Consider the following pairs: International Agreement /set-up - Subject 1) Alma-Ata Declaration - Healthcare of The people 2) Haugue Convention - Biological and chemical weapons 3) Talanoa Dialogue - Global climate change 4) Under2 Coalition - Child rights Which of the pairs given above is/are correctly matched?

Alma-Ata Declaration (1978), adopted at the International Conference on Primary Health Care, is the foundation of the primary healthcare approach, so pair 1 is correct. Talanoa Dialogue was launched under the UNFCCC during Fiji's presidency of COP23 (2017) to take stock of climate action toward the Paris goals, so pair 3 is correct.

Pair 2 is wrong. The Hague Conventions (1899 and 1907) deal with the laws and customs of war. The ban on biological and chemical weapons comes from the Biological Weapons Convention (1972) and the Chemical Weapons Convention (1993).

Pair 4 is wrong. Under2 Coalition is a group of subnational governments committed to limiting warming to 2 degrees Celsius. It has nothing to do with child rights.

• Core concept: international environmental and health governance. Know which body or treaty belongs to which subject.

Mains angle: the Alma-Ata idea still shapes India's health policy, including Ayushman Bharat's health and wellness centres.

Trap: Assuming every 'Hague' treaty concerns arms control, or mixing up the Hague Conventions on war with the 1970 Hague anti-hijacking convention.
