单选题Exports are either raw materials or manufactured goods. Raw materials are products of the land， such as
cotton， timber or rubber. Some raw materials， such as iron ore， come from mines. These raw materials are
often exported by the countries that produce them to other countries where they are made into manufactured
goods. Some countries produce food for export， for example， meat， sugar， or cereals such as wheat and
maize. These countries are agricultural countries. An agricultural country needs fertile land and a good climate.
A cold， dry climate is not suitable for agriculture.
A country which produces manufactured goods is known as an industrialized country. An industrialized country
cannot always produce enough food for its own needs. In this case， it does not export foodstuffs. Instead it
has to import them. It relies on exports of manufactured products and pays for imports with the money it earns
from the exported goods.
