Cold storage, or refrigeration, is keeping food at temperatures between 32 and 45 degrees F in order to delay the growth of microorganisms - bacteria, molds, and yeast - that cause food to spoil. Refrigeration produces few changes in food, so meats, fish, eggs, milk, fruits, and vegetables keep their original flavor, color, and nutrition. Before artificial refrigeration was invented, people stored perishable food with ice or snow to lengthen its storage time. Preserving food by keeping it in an ice-filled pit is a 4,000-year-old art. Cold storage areas were built in basements, cellars, or caves, lined with wood or straw, and packed with ice. The ice was transported from mountains, or harvested from local lakes or rivers, and delivered in large blocks to homes and businesses.
Artificial refrigeration is the process of removing heat from a substance, container, or enclosed area, to lower its temperature. The heat is moved from the inside of the container to the outside. A refrigerator uses the evaporation of a volatile liquid, or refrigerant, to absorb heat. In most types of refrigerators, the refrigerant is compressed, pumped through a pipe, and allowed to vaporize. As the liquid turns to vapor, it loses heat and gets colder because the molecules of vapor use energy to leave the liquid. The molecules left behind have less energy and so the liquid becomes colder. Thus, the air inside the refrigerator is chilled.
Scientists and inventors from around the world developed artificial refrigeration during the eighteenth and nineteenth centuries. William Cullen demonstrated artificial refrigeration in Scotland in 1748, when he let ethyl ether boil into a partial vacuum. In 1805, American inventor Oliver Evans designed the first refrigeration machine that used vapor instead of liquid. In 1842, physician John Gorrie used Evans's design to create an air-cooling apparatus to treat yellow-fever patients in a Florida hospital. Gorrie later left his medical practice and experimented with ice making, and in 1851 he was granted the first U.S. patent for mechanical refrigeration. In the same year, an Australian printer, James Harrison, built an ether refrigerator after noticing that when he cleaned his type with ether it became very cold as the ether evaporated. Five years later, Harrison introduced vapor-compression refrigeration to the brewing and meatpacking industries.
Brewing was the first industry in the United States to use mechanical refrigeration extensively, and in the 1870s, commercial refrigeration was primarily directed at breweries. German-born Adolphus Busch was the first to use artificial refrigeration at his brewery in St. Louis. Before refrigeration, brewers stored their beer in caves, and production was constrained by the amount of available cave space. Brewing was strictly a local business since beer was highly perishable and shipping it any distance would result in spoilage. Busch solved the storage problem with the commercial vapor- compression refrigerator. He solved the shipping problem with the newly invented refrigerated railcar, which was insulated with ice bunkers in each end. Air came in on the top, passed through the bunkers, and circulated through the car by gravity. In solving Busch's spoilage and storage problems, refrigeration also revolutionized an entire industry. By 1891, nearly every brewery was equipped with mechanical refrigerating machines.
The refrigerators of today rely on the same basic principle of cooling caused by the rapid evaporation and expansion of gases. Until 1929, refrigerators used toxic gases - ammonia, methyl chloride, and sulfur dioxide - as refrigerants. After those gases accidentally killed several people, chlorofluorocarbons (CFCs) became the standard refrigerant. However, they were found to be harmful to the earth's

The Great Energy Debate
Modern civilization is heavily dependent on energy. Without reliable power sources, we couldn’t operate machines, use transportation, communicate via Internet, or do many other things. Although everyone recognizes the importance of energy, deciding what kind of energy the world should use in the future is not a simple task. The two leading candidates for this role are green energy and nuclear energy. Currently, most of the energy we use is derived from fossil fuels. Although this energy source has got us this far, there are several problems with it. For starters, it is a finite resource which is quickly running out. Some analysts have even estimated that the Earth could run out of coal and oil within the next 50 years. Burning fossil fuels also creates large amount of pollution, which is harmful to the environment. Although fossil fuels still provide the majority of our power, governments are seeking better energy sources to use going forward. Green energy is one option that is becoming increasingly attractive. It includes technologies such as solar, wind, and hydro power. These are seen as clean sources of energy because they cause very little pollution. In addition, they are completely renewable, so there is no danger that it will run out. The major disadvantage with green energy sources is that they are not cheap. The other alternative is nuclear power. Like green energy, it is also a renewable source of power that will not run out, and it also doesn’t produce air pollution. In addition, nuclear power is more reliable than green energy, as it doesn’t depend on sunshine, rain, or wind to operate. The major issues with nuclear power are safety concerns and nuclear waste. Nuclear power plants create a considerable amount of nuclear waste which is extremely hazardous to people’s health. If they happen to have a meltdown, this could destroy the surrounding area for years to come. The recent nuclear disaster in Fukushima, Japan brought this reality into the spotlight once again. In response, Germany announced it would close down eight of its nuclear plants immediately, and close the rest by 2022. Meanwhile, other nations refuse to give up on nuclear power, stating that these disasters are rare. The debate of whether to use green or nuclear power will likely continue for some time. In the end, it is quite possible that both energy sources will be used to fuel our planet.

