Evaluate the following comparative claims regarding the jurisdictional limits of the Indian and American Supreme Courts:
1. The Original Jurisdiction of the American Supreme Court is strictly confined to federal Centre-state disputes, unlike the broader Indian model.
2. The American Supreme Court lacks the constitutional authority to exercise advisory jurisdiction, a power uniquely held by the Indian Supreme Court.
3. The appellate jurisdiction of the Indian Supreme Court is strictly confined to constitutional cases, mirroring the American system.
4. The American Supreme Court possesses a massive discretionary power to grant special leave to appeal in any civil or criminal matter.
