I'm taking a test and have to guess the right answer to the question after the article. Article: Sub-Saharan Africa has the world's highest hunger rate. But according to a new report, African farmers also have ideas that could help the world fight hunger and poverty. Danielle Nierenberg from the Worldwatch Institute in Washington spent a year visiting twenty-five countries south of the Sahara. In Nairobi, Kenya, for example, Ms Nierenberg found women farmers growing vegetables just outside their doorsteps in the Kibera settlement. She says they are finding ways to make their lives better. The women feed their families and sell their _ They use the money to send their children to school. Last year, about 925,000,000 people worldwide did not get enough to eat. Half of all people in the world now live in and around cities. Researchers like Ms Nierenberg are looking increasingly at creative ideas to feed those who don't have enough good food to eat. She says there are a lot of lessons that people in the Western world can learn from Africa. And what they are doing can certainly be done in other developing countries. Farmers in the developing world lose between twenty and forty percent of their harvest before it ever reaches market. There are many reasons why food gets wasted. Farmers are without electricity and cold storage. They lack good seeds and fertilizer. They lack good roads. Conditions like these keep small farmers in poverty. Ms Nierenberg says more attention needs to be paid to protecting harvests. She says, "Given all that we invest in producing food in the first place, we need to devote the same amount of attention to making sure that it is not wasted." In Nigeria, village processing centers are helping farmers reduce their losses and earn more money. They centers process cassava, a root vegetable, into basic food products. In Uganda, the Worldwatch report says some schools are teaching children how to grow local kinds of crops. And in South Africa and Kenya the report praises the breeding of local kinds of livestock. These animals may produce less milk or meat than other breeds, but they can... Question: Which of the following statements is NOT true according to the passage? Options: A: Farmers in developing world often lose some of their harvest B: Small farmers in developing countries often suffer poverty. C: Farmers should pay more attention to protecting their harvest D: Attention should be paid to saving food instead of producing food

I'm taking a test and have to guess the right answer to the question after the article. Article: The sea horse is a magical animal, which has puzzled people for thousands of years. In ancient Rome sea horses were believed to be the babies of Neptune's horses. And Neptune was the god of the ocean. Now we know they are not horses at all -- they are a kind of fish. They still seem as magical as ever, especially to divers who have watched them horsing around in the sea. But today, sea horse populations face an uncertain future. Fishermen are catching too many of them, and their undersea habitats are being destroyed. At least 20 million sea horses are taken from the ocean each year. More than 95% are used for traditional medicines in Asian countries. The sea horses are usually dried and then made into powder which is used to treat such problems as asthma , throat infections, skin diseases and cuts. How well the medicines work is unclear. Sea horses are also bought and sold in large numbers as pets. Sea horse expert Amanda Vincent warns against buying pet sea horses. "A lot of people treat them as if they're goldfish," she says. But sea horses require very special care and live food. Most captive sea horses _ diseases and die. Sea horse experts are trying to teach fishermen to become sea horse farmers. Instead of pulling nets of sea horses from the ocean, fishermen could learn to raise them in specially designed saltwater "farms". That way, fishermen would have sea horses to sell, but ocean populations would not be hurt. Vincent and her team have only discovered the 35 different species of sea horses, and they still have plenty of sea horse secrets left to unlock. That is why, Vincent told TFK, protecting future sea horse populations is especially important: "I promise your readers that by the time they grow up to be marine biologists, we'll still have a lot to learn." Question: Which of the following is NOT true according to the passage? Options: A: People in Asian countries hunt sea horses for food. B: Most sea horses caught are used as medicine. C: The effects of the powder of sea horses are uncertain. D: 35 different kinds of sea horses have been discovered.

I'm taking a test and have to guess the right answer to the question after the article. Article: The word "conservation" has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish idea that the treasures were "limitless" and could "last forever". Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others. Fifty years ago, nature study was not part of school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word "conservation" had nothing of the meaning that it has for us today. For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers. Conservation should be made part of everybody's daily life. To know about the water table in ground is just as important to us as a knowledge of the basic math formulas . We need to know why all watersheds need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because _ In a word, it should be our goal to restore as much of the original beauty of nature as we can. Question: According to the author, the greatest mistake of our forefathers was that _ . Options: A: they had no idea about scientific forestry B: they had little or no sense of environmental protection C: they were not aware of the importance of nature study D: they had no idea of how to make good use of raw materials
