Step 1: Understanding the Question:
This is an analogy question. We need to find the relationship between the first pair of words (Sculptor : Chisel) and apply the same relationship to the second pair (Author : ?).
Step 2: Detailed Explanation:
The relationship between a Sculptor and a Chisel is that of a professional and their primary tool. A sculptor uses a chisel to create their work.
We need to find the primary tool used by an Author.
Pen: An author uses a pen (or a modern equivalent like a keyboard) to write. This is a primary tool.
Reader: A reader is the audience or consumer of the author's work, not a tool.
Paper: Paper is the medium on which an author writes, but the pen is the tool that performs the action of writing.
Book: A book is the final product of an author's work, not a tool.
Step 3: Final Answer:
The relationship is "Professional : Tool". A sculptor uses a chisel, and an author uses a pen. Therefore, "Pen" is the correct answer.
