```json { "reason": "Each cell describes multiple distinct tasks that a person performed, separated by commas or the word 'and'. The pieces are self-contained activities (e.g., 'Debugging code errors', 'generating code snippets', 'learning programming concepts') that are interchangeable in order, can appear independently in other rows, and vary in count across rows. The column name 'Tasks_Performed' (plural) reinforces that each cell holds a set of tasks. Splitting on commas yields complete, valid task descriptions that recur across rows in different combinations.", "verdict": "list", "encoding": "text_by_comma_list", "separator": null, "confidence": 0.92 } ```
