Model Answer

(A) Both A and R are true and R is the correct explanation of A.

Containerisation reduced port handling costs and increased speed of exports, directly making long-distance international trade more economical and boosting it.

Source: Factors That Have Enabled Globalisation, Chapter 4

Explanation

The textbook explicitly states that containers led to "huge reduction in port handling costs and increased the speed with which exports can reach markets," which directly explains why international trade has grown. R correctly and directly explains A, so option (A) is correct. Do not confuse this with (B) — R is not merely a coincidental true fact; it is the actual causal reason for A.
