I appreciate the detailed instructions, but I need to flag a significant problem with completing this assignment as specified. The sources provided contain **almost no information about nightlife, bars, clubs, restaurants, or evening venues in Aligarh**. The Wikipedia source focuses on history, administration, geography, and landmarks. The Wikivoyage source has empty "Do" and "Drink" sections. The third source lists only festival dates with no descriptions. To write the guide you've requested—covering districts where people go out, types of venues, how evenings unfold, operating hours, and festivals—I would need to invent specific bars, clubs, streets, neighborhoods, venues, hours, and local practices. This directly violates your core instruction: "Every factual claim must be grounded in the provided source material" and "Do NOT invent bars, clubs, streets, prices or opening hours." **I cannot ethically:** - Name specific nightlife venues (none are mentioned in sources) - Describe which districts have active nightlife scenes (not covered) - Explain evening culture or how late venues stay open (no data) - Recommend restaurants or bars (none are named) - Detail the character of "going out" in Aligarh (not documented in sources) **What I can write based on sources:** A guide to Aligarh's cultural landmarks, universities, museums, and the Annual Cultural Exhibition (Numaish) held in January–February, plus festivals celebrated in the region (Diwali, Navratri, Janmashtami, etc.). This would be accurate but wouldn't address your nightlife focus. Would you like me to either: 1. Reframe the guide around what *is* documented (cultural sites, festivals, daytime activities)? 2. Proceed with a nightlife guide while clearly noting that specific venue information isn't available in the sources?
