I'm taking a test and have to guess the right answer to the question after the article. Article: Farmer Ed Rawlings smiles as he looks at his orange trees. The young oranges are growing well in Florida's weather. Warm sunshine and gentle rains, along with Ed Rawlings' expert care, will produce a good crop of oranges this year. However, Ed has to guard against Florida's changeable winter weather. In January and February, temperatures can destroy Ed's entire orange crop. Having farmed in Florida for the past 35 years, Ed is prepared for the frost . When temperatures drop below freezing, Ed tries to save his crop by watering his orange trees. The water freezes and forms a thin layer  of ice around the trees. Strange as it may sound, this thin layer of ice actually keeps the fruit warm. What happens is simple. When the trees are watered, the water loses heat and becomes ice. The warmth of the heat it loses is taken in by the fruit and keeps its temperature at a safe level. Ed has effectively used this method to save many orange crops. But Ed still faces difficulties. The trees must be watered at the exact moment the temperature drops to the freezing point. Also, just the right quantity of water must be used. Too much water can form a thicker layer of ice that will break the tree's branches . Another difficulty is that wind blows away the heat, so Ed has to worry about not only when but also how often his trees should be watered, and how much water should be used. Computer technology may help Ed with some of these worries. With equipment , air and soil temperatures and wind speed can be measured. The information is fed into a computer which can calculate  when the temperature will drop below freezing. The computer can correctly decide the quantity of water to be used and how frequently(  ) the trees should be watered. Ed finds looking after his orange trees a lot easier with the help of a computer, and, his customers will have the benefits  of computer--age oranges. Question: The passage is mainly about  _  . Options: A: a farmer expert cares for his orange trees B: the different uses of computers C: growing oranges in Florida's changeable weather D: different ways of frost protection

I'm taking a test and have to guess the right answer to the question after the article. Article: Carbon monoxide poisoning   causes death and injuries around the world. This gas is a problem in all parts of the world that experience cold weather. A few years ago, America's Centers for Disease Control (C. D. C.) studied deaths linked   with carbon monoxide poisoning. It found that the number of carbon monoxide deaths in the United States was greatest in January. The C.D.C. also found that carbon monoxide kills more than four hundred Americans each year. And, it said more than twenty thousand people are taken to hospital for treatment of health problems linked with the gas. Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color, no taste and no smell. It does not cause burning eyes. And it does not cause people to cough. Yet, carbon monoxide gas is very deadly  . It steals the body's ability to use oxygen. Carbon monoxide makes it difficult for the blood to carry oxygen to body tissues  . It does this by linking with the blood. When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it. Damage   to the body can begin very quickly from large amounts   of carbon monoxide. How quickly this can happen depend on how long a person is breathing the gas and how much gas he or she breathes in. Carbon monoxide poisoning has warning signs . But people have to be awake to realize them. Small amounts of the gas will cause a person's head to hurt. He or she may begin to feel tired. Their stomachs may feel sick. The room may appear to be turning around. The person may have trouble thinking clearly. People develop serious headache as the amount of the gas continues to enter their blood. They will begin to feel very tired and sleepy. They may have terrible stomachache. Doctors say carbon monoxide influences people differently. For example a small child will experience health problems or die much sooner than an adult. The general health of the person or his or her age can also be important. Question: Which of the following is TRUE according to the passage? Options: A: Carbon monoxide poisoning seldom happens in cold areas. B: Twenty thousand Americans are killed by carbon monoxide each year. C: Most people know whether there is carbon monoxide in the air. D: Carbon monoxide stops the blood from carrying oxygen to body tissues.
