The LED Lighting Revolution
If you have picked up any electronics magazines recently, you have probably heard about LEDs; yet chances are, you probably don’t realize why they are so special. The truth is that these tiny light bulbs are helping to improve watches, remote controls, televisions, and a host of other projects. Diodes are components that enable energy to flow in one direction, while simultaneously blocking the current from the opposite direction. This is similar to how a valve works on a faucet. If electronic manufacturers require currents to flow in several directions, then multiple diodes will be included in the circuit design. With LEDs, every time a current passes through them, a light is emitted. LED is short for light-emitting diode. Although they have only recently waves in the past decade or so, early models have been around since 1962. There are several benefits that LEDs offer when compared to incandescent or fluorescent lighting. For starters, they have extremely long-life spans in the range of l00,000 hours even in the toughest conditions. They also require far less energy than power sources, which can save users money over the long run. Since LEDs don’t contain moving parts like other bulbs, they can withstand heavy impacts without getting damaged. Finally, they don’t require any _warm-up time_ so they instantly light up when switched on. The only drawback is that they are still a more expensive to purchase at the moment. LEDs were first used on digital clocks, but they have come a long way since then. They have certainly done a lot to improve TV technology. LED TVs have been a hit because they can be built extremely thin, yet also offer power-saving benefits. LED TVs also provide a wider range of colour, which allows for more lifelike and vivid images. In the future, organic LEDs, or OLEDs, will bring additional benefits for viewers. OLEDs are even more flexible than LEDs, so manufacturers will be able to create bent display screens and lights. Therefore, you will be able to roll up your living room TV set and pack it in your suitcase. In other words, LED and OLED technology will likely be lighting up your life for years to come.

It’s in Your Genes
Every human being has about 25,000 genes. Your genes are part of your DNA. They give your body instructions on how to develop. For example, if your genes tell your body to build long, thin fingers, then you will have long, thin fingers. Your genes come from your parents, and they decide everything about you. They decide your hair colour, your eye colour, your height, and so on. Genes are still a bit of a mystery to scientists, but they are learning new things about them all the time. One issue that people often debate is this: Do our genes influence our personalities? These days, most people agree that the answer to this question is yes. Recent studies have shown that genes especially influence our self-control and our sense of purpose. Your sense of purpose is your desire to have goals in your life. If a person really wants to accomplish something and do well in life, he or she has a sense of purpose. A person who does not care about goals has no sense of purpose. Although scientists agree that our genes influence our personalities, there is another question. How much do they influence us? Can we control ourselves, or do our genes control us? People everywhere are still debating this issue. So far, we don’t really have an answer. Genes also affect your health. If a gene has a problem, it is called a mutated gene. Some mutated genes can cause diseases. That is why if a person has a certain health problem, his or her child is more likely to have that same problem. The child also has the mutated gene. As scientists and doctors learn more about genes, they are also developing a new kind of medicine: gene therapy. Therapy is help for a mental or a physical problem. Gene therapy means fixing or replacing mutated genes. Scientists are still experimenting on gene therapy. It is possible that in the future, gene therapy will help doctors prevent and cure diseases that are caused by mutated genes.

Cleaning the World’s Oceans
Imagine taking a romantic walk on the beach with your loved one. As the sun begins to set, you hope to treasure this moment forever. Just then, your bare feet stumble over something and you hear a crack. You have just stepped upon a plastic soda bottle and some junk that the tide has washed ashore. Scenarios like this are happening more frequently due to an access amount of sea rubbish, and the worst of it is found far from land. The increasing accumulation of garbage in oceans is due to a number of factors. Studies suggest that 80 percent of all debris originated on land. The majority of this waste is in the form of plastics. This is particularly troublesome because plastic does not degrade at the same rate that other materials do. Therefore, these articles will remain there for quite some time. Some of the pollution is caused accidentally. For example, about 10,000 product-filled containers are lost at sea every year by freight ships. In other cases, the littering is more deliberate, such as the moment when people toss things into the water from boats or land. One of the most startling discoveries of recent years was an area which is now dubbed the Great Pacific Garbage Patch. It is a large collection of marine debris that collected in the North Pacific Ocean. Although the patch is quite massive, it is undetectable from satellites in space because most of the rubbish is underneath the surface. It was discovered in 1997 by a man who happened to spot it while returning home from a sailing race. The patch formed as a result of rubbish being carried by currents and then getting trapped in the area. Thankfully, the problem of ocean garbage is not being ignored. Organizations like the National Oceanic and Atmospheric Association (NOAA) are taking action. It has funded 76 projects that take an aggressive approach to eliminating sea rubbish. Since 2006, it has removed 3,814 metric tons of marine debris from oceans. Methods of rubbish removal include using machines that skim the surface of ocean waters and remove any drifting materials found. In addition, special traps are set by the mouths of rivers to snatch rubbish before it reaches the sea. If everyone does their part, sea rubbish seems like an issue that can be resolved.

Is It Safe?
Fracking is a way of getting energy from the ground. First, a special liquid is put into the ground. This liquid cracks rocks under the ground. After the rocks are cracked, oil moves through the cracks. Then it is much easier to take the oil from the ground. Fracking was started in 1947. These days, we are doing more and more fracking. That is why everyone is suddenly talking about it. A lot of people say that fracking is a good way to get energy. There is some gas that is very difficult to take from the ground. If we didn’t use fracking, we would not be able to get this oil. They say that because the world need more energy, we have to use fracking. Also, it is said that fracking creates a lot of jobs. However, many people are against fracking. They say that fracking’s “special liquid” pollutes the ground, the water, and the air. People who live near fracking areas could have health problems. Moreover, fracking is very loud. In some countries, fracking is now illegal. The first country to make fracking illegal was France. They did that in 2011. In other countries like England, fracking is legal, but there are many rules that control it. Other countries are waiting to learn more about fracking before they decide whether or not to allow it. However, fracking is very big in the United States. The US is number one fracking country in the world. People who support fracking say that it can be very safe. They say that first, we need strong laws to make sure that fracking is always done safely. Second, they say that fracking needs safe methods and good technology. It is said by many that after we develop these things, fracking will be great for the whole world. However, other people want fracking to be illegal everywhere. They say that it will never be safe. We still don’t know enough about fracking. After we learn more about it, we can decide whether it is really a safe way to get energy or not.

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.

All of the following are mentioned as places in which memories are stored EXCEPT the     .

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:
As working women continue to receive better and better wages, housewives still work at home without receiving pay – checks. Should a woman who works at home, doing the housework and caring for children, be paid for her service? In a 1986 study at Cornell University, sociologists found that the value of the services of a housewife averaged $ 11,600 a year. This rate was based on a family composed of a husband, wife, and three young children. The $ 11,600 is what the husband would have to pay if he hired others to take over his wife’s household chores. The researchers concluded that it would be fair for husbands to pay wives according to federal guidelines for minimum wages.
Another plan for rewarding women who work at home has been suggested by a former Secretary of Health and Human Services. He says that full-time housewives should be allowed to pay social security taxes, with their employers contributing part of the payment. He feels that the present system is unfair. He said, “ If you stay at home and raise a family, nobody will give you credit for it.”

According to the researchers, husbands should     .
