Which of the following is not typically moved by ships according to the material?

• A. Timber
• B. Crude oil
• C. Iron ore
• D. Coal

Answer: (A)

The main idea here is understanding what kinds of cargo sea transport is most efficient for. Crude oil, iron ore, and coal are classic bulk cargoes moved by ships because oceans handle very large, heavy quantities in a single voyage. Oil is carried in purpose-built tankers that keep the liquid safely contained and easy to unload. Iron ore and coal go into bulk carriers with wide holds designed to maximize on-board volume and speed up loading and discharge. These commodities typically cycle between large production regions and major consuming markets, making sea transport the most economical option.

Timber, as treated in this material, isn’t listed as a typical sea bulk cargo. While it can be shipped by sea in various forms (logs, lumber, containers), the material distinguishes it from the usual sea-moving bulk commodities like crude oil, iron ore, and coal.
