Explanation
- A
an agency of the United Nations to help refugees of civil wars
Helping refugees of civil wars is the work of UNHCR and related UN bodies, not Amnesty International. Amnesty is not a United Nations agency. This option is therefore not the key.
- B
a global Human Rights Movement
Amnesty International is a worldwide non-governmental movement that campaigns for human rights: prisoners of conscience, torture, death penalty, unfair trials and related abuses. That description matches the organisation. This option is the official key.
- C
a non-governmental voluntary organization to help very poor people
Poverty relief is the field of development NGOs and charities; Amnesty’s mandate is human rights research and campaigning, not general anti-poverty work. This option is therefore wrong.
- D
an inter-governmental agency to cater to medical emergencies in war-ravaged regions
Medical emergencies in war are associated with bodies such as the International Committee of the Red Cross or Médecins Sans Frontières, not Amnesty. Amnesty is not an inter-governmental medical agency. This option is not the key.
Summary. Official key is (b) a global Human Rights Movement. Amnesty International is an independent NGO that documents and campaigns against human-rights violations worldwide. It is not a UN refugee agency, not a poverty charity, and not a wartime medical body. Those other mandates belong to UNHCR, development NGOs and humanitarian medical organisations. Only (b) states Amnesty’s role correctly.