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:
Most people can remember a phone number for up to trirty seconds. When this short amount of time elapses, however, the numbers are eerased from the memory. How did the information get there in the first place? Information that makes its way to the short term memory (STM) does so via the sensory storage area. The brain has a filter which only allows atimuli that is of immediate interest to pass on to the STM, also known as the working memory.
There is much debate about the capacity an duration of the short term memory. The most accepted theory comes from George A.Miller, a cognitive psychologist who suggested that humans can remember approximately seven chunks of information. A chunk is defined as a meaningful unit of information, such as a word or nam rather than just a letter or number. Modern theorists suggest that one can increase the capacity of the short term memory by chunking or classifying similar information together. By organizing information, one can optimize the STM, and improve the chances of a memory being passed on to long term storage.
When making a conscious effort to memorize something, such as information for an exam, many people engage in “rote rehearsal”. By repeating something over and over again, one is able to keep a memory alive. Unfortunately, this type of memory maintenance only succeeds if there are no interruptions. As soon as a person stops rehearsing the information, it has the tendency to disappear. When a pen and paper are not handy, people often attempt to remember a phone number by repeating it aloud. If the doorbell rings or the dog barks to come in before a person has the opportunity to make a phone call, he will likely forget the number instantly. Therefore, rote rehearsal is not an efficient way to pass information from the short term to long term memory. A better way is to practice “elaborate rehearsal”. This involves assigning semantic meaning to a piece of information so that it can be filed along with other pre-existing long term memories.
Encoding information semantically also makes it more retrievable. Retrieving information can be done by rocognition or recall. Humans can easily recall memories that are stored in the long term memory and used often; however, if a memory seems to be forgotten, it may eventually be retrieved by prompting. The more cues a person is given (such as pictures), the more likely a memory can be retrieved. This is why multiple choise tests are often used for subjects that require a lot of memorization.

Which of the following is NOT supported by the passage?

Read the passage carefully and choose the correct answer.

I was born to dance. I've been dancing all my life, ever since my mother, who gave up a dancing career on the stage when she married my father, picked me up and twirled me around as an infant. As much as I loved dancing with her, her greatest gift to me was her "unconditional love" during her lifetime.

My parents divorced after only 5 years of marriage, but my father remarried a lovely lady who also loved to dance. They used to take me to a dancing club where I would listen to the music and watch them dance-occasionally my stepmother, Mary, invited me to dance.

I also met my wife, Charlotte, in a dancing party. I danced with her for about 15 minutes, and during that brief span, I realized that I fell in love with her. We kept dancing throughout our marriage. My earliest memories of dancing with my daughters started when I came home from work to our small home in Marblehead, Massachusetts, and my daughter Laura was about 3 years old. It was very relaxing for me. to turn on the record player, pick up Laura in my arms, and dance her around the room!

Our family danced a lot. My daughters, Laura and Anne, and I continued to dance on every occasion. One favorite memory I have of dancing with Laura and Anne was when I took each of them when they were seniors in high school to the Daddy-Daughter dance. We won both dance competitions!

As their father, I have tried to provide my daughters with unconditional love, as my Mother provided to me, endless emotional and loving support, and good educations and life experiences which have helped prepare them for happy and successful adult lives. Being a father who is worthy of their love and respect, I consider fatherhood a privilege, not an entitlement.

In 1994, my oldest daughter Laura gave me a lovely book, which I still have, entitled "Fathers and Daughters." My Father's Day suggestion to every father is to dance with your daughters at every opportunity. It will not only bring you closer, it will give them memories of you “to hang onto" long after we are gone.

Read the following passage and choose the best answer (A, B, C, D):
Cholera, a highly infectious disease, has resulted in millions of deaths time after time over centuries. It is caused by the bacterium Vibrio cholera, first isolated by Robert Koch in 1883. The organism enters the body through the digestive tract when contaminated food or water is ingested.The bacteria multiply in the digestive tract and establish infection. As they die, they release a potent toxin that leads to severe diarrhea and vomiting. This results in extreme dehydration, muscle cramps, kidney failure, collapse, and sometimes death. If the disease is treated promptly, death is less likely. In many countries, a common source of the organism is raw or poorly cooked seafood taken from contaminated waters. The disease is especially prevalent after a natural disaster or other destruction that results in a lack of fresh water. Sewer systems fail, and waste travels into rivers or streams; piped water is not available so people must take their drinking and cooking water from rivers or streams. Because people frequently develop communities along waterways, the disease can be spread easily from one community to the next community downstream, resulting in serious epidemics
