Question VII. Read the passage carefully, then choose the correct answer.
Man is a land animal, but he closely tied to the sea. Throughout history the sea has
served the needs of man. The sea provided man with food and convenient way to travel to
many parts of the world. Today, nearly two thirds of the world’s population live within 80
kilometers of the sea coast.
In the modern technological world, the sea offers many resources to help mankind
survive. Resources on land are beginning to be used up. The sea however, still can be
hoped to supply many of man’s needs.
The list of riches of the sea yet to be developed by man’s technology is impressive. Oil
and gas exploration have been carried out for nearly 30 years. Valuable amounts of
mineral exist on the ocean floor ready to be mined.
Fish farming promises to be a good way to produce large quantities of food. The culture
of fish and shellfish is an ancient skill practised in the past mainly by the Oriental people.
Besides oil and gas, the sea may offer new source of energy. Experts believe that the
warm temperature of the ocean can be used in a way similar to the steam in a steamship.
Ocean currents and waves offer possible use as a source of energy. Technology is enabling
man to explore ever more deeply under the sea. The development of strong, new materials
has made this possible.
The technology to harvest the sea continues to improve. Experts believe that by the year
2020 the problems that prevent us from exploiting fully the food, minerals and energy
sources of the sea will be largely solved.
