Explanation

{"question_number": 8, "question": "What is a comparison of YAML and JSON?", "correct_answer": "B", "explanation": "The key factual difference highlighted in Answer B is correct: JSON does not support comments in its specification, while YAML does support comments using the '#' character. This makes YAML more suitable for configuration files where inline documentation is valuable. Answer A is incorrect - YAML's multiple ways to represent the same data (block style, flow style, anchors, aliases) make it less consistent, not more, compared to JSON's strict syntax. Answer C is incorrect - YAML is generally less verbose than JSON because it does not require quotes around strings or curly braces/brackets for structure. Answer D is incorrect - YAML is actually more commonly used in configuration management tools (Ansible playbooks, Kubernetes manifests, Docker Compose), while JSON is more prevalent in REST APIs.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
