Which Bloom's taxonomy level is demonstrated when a child explains the cause of a wart?

• A. Remember
• B. Understand
• C. Apply
• D. Analyze

Answer: (B)

Understanding is demonstrated when a child can explain why a wart occurs, not just recall that it exists. Explaining the cause requires linking the fact that warts come from a viral infection—specifically human papillomavirus—and describing how that infection leads to the skin cells growing in the way that forms a wart. This shows the child grasps the cause-and-effect relationship and can articulate how the pieces fit together. Simply naming that viruses are involved would be closer to recall; being able to explain the process reflects true understanding of why the wart develops.
