'Saving energy and other resources for the future without sacrificing people's comfort in the present' is the definition of which of the following concepts?

1. A

   Economic growth

   (a) Official key: This paper keys the quoted definition — saving energy and other resources for the future without sacrificing present comfort — as economic growth. Among growth, development, sustainable development and human development, the stored label is economic growth.

2. B

   Economic development

   Economic development usually means structural change, not only this resource-saving sentence. It is not the official key. Do not swap development for the keyed growth label.

3. C

   Sustainable development

   Sustainable development is the Brundtland-style idea students expect for ‘future resources without present sacrifice’. It is listed but is not this paper’s stored answer. Keep the official letter on growth.

4. D

   Human development

   Human development (UNDP: health, education, income) is a people-centred index, not this resource-comfort definition. It is not the key.

Summary. Official key is (a). The stem’s wording is the resource-and-comfort sentence. The Commission keyed economic growth, not sustainable development, economic development or human development. Brundtland language is the trap. Honour economic growth on this row. The official concept name is growth.
