Explanation

{"question_number": 10, "question": "Which of the following is the best reason for cleansing the data?", "correct_answer": "A. Duplicate data", "explanation": "Duplicate data - records that appear more than once in a dataset - is one of the most common and impactful reasons to cleanse data, as duplicates skew analysis results, inflate counts, and compromise data integrity. Imputed data refers to values filled in to replace missing data, which is itself a cleansing technique rather than a reason to cleanse. Redundant data is similar to duplicate but typically refers to unnecessary repeated fields. Corrupt data is a valid cleansing reason, but duplicate records are the most frequently cited data quality issue requiring cleansing.", "generated_by": "claude-sonnet", "llm_judge_score": 3}
