What is a major drawback of relying exclusively on books for research?

• A. They often lack detailed analysis
• B. They can be costly to acquire
• C. They may contain outdated information
• D. They are usually too lengthy to read

Answer: (C)

Relying exclusively on books for research can be problematic primarily due to the potential for outdated information. As knowledge in various fields evolves rapidly, particularly in areas such as science, technology, and social studies, books may not reflect the most current data, theories, or practices. This is especially true if the books were published years or even decades ago, meaning the insights they provide could be significantly behind contemporary understanding or developments. Utilizing a diverse range of sources, including recent articles, databases, and expert interviews, helps ensure that the information is up-to-date and relevant for the research topic at hand.
