Question 5. The story at the end of the passage implies that _____. ----- Passage 1 ----- (Para. 1)The air is polluted. The earth is poisoned. Water is unsafe to drink and garbage is burying the civilization that produced it. (Para. 2)Our environment is being polluted faster than nature and man’s efforts can prevent it. Time is bringing us more people, and more people will bring us more industry. More people and more industry will bring us more motorcars, larger cities, and the growing use of man-made materials. This is happening not only in advanced societies but also among the developing nations as they become industrialized. (Para. 3)Now many scientists are worrying about the environment. Some experts declare that the balance of nature is being so upset that the very survival of human beings is in danger. What can solve this problem? The fact is that pollution is caused by man — by his greed and modern way of life. We make “increasing industrialization” our chief aim. For its sake we are willing to sacrifice everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from the country into cities, eager for the benefits of modern society. But as our technological achievements have grown in the last twenty years, so at that time pollution has become a serious problem. (Para. 4)Isn’t it time we stopped asking ourselves where we are going and why? It reminds one of the stories about the airline pilot who told his passengers over the loud speakers, “I’ve some good news and some bad news. The good news is that we’re making rapid progress at 530 miles per hour. The bad news is that we’re lost and don’t know where we’re going.” The sad fact is that this becomes a true story when applied to our modern society. ----- Question 5. The story at the end of the passage implies that _____.
A.
while making progress, modern people should pay close attention to pollution
B.
we should stop sometimes to ask where we are going and why
C.
the bad news is also the good news
D.
pollution has become a serious problem
