Question
Which of the following is NOT a reference material?
Correct Answer
Option D is the correct answer.
Detailed Explanation
Dictionaries, encyclopedias, and indexes are all examples of reference materials designed for quick consultation of specific facts. Journals are periodicals containing articles on original research and are not typically considered 'reference' materials in the same way.
Hint
Think of materials you go to for a quick fact, not to read cover-to-cover.
