Which word means "the topic or subject discussed in a book, essay, etc."?

• A. Theory
• B. Text
• C. Tentative
• D. Theme

Answer: (D)

The central idea a book or essay conveys is its theme. This goes beyond just naming the subject being discussed; it’s the underlying message or insight the author wants to communicate about that subject. For instance, if a story centers on friendship, the theme might be that loyalty and trust prove their value when times get tough. This distinction helps: the topic or subject could be friendship, while the theme is what the author says about that topic—like loyalty enduring under pressure. Other options don’t fit because they refer to different ideas: a theory is a system of ideas about how something works, the text is the actual written material, and tentative means not certain. So the correct term here is theme.
