Read the following article and answer the question. 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.

Read the following article and answer the question. Article: Do you know that it is your own immune system working against the virus that makes you uncomfortable when getting a cold, but not the virus itself? So when you have got a strong immune system and the virus is strong enough too, you will possibly get terrible cold symptoms( ) ? Vitamin C won't stop a cold It is claimed that Vitamin C helps by increasing white blood cells. However, many tests have shown that it does not prevent colds. At best, it only slightly reduces the rime of symptoms. Staying indoors won't protect you One of the most likely sources of cold viruses is your computer mouse or desk. A study of the cold virus in offices found that 47% of desktops, 46% of computer mice and 45% of telephones had cold viruses on them. Wrapping up warm won't protect you Colds are more common in autumn and winter. That's because the cool, wet and cold weather drives people indoors, where viruses may more easily jump from one person to another. And the distinct peak in colds is in September and early January, which is likely due to the return of students to schools and colleges after the summer and winter vacation. Old granny's chicken soup is right Granny's chicken soup is an old cure for colds since a long time ago. Scientists say it is true. Chicken soup does help cure a cold. Many canned soups are just efficient as homemade ones. Question: It is _ that makes you uncomfortable when getting a cold. Answer:
