance is to write in plain language that fits the audience’s reading level, avoid unexplained medical jargon, use short sentences and active voice, and present information in a clear, logical structure—often with headings, bullets, and helpful visuals. When a statement emphasizes tailoring language to who will read it and checking comprehension with the target audience, it directly supports real understanding and appropriate action, which is why that idea is the one that’s true. Messages that focus only on superficial aspects like length, formatting, or assuming readers will grasp technical terms without definitions don’t guarantee readability the same way plain-language, audience-centered writing does. In practice, always test materials with real readers from the intended audience to confirm they are understandable and actionable.
