Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

      Centuries ago, man discovered that removing moisture from food helped to preserve it, and that the easiest way to do this was to expose the food to sun and wind. In this way the North American Indians produced pemmican (dried meat ground into powder and made into cakes), the Scandinavians made stockfish and the Arabs dried dates and apricots.

      All foods contain water - cabbage and other leaf vegetables contain as much as 93% water, potatoes and other root vegetables 80%, lean meat 75% and fish anything from 80% to 60% depending on how fatty it is. If this water is removed, the activity of the bacteria which cause food to go bad is checked.

      Fruit is sun-dried in Asia Minor, Greece, Spain and other Mediterranean countries, and also in California, South Africa and Australia. The methods used vary, but in general the fruit is spread out on trays in drying yards in the hot sun. In order to prevent darkening, pears, peaches and apricots are exposed to the fumes of burning sulphur before drying. Plums for making prunes, and certain varieties of grapes for making raisins and currants, are dipped in an alkaline solution in order to crack the skins of the fruit slightly and remove their wax coating, so increasing the rate of drying.

      Nowadays most foods are dried mechanically; the conventional method of such dehydration is to put food in chambers through which hot air is blown at temperatures of about 110oC at entry to about 45oC at exit. This is the usual method for drying such things as vegetables, minced meat, and fish.

      Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated horizontal steel cylinder or by spraying them into a chamber through which a current of hot air passes. In the first case, the dried material is scraped off the roller as a thin film which is then broken up into small, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder. Where recognizable pieces of meat and vegetables are required, as in soup, the ingredients are dried separately and then mixed.

      Dried foods take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them.

In the process of drying certain kinds of fruits, sulphur fumes help ______.

The history of clinic nutrition, or the study of the relationship between health and how the body takes in and utilizers food substances, can be divided into four distinct eras: the first began in the nineteenth century and extended into the early twentieth century when it was recognized for the first time that food contained constituents that were essential agents. Near the end of this era, research studies demonstrated that rapid weight loss was associated with nitrogen imbalance and could only be rectified by providing adequate protein associate with certain foods.
The second era was initiated in the early decades of the twentieth century and might be called "the vitamin period". Vitamins came to be recognized in foods, endeficiency syndromes were described. As vitamins became recognized as essential food constituents necessary for health, it became tempting to suggest that every disease and condition for which there had been no previous effective treatment might be responsive to vitamin therapy. At the point in time, medical schools started to become more interested in having their curricula integrate nutritional therapies in medicine. Reckless claims were made for effects of vitamins that went far beyond what could actually be achieved from the use of them.
In the third era of nutritional history in the early 1950's to mid-1960's, vitamin therapy began to fall into disrepute. Concomitant with this, nutrition education in medical schools also became less popular. It was just a decade before this that many drug companies had found their vitamins sales skyrocketing and were quick to supply practicing physicians with generous samples of vitamins and literature extolling the virtue of supplementation for a variety health-related conditions. Expectations as to the success of vitamins in disease control were exaggerated. As is known in retrospect, vitamin and mineral therapies are much less effective when applied to health-crisis conditions that when applied to long-term problems of nutrition that lead chronic health problem.

People commonly complain that they never have enough time to accomplish tasks. The hours and minutes seem to slip away before many planned chores get done. According to time management experts, the main reason for this is that most people fail to set priorities about what to do first. They get tied down by trivial, time consuming matters and never complete the important ones.
One simple solution often used by those at the top is to keep lists of tasks to be accomplished daily. These lists order jobs from most essential to least essential and are checked regularly through the day to assess progress. Not only is this an effective way to manage time, but also it serves to give individuals a much deserved sense of satisfaction over their achievements. People who do not keep lists often face the end of the word day with uncertainly over the significance of their accomplishments, which over time can contribute to serious problem in mental and physical health.

Carbon dating can be used to estimate the age of any organic natural material; it has been used successfully in archeology to determine the age of ancient artifacts or fossils as well as in a variety of other fields. The principle underlying the use of carbon dating is that carbon is a part of all living things on Earth. Since a radioactive substance such as carbon-14 has a known half-life, the amount of carbon-14 remaining in an object can be used to date that object.
Carbon-14 has a half-life of 5,570 years, which means that after that number of years, half of the carbon- 14 atoms have decayed into nitrogen-14. It is the ratio of carbon-14 in that substance that indicates the age of the substance. If, for example, in a particular sample the amount of carbon- 14 is roughly equivalent to the amount of nitrogen-14, this indicates that around half of the carbon- 14 has decayed into nitrogen-14, and the sample is approximately 5,570 years old.
Carbon dating cannot be used effectively in dating objects that are older than 80,000 years. When objects are that old, much of the carbon-14 has already decayed into nitrogen-14, and the molecule amount that is left doesn’t provide a reliable measurement of age. In the case of older objects, other age-dating methods are available, methods which use radioactive atoms with longer half-lives than carbon has.

