Still, 1 was struck by a report which concluded that today's children are significantly more anxious than children in the 1950s. In fact, the analysis showed, normal children between 9 and 17 have a higher level of anxiety today than children who were treated for mental illness 50 years ago. Why are America's kids so stressed? The report cites two main causes: increasing physical isolation brought on by high divorce rates and less involvement in community, and a growing perception that the world is a more dangerous place.

Read the following article and answer the question. Article: Have you ever imagined what the world will be in the near future? A recent study shows that the world in 2100 will be more crowded, more polluted and less stable ecologically than the world we live in now. Visible ahead is serious stress involving population, resource and environment. Despite greater food output, people in the world will be poorer in many ways than they are today. For hundred of millions of the extremely poor, the outlook for food and other necessities of life will be no better, for many it will be worse. While the economies of the developing countries are expected to grow at a faster rate than those of the industrialized nation, the total national product per head in most less developed countries remains low. The existing gap between the rich and poor nations will further widen. World food production is estimated to increase by 90 percent from 2000 to 2100. Most of that increase goes to the countries that already have higher per-head food consumption. Meanwhile, per-head consumption of food in the developing countries will scarcely improve or will actually fall far below the present inadequate level. What is worse is that prices for food are expected to double. As a result, many less developed countries will have increasing difficulties meeting energy needs. For the one quarter of mankind that depends primarily on wood for fuel, the outlook is not hopeful. Regional water shortage will become more sever. In the 1970-2100 period population growth will require twice as much water as it does today in nearly half the world. Still greater increases would be needed to improve standards of living. Development of new water supply will become more costly. Question: In the 2000-2100 period, the large proportion of global increase of food production goes _ . Answer:
OPTIONS:
- to 90 percent
- to any country in the world that needs it
- to developing countries
- to those countries that already have high per-head consumption

Answer: to those countries that already have high per-head consumption

Read the following article and answer the question. Article: The sun is shining when I get on No. 151 bus. We passengers sit jammed together in heavy clothes. No one speaks. That's one of the unwritten rules of Chicago _ . Although we see the same faces every day, we prefer to hide behind our newspapers. The phenomenon is striking: people who sit so close together are using those thin sheets of newsprint to keep their distance. As the bus approaches the Magnificent Mile, a voice suddenly rings out: "Attention! Attention!" Papers rattle . Necks crane . "This is your driver speaking." We look at the back of the driver's head. His voice has authority. "All of you put your papers down." The papers come down, an inch at a time. The driver waits. The papers are folded and placed on our laps. "Now, turn and face the person next to you. Go ahead." Amazingly, we all do it. Still, no one smiles. I face an older woman, her head wrapped tightly in a red scarf. I see her nearly every day. Our eyes meet. We wait, unblinking, for the next order from the driver. "Now, repeat after me..." It is a command, delivered in the tones of a drill sergeant . "Good morning, neighbor!" Our voices are weak and timid. For many of us, these are the first words we have spoken today. But we say them at the same time, like schoolchildren, to the strangers beside us. We smile and can't help it. We have said it; the barrier has been broken. Good morning, neighbor. It is not so hard after all. Some of us repeat it. Others shake hands. Many laugh. The bus driver says nothing more. He doesn't need to. Not a single newspaper goes back up. I hear laughter, a warm sound I have never heard before on bus No. 151. This day is starting off better than most. Question: Which of the following is true according to the passage? Answer:

- The passengers didn't follow the driver's instruction at first.
- The passengers were physically close together but mentally they kept each other at a terrible distance.

The passengers were physically close together but mentally they kept each other at a terrible distance.
