If John uses the word "deleterious" while speaking to senior citizens, what is the likely outcome?

• A. They would fully understand its meaning
• B. They may not comprehend the term
• C. It would enhance his credibility
• D. They would find it humorous

Answer: (B)

Using a term like "deleterious," which means harmful or damaging, can be challenging for an audience that may not be familiar with more complex vocabulary. When speaking to senior citizens, it's possible that they may not encounter such specialized or less commonly used words regularly, which could affect their understanding. This does not imply that they lack intelligence or comprehension skills, but rather that the specific term could impede immediate understanding, leading to possible confusion.

In contrast, the other outcomes focus on different interactions that are less probable in this context. While using complex vocabulary might enhance credibility for some audiences, it generally relies on context and shared knowledge. Given an audience that may appreciate clarity and simplicity in communication, using less complex language is often more effective for ensuring comprehension.
