Which noun means something that takes the place of another?

Which noun means something that takes the place of another?

• A. Replacement
• B. Extension
• C. Conversion
• D. Transformation

Answer: (A)

Substitution is what this question tests: finding a noun that means something that takes the place of another. Replacement fits best because it directly means something that stands in for or substitutes for something else. For example, a replacement part can take the place of a broken one. The other options describe different ideas: extension is about adding length or amount, conversion is changing from one form to another, and transformation implies a broad, often complete change in form or nature.
