The World Health Organization(WHO)planned to study the relationship between the eating habits of the people and the disease.Two doctors were chosen to make the study. They flew to Africa south of the Sahara and during the next two months visited ten countries.They found that serious diseases of poor eating, often mistaken for other diseases, existed in all parts of Africa.The diseases were similar and could therefore all be named kwashiorkor .The diseased children are usually from one to four years old.As the illness progresses, the child's stomach becomes swollen by liquid collecting in the body.The skin changes colour and may break out in open sores.The hair changes colour and starts to fall out.The patient loses all interest in his surroundings and even in food, and becomes so weak that he wants to lie down all the time.Stomach liquids are no longer produced. The doctors reasoned that kwashiorkor was found in the young children of this age in many parts of Africa because of lack of milk or meat.Their mothers gave them foods full of starches instead of greatly needed proteins.They found that the addition of milk to the food of children suffering from kwashiorkor saved many lives. From the passage we learn that kwashiorkor is a disease caused by _ . A) poor living conditions B) lack of proteins in food C) much stomach liquids D) lack of food

I get off the bus and walk a few blocks. I stop when I get to a garage-like place and walk to the metal door with brown paint. I turn the knob and walk in. A thousand eyes look at me as I take my place at the end of the long line. When I finally get up to the window, I hand the officer my ID. "I'm here to visit Mr C. Yes, I'm his daughter." I learn that line by heart. The officer hands me a piece of paper with my name as the visitor and my father's as the prisoner. It tells me which floor to go to. As I get on the elevator, a rush of excitement runs through me. Then I go to the eighth floor, look around and see the faces I see here every Sunday and Thursday. There he is. I stand on tiptoe to get a better view since I can hardly see him. He doesn't look like my father. He's got a beard now and he looks a lot weaker. He's the dad that I see through a window. My dad who is separated from the world. The only place he now knows is his room in the prison. When I look deep into his eyes, I see emptiness and pain. It's difficult to hear him through the thick glass and over everyone else who is trying to talk. We try to carry on a normal conversation about simple things including my day and what I'm doing in school, but we mostly talk about how we can't wait until he gets out. After an hour my time is up. We say our good-byes and love-yous. I get on the bus to go home. My favorite place is where my father is--prison. I know, how can prison be anyone's favorite place? But it is because my father is there. It'll no longer be my favorite place once he gets out, though--home will be. What can we know from the passage? A) The author's father will never go home. B) The author meets her father once a week. C) The author's favorite place will change. D) The author hates her father.

Q: Scientists in Canada say big ocean fish have almost disappeared from the world since the start of industrial fishing in the nineteen-fifties. The scientists found that population of large fish like tuna; swordfish and cod have dropped by ninety percent in the past fifty years. The study took ten years. The researchers gathered records from fishing businesses and governments around the world. The magazineNaturepublished the findings. The scientists say the common method called longline fishing is especially damaging to populations of large fish. This method involves many fishing lines connected to one boat. These wires can be close to one-hundred kilometers long. They hold thousands of sharp metal hooks to catch fish. Longline fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish for every one-hundred hooks. The study says longline fishing boats now might catch one fish per hundred hooks. The scientists say industrial fishing can destroy groups of fish much faster than in the past. The study suggests that whole populations can disappear almost completely from new fishing areas within ten to fifteen years. Ransom Myers of Dalhousie University in Nova Scotia led the study with Boris Worm of Dalhousie and the University of Kiel in Germany. Mister Worm says the destruction could lead to a complete re-organization of ocean life systems. Mister Meyers says the decreased number of large fish is not the only worry. He says even populations that are able to reproduce do not get the chance to live long enough to grow as big as their ancestors . He says not only are there fewer big fish, they are smaller than those of the past. American government scientists say even with the best efforts to protect fish populations, decreases are to be expected. Which of the following shows the fact that the populations of large fish have dropped? A) Today's "large"fish are smaller than those of the past. B) Longline boats now might catch fewer fish every one-hundred hooks. C) Fish even able to reproduce don't have the chance to live longer. D) Japanese boats could catch about ten fish for every 100 hooks.

*Question*
If the world were a village of 1,000 people, it would include: * 584 Asians * 124 Africans * 95 Eastern and Western Europeans * 84 Latin Americans * 55 former Soviets (including Lithuanians, Latvians, Estonians, and other national groups) * 52 North Americans * 6 Australians and New Zealanders The people of the village would speak: * 165 Mandarin * 86 English * 83 Hindu/Urdu * 64 Spanish * 58 Russian * 37 Arabic The above list covers the mother tongues of only half the village. One-third of the people in the village are children, and only 60 are over the age of 65. Just under half of the married women in the village have access to modem equipments. This year 28 babies will be born. Ten people will die, 3 of them for lack of food, 1 from cancer. Two of the deaths will be of babies born within the year. With the 28 births and 10 deaths, the population of the village next year will be 1,018. In this village of 1,000 persons, 200 people receive 75 percent of the income; another 200 receive only 2 percent of the income. About one-third _ clean, safe drinking water. Of the 670 adults in the village, half can not read nor write. The village has a total yearly budget , public and private, of over $3 million--$ 3 ,000 per person if it is distributed evenly. Of the total $3 million: $ 181,000 goes to weapons and warfare $ 159,000 to education $ 132,000 to health care These weapons are under the control of just 100 of the people. The other 900 are watching them with deep anxiety, wondering whether they can learn to get along together. Which of the following is true about Mandarin according to the text? A) Nearly one-third of Asian people speak Mandarin in the village. B) About 8.25 per cent of the people speak Mandarin in the village. C) About 16. 5 per cent of the people speak Mandarin in the village. D) Nearly all the Mandarin-speaking people are from Asia in the village.
