Q1. Consider the following statements about types of transport and their characteristics: 1. Air transport is the fastest mode but carries the smallest share of world trade by volume. 2. Maritime transport carries approximately 80% of world trade by volume. 3. Pipeline transport is most efficient for solid bulk commodities like coal and grain. 4. Road transport provides maximum flexibility for last-mile connectivity. Which of the above statements are correct?
Explanation
Statements 1, 2, and 4 are correct. Air transport is fastest but carries <1% of world trade by volume (but ~35% by value). Maritime transport carries ~80% of world trade by volume — it is the backbone of global commerce. Road transport provides unmatched last-mile flexibility. Statement 3 is INCORRECT — pipelines are most efficient for liquids and gases (oil, natural gas), NOT for solid bulk goods like coal and grain.
