Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions.
Every day on radio, on TV, and in the newspapers, we hear, see, or read about many problems in the world, for example, pollution problems.
Air pollution is the first kind. It mostly comes from fumes released from motorbikes, cars, airplanes, trains, and poisonous gases emitted from factories. Also, waste is dumped anywhere, even in the city where many people are living.
The second pollution problem is sea pollution. Many people earn their living from fishing in the sea, and the fish they catch feed many people. But the sea has become so polluted from oil spills and factory wastes that the fish are dying. This pollution is not only killing the fish, but also affecting those people who eat fish.
Seldom do you find a place nowadays that is not polluted. This problem is growing more difficult every day. We must find a good solution that makes the world a better place to live.
The word “they” in paragraph 3 refers to ________.
A.fish
B.motorbike
C.people
D.factories
