Article: How would we travel without maps? It would be a bit adventurous to set off from Oxford University to go to London Bridge if there wasn't a map of the London Underground at each station. In fact, a lot of the early map-makers were adventurers and explorers, especially in the 15th and 16th centuries. So what did people do before there were maps? Well, it was quite easy to use natural signs like mountains and rivers if you were travelling on foot or riding a horse. People took small boats down rivers and followed coastlines. And it was much more logical to use time, not distance, to measure journeys: the next village is a three-hour ride, for example. In fact, in the earliest maps, people didn't draw landmarks. They drew the stars. It was very easy to see the night sky and use it for navigation . The sky was a lot clearer before the light pollution from cities that we have today. When towns and cities were built, people drew road maps which gave correct distances and directions. The London Underground was opened in 1863 and it also used a road map style. But a man called Henry Beck realized that travelling by train wasn't the same as driving your car across London. Passengers only needed to know which stations to change at. His new design for the Underground map wasn't very popular with the train companies at first. But the passengers loved it and in 1933, 700,000 copies were printed. These days, of course, you can ride a bike, drive a car or go through a forest and know where you are exactly, using a GPS. It's really difficult to get lost! Question: What was drawn in the earliest maps? Yes or no, is the answer "Stars."?
(Answer)
No

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: What does the passage mainly talk about? Yes or no, is the answer "The damage of carbon monoxide and how it works."?
No
