Which source would you consult for a quick overview and definitions of a topic?

• A. Textbook
• B. Encyclopedia
• C. Primary source
• D. Research article

Answer: (B)

When you need a quick overview and definitions, an encyclopedia is the best fit. Encyclopedia entries are written to give concise, accessible summaries of topics and clearly define key terms, often with brief context and cross-references to related concepts. This makes them ideal for getting oriented fast. In contrast, a textbook tends to offer a deeper, structured treatment designed for learning in a course; a primary source provides original evidence or artifacts rather than a summary; and a research article delivers detailed, specialized findings rather than broad overviews. Start with an encyclopedia for a fast grounding, then move to other sources if you need more depth.