It’s a sound you will probably never hear, a sickened tree sending out a distress signal. But a group of scientists has heard the cries, and they think some insects also hear the trees and are drawn to them like vulture to a dying animal. Researchers with the US Department of Agriculture’s Forest Service fastened sensors to the bark of drought-stricken trees clearly heard distress calls. According to one of the scientists, most parched trees transmit their plight in the 50-hertz to 50-kilohertz range. (The unaided human ear can detect no more than 20 kilohertz). Red oak, maple, white pine, and birch all make slightly different sounds in the form of vibrations at the surface of the wood.
The scientists think that the vibrations are created when the water columns inside tubes that run along the length of the tree break, a result of too little water following through them. These fractured columns send out distinctive vibration pattems. Because some insects communicate at ultrasonic frequencies, they may pick up the trees' vibration and attack the weakened trees. Researchers are now running tests with potted trees that have been deprived of water to see if the sound is what attracts the insects. “Water-stressed trees also smell differently from other trees, and they experience thermal changes, so insects could be responding to something other than sound”, one scientist said.

Clara Barton became known as “ The Angel of the Battlefield” during the American Civil War. Born in Oxford, Massachusetts in 1821, Clara Barton’s interest in helping soldiers on the battlefield began when she was told army stories from her father. Another event that influenced her decision to help soldiers was an accident her brother had. His injuries were cared for by Barton for 2 year. At the time, she was only 11 years old. Barton began teaching school at the age of 15. She taught for 18 years before she moved to Washington, D.C in 1854.
The civil war broke out 6 years later. Immediately, Barton started war service by helping the soldiers with their needs. At the battle of Bull run, Clara Barton received permission from the government to take care of the sick and hurt. Barton did this with great empathy and kindness. She acknowledged each soldier as a person . her endurance and courage on the battlefield were admired by many. When the war ended in 1865 , she used 4 years of her life to assist the government in searching for soldiers who were missing during the war.
The search for missing soldiers and years of hard work made her feeble physically. In 1869, her doctors recommended a trip to Europe for a rest. While she was on vacation , she became involved with the International Red Cross, an organization set up by the Geneva Convention in 1864. Clara Barton realized that the Red Cross would be a best help to the United States. After she returned to the United States, she worked very hard to create an American Red Cross. She talked to government leaders and let American people know about the Red Cross. In 1881, the National Society of the Red Cross was finally established with its headquarters in Washington ,D.C. Clara Barton managed its activities for 23 years.
Barton never let her age stop her from helping people. At the age of 79, she helped food victims in Galveston, Texas. Barton finally resigned from the Red Cross in 1904. She was 92 years old and had truly earned her title “ The Angel of the Battle”.

May 7, 1840 was the birthday of one of the most famous Russian composers of the nineteenth century Peter Illich Tchaikovsky. The son of a mining inspector, Tchaikovsky studied music as a child and later studied composition at the St.Pertersburg Conservatory. His greatest period of productivity occurred between 1876 and 1890, during which time he enjoyed the patronage of Madame von Meck, a woman he never met, who gave him a living stipend of about $1,000.00 a year. Madame von Meck later terminated her friendship with Tchaikovsky, as well as his living allowance, when she, herself, was facing financial difficulties. It was during the time of Madame von Meck’s patronage, however, that Tchaikovsky created the music for which he is most famous, including the music for the ballets of Swan Lake and The Sleeping Beauty.
Tchaikovsky’s music, well known for its rich melodic and sometimes melancholy passages, was one of the first that brought serious dramatic music to dance. Before this, little attention had been given to the music behind the dance. Tchaikovsky died on November 6,1893, ostensibly of cholera, though there are now some scholars who argue that he committed suicide.

One of the highest honors for formalists, writers, and musical composers is the Pulitzer Prize. First awarded in 1927, the Pulitzer Prize has been won by Ernest Hemingway, Harper Lee, John F. Kennedy, and Rodgers and Hammerstein, among others. As with many famous awards, this prize was named after its founder, Joseph Pulitzer.
Joseph Pulitzer’s story, like that of many immigrants to the United States, is one of hardship, hard work and triumph. Born in Hungary, Joseph Pulitzer moved to United States in 1864. He wanted to be a reporter, but he started his American life by fighting in the American Civil War. After the war, Pulitzer worked for the German - language newspaper, the Westliche Post. His skills as a reporter were wonderful, and he soon became a partial owner of the paper.
In 1978, Pulitzer was able to start a newspaper of his own. Right from the first edition, the newspaper took a controversial approach to new. Pulitzer wanted to appeal to the average reader, so he produced exciting stories of scandal and intrigue. Such an approach is commonplace today, but in Pulitzer’s time it was new and different. The approach led to the discovery of many instances of corruption by influential people. Pulitzer ‘paper became very famous and is still produced today.
The success of Joseph Pulitzer’s newspaper made him a very wealthy man, so he wanted to give something back to his profession. Throughout his later years, he worked to establish university programs for the teaching of journalism, and he funded numerous scholarships to assist journalism students. Finally, he wanted to leave a legacy that would encourage writers to remember the importance of quality. On his death, he gave two million dollars to Columbia University so they could award prizes to great writers.
The Pulitzer Prize recipients are a very select group. For most, winning a Pulitzer Prize is the highlight of their career. If an author, journalist, or composer you know has won a Pulitzer Prize, you can be sure they are at the top of their profession.
