    "reasoning": "The user is asking for 3 interesting analytical questions this dataset could answer. I have comprehensive evidence about the Titanic dataset:\n\n1. From step-0 (overview): This is the RMS Titanic disaster dataset with 891 passenger records, containing demographics, ticketing, cabin assignments, and survival outcomes.\n\n2. From step-1 (gold tables): 15 pre-aggregated tables exist, grouped by various combinations of Cabin, Parch, Pclass, Sex, and Survived.\n\n3. From step-2 (column inspection): Key dimensions include Sex (2 values), Pclass (3 values), Survived (2 values), Age (measure with 177 nulls), Fare (measure), Embarked (3 ports), Cabin (163 distinct, 687 nulls), Parch (parents/children aboard), SibSp (siblings/spouses).\n\n4. From step-3 (survival by class): Already shows survival rates vary dramatically by passenger class - first class had higher survival (136 survived vs 80 died) while third class had much lower survival (119 survived vs 372 died).\n\nI have sufficient evidence to propose 3 compelling analytical questions without needing additional queries. The dataset naturally supports questions about:\n- Survival determinants (class, sex, age, family structure)\n- Fare economics and class stratification\n- Demographic patterns and family traveling behaviors\n\nI should craft questions that are specific, analytically rich, and grounded in what the data actually contains."
