The development of the concept of 'Global Village' is based on

1. A

   Social development

   Social development is part of global integration but is not the base of McLuhan’s ‘global village’. Welfare, literacy and urban change follow faster links; they do not themselves create the metaphor. This option is therefore not the key.

2. B

   Political development

   Political development and world organisations matter for diplomacy, not for the communications thesis behind ‘global village’. Treaties do not shrink distance the way media and transport do. Politics is a consequence, not the keyed base.

3. C

   Transport and Communication Development

   (c) Official key: The ‘global village’ idea rests on transport and communication development. Marshall McLuhan used the phrase for a world shrunk by electronic media; geography textbooks add faster ships, air and telecom. Among the four bases, only this pair matches the concept.

4. D

   International organisations

   International organisations (UN, WTO and the rest) organise cooperation; they are not the technological base of the global-village metaphor. Confusing the UN system with McLuhan’s media thesis is the trap.

Summary. Official key is (c). ‘Global village’ is a communications-and-transport idea: the world feels small because messages and people move fast. Social and political development, and international bodies, ride on that shrinkage; they are not its definition. McLuhan’s electronic media plus modern transport is the keyed base. Other options name related but different fields.
