Today, these are grown in a lot of different countries and they're sold in supermarkets all over the world. They don't seem strange any more! Potatoes were first grown in the Andes in South America. In 1586, they were taken to Europe by explorers . In 1719, they were taken to North America. Before 1719, nobody in North America had ever seen or eaten a potato.

Mouth bacteria grow fast in airless conditions. Oxygen rich saliva  keeps their numbers down. When we sleep, for example, the saliva stream slows, and sulfur  producing bacteria gains the upper hand, producing classic "morning breath".    Alcohol drinking, too much talking, breathing through the mouth during exercise, anything that dries the mouth produces bad breath. So can stress, though it's not understood why. Some people's breath turns sour every time they go on a job interview.    Saliva flow gradually slows with age, which explains why the elderly have more bad breath trouble than younger people do. Babies, however, who make plenty of saliva and whose mouths contain  ly few bacteria have characteristically sweet breath.    For most of us, the simple, dry mouth variety of bad breath is easily cured. Eating or drinking starts saliva and sweeps away many of the bacteria. Breakfast often stops morning breath.    Those with constant dry mouth find that it helps to keep gum, hard candy, or a bottle of water or juice around. Brushing the teeth wipes out dry mouth bad breath because it clears away many of the offending bacteria. Surprisingly, one thing that rarely works is mouthwash. The liquid can mask bad breath smell with its own smell, but the effect lasts no more than an hour. Some mouthwashes claim to kill the bacteria responsible for bad breath. The trouble is, they don't necessarily reach all offending germs. Most bacteria are well protected from mouthwash under thick layers of mucus  . If the mouthwash contains alcohol--as most do--it can worsen the problem by drying out the mouth. Which of the following is mentioned as one of the causes of bad breath? A) Tooth trouble. B) Sulfur rich food. C) Too much exercise. D) Mental pressure.

Northern Europeans spend a lot of time in their cold and cloudy winters planning their summer holidays. They are proud of their healthy color when they return home after the holiday. But they also know that a certain amount of sunshine is good for their bodies and general health. In ancient Greece people knew about the healing  powers of the sun, but this knowledge was lost. At the end of the nineteenth century a Danish doctor, Niels Finsen, began to study the effect of sunlight on certain diseases, especially diseases of the skin. He was interested not only in natural sunlight but also in artificially   produced rays. Sunlight began to play a more important part in curing sick people. A Swiss doctor, Auguste Rollier, made full use of the sun in his hospital at Lysine. Lysine is a small village high up in the Alps. The position is important: the rays of the sun with the greatest healing power are the infra-red   and ultra-violet   rays; but ultra-violet rays are too easily lost in fog and the polluted air near industrial towns. Dr. Roller found that sunlight, fresh air and good food cure a great many diseases. He was particularly successful in curing certain forms of tuberculosis with his "sun-cure". There were a large number of children in Dr. Roller's hospital. He decided to start a school where sick children could be cured and at the same time continue to learn. It was not long before his school was full. In winter, wearing only shorts, socks and boots, the children put on their skis after breakfast and left the hospital. They carried small desks and chairs as well as their school books. Their teacher led them over the snow until they reached a slope which faced the sun and was free from cold winds. There they set out their desks and chairs, and school began. Although they wore hardly any clothes, Roller's pupils were very seldom cold. That was because their bodies were full of energy which they got from the sun. But the doctor knew that sunshine can also be dangerous. If, for example, tuberculosis is... According to the passage, when did sunlight begin to play a more important part in the treatment of disease? A) From ancient times. B) At the end of the nineteenth century. C) Not until this century. D) Only very recently.
