Lifelines of National Economy
For a long time, trade and transport were restricted to a limited space. With the development in science and technology, the area of influence of trade and transport expanded far and wide.

- (12.2) Pick the key phrase "socio-cultural plurality" from the passage and link it to railways/airways/waterways connecting people.
- (12.3) This is 2 marks, so give 3–4 points. Examiners look for: communication as complementary to transport, specific examples (radio, TV, internet), and the link to socio-economic progress. Always use examples from the passage itself in case-study questions — do not bring outside facts.
