Explanation
The Antarctic ozone hole was reported in 1985 by Farman, Gardiner and Shanklin of the British Antarctic Survey, not 1987 (Statement I false). The original Montreal Protocol (1987) required developed countries to cut CFC consumption to 50% of 1986 levels by 1998–99 (Statement II true). Hence Statement I is false but Statement II is true.अंटार्कटिक ओज़ोन छिद्र की सूचना 1985 में ब्रिटिश अंटार्कटिक सर्वे के फार्मन, गार्डिनर और शैंकलिन ने दी थी, 1987 में नहीं (कथन I असत्य)। मूल मॉन्ट्रियल प्रोटोकॉल (1987) ने विकसित देशों से 1998–99 तक CFC उपभोग को 1986 के स्तर के 50% तक घटाने की अपेक्षा की थी (कथन II सत्य)। अतः कथन I असत्य है, लेकिन कथन II सत्य है।More People, Development and Environment questions
