Communication Systems

Correct answer: D. It facilitates the flow of people, goods and ideas

Connectivity is the degree to which places are linked through transport, communication and networks. Its governing idea is flow: better roads, railways, ports, air routes and digital systems reduce barriers and allow people, goods, money, information and ideas to move between regions. Option D is correct because it states the principal geographical function of connectivity. Connectivity does not necessarily increase distance or separate regions; it usually improves interaction and accessibility. It also does not automatically exhaust resources, although transport and communication systems can create environmental impacts that must be managed responsibly.

Correct answer: C. Ease of reaching a place

Accessibility means the ease with which people, goods or information can reach a place or move from it to other places. It depends on factors such as distance, travel time, transport availability, cost, route quality and communication links. Option C is correct because it gives the direct meaning of accessibility. Elevation, soil and age may describe characteristics of a place, but they do not by themselves define how easily that place can be reached. A high place can still be highly accessible if it has good roads, while a low place may be isolated if connections are poor.
