[单项选择]For millennia man has exploited and often destroyed the riches of the land. Now man covets the wealth of the oceans, which cover nearly three-quarters of the earth.

In the seabed, minerals and oil have been proved to exist in great supply. The oceans are a source of pure water and food protein, of drugs and building materials; they are even possibly a living place for man himself and a key to survival for doubling population on the land.
Man may yet learn to use a tiny fraction of this wealth. Unless international law soon determines how it shall be shared, that fraction alone could set off a new age of colonial war. Is
A. gold urges people to make new inventions
B. money is the most important thing in the world
C. people have tried to exploit the sea
D. people did not get much from the sea

Inventors have tried to make it easy for people to fly. Paul Moller has been working on his flying car for 30 years. He now says it is ready for tests. It would take off and land vertically, go 600 miles an hour, and deliver 20 miles to the gallon. A computer would do the actual flying. He says it could be sold next year for about a million dollars.

A. a solar powered engine
B. engine-powered twin fans
