Who among the following composers won the Grammy in 2015 for his album 'Winds of Samsara' – a collaboration with South African flautist Wouter Kellerman?

The correct answer is C, 1972. The Convention Concerning the Protection of the World Cultural and Natural Heritage was adopted by the General Conference of UNESCO in 1972, and countries that join it nominate sites of outstanding universal value, which a committee then inscribes on the World Heritage List as cultural, natural or mixed sites. Option A is wrong because 1946 is the year the UNESCO Constitution came into force. Option B is wrong because 1954 is the year of the Hague Convention on protecting cultural property during armed conflict, a related but different treaty. Option D is wrong because 2003 is the year of the Convention for the Safeguarding of the Intangible Cultural Heritage, which covers living traditions such as dance, music and craft rather than monuments and natural sites.

The correct answer is A, International Literacy Day, 8 September. UNESCO presents the King Sejong Literacy Prize and the Confucius Prize for Literacy every year on 8 September, the day it observes as International Literacy Day, and the prizes reward governments, organisations and individuals whose programmes have spread reading and writing. Option B is wrong because 3 May, World Press Freedom Day, is the date of the Guillermo Cano World Press Freedom Prize. Option C is wrong because 16 November, the International Day for Tolerance, is when the Madanjeet Singh Prize is presented; the same date is also the anniversary of the signing of the UNESCO Constitution. Option D is wrong because 10 December, Human Rights Day, is the date of the United Nations human rights prize, given once in five years.

The correct answer is A, the United Nations High Commissioner for Refugees. The award has been given since 1954 by the refugee agency of the United Nations to a person, group or organisation that has served refugees, displaced people or those without a state. It is named after Fridtjof Nansen, the Norwegian explorer and scientist who became the first High Commissioner for Refugees under the League of Nations and won the Nobel Peace Prize in 1922. Option B is wrong because the Development Programme publishes the Human Development Report rather than this award. Option C is wrong because UNICEF works for children and gives the Maurice Pate Award. Option D is wrong because the International Labour Organization, based at Geneva, deals with working conditions and labour standards.

The correct answer is C, Indira Gandhi. The United Nations Population Award was instituted by the General Assembly in 1981 and first presented in 1983, when Indira Gandhi of India was one of the two individual laureates, honoured for India's early work on population policy. The Indian industrialist J R D Tata received the same award in 1992. Option A is wrong because Jawaharlal Nehru died in 1964, long before the award existed. Option B is wrong because Lal Bahadur Shastri, Prime Minister from 1964 to 1966, also died before the award was created. Option D is wrong because Morarji Desai, Prime Minister from 1977 to 1979, is remembered for receiving Pakistan's highest civilian honour, the Nishan-e-Pakistan, rather than this award. Keep the two Indian names of this award together, Indira Gandhi in 1983 and J R D Tata in 1992, because a paper may ask for either.

The correct answer is B, the United Nations Environment Programme. Champions of the Earth was launched in 2005 by the United Nations Environment Programme, whose headquarters are at Nairobi in Kenya, and it recognises leaders from government, civil society and business whose work protects the environment, in categories such as policy leadership, entrepreneurial vision and science and innovation. Option A is wrong because UNESCO's work on nature runs through biosphere reserves and natural World Heritage Sites rather than this award. Option C is wrong because the World Health Organization, based at Geneva, gives awards in public health. Option D is wrong because the Food and Agriculture Organization, based at Rome, works on food security and hunger. A related honour for young people is the Young Champions of the Earth award.
