In the given analogy question, we need to find a pair of words that have a similar logical relationship to "surgery" and "writer." The original sentence is:
"\underline{\hspace{1cm}} is to surgery as writer is to \underline{\hspace{1cm}}"
Let's analyze the structure and intended relationship:
-
Understand the role: A person responsible for surgery is typically a doctor. Similarly, the person responsible for writing is a writer. Therefore, the correct sequence should be "Doctor is to surgery as writer is to book."
-
Matching the analogy:
- Doctor: The main professional associated with surgery.
- Book: The main product created by a writer.
Thus, the logical relationship matches correctly with the option "Doctor, book."
Now let's examine each of the options to determine why the others are incorrect:
- Plan, outline: While a plan is related to an outline, this does not maintain a similar analogy to the original sentence, as planning is not directly associated with surgery or writing.
- Hospital, library: This pair relates two professions to locations, and while both are places, they do not maintain the "doer-action-product" relationship of the original analogy.
- Medicine, grammar: These items are part of systems within their fields (medical treatment and language, respectively) but do not align with the doer-product analogy.
Conclusion: The correct option is "Doctor, book" because it accurately follows the relationship pattern: a doctor performs surgery, and a writer writes books.
