Q.State any four reasons why transportation is important to trade and commerce.

Transportation's importance goes beyond simply 'moving goods' — it enables several deeper economic effects that any four correctly stated answer this question.

Any four of the following, briefly explained, answer this question:

1. Widens the market a producer can sell into, beyond the immediate locality.
2. Enables large-scale specialisation and division of labour, since a region can specialise in what it produces best, relying on transport to bring in everything else.
3. Equalises prices across regions, by moving goods from surplus areas (where prices would otherwise be low) to deficit areas (where prices would otherwise be high).
4. Enables rapid emergency relief movement — medical supplies, food and essential goods can reach affected areas quickly during disasters.
5. Brings raw materials to factories that could not otherwise be located near every raw-material source.

Repeating the same basic idea ('goods reach consumers') in different words instead of identifying genuinely distinct economic effects like specialisation or price equalisation.
