Strengthening Your Core
If there is one indication that someone is fit, it is a tight and lean stomach. Men and women alike hope that eating right and putting in hard work at the gym will earn them a perfect six-patch. Unfortunately, the opposite is also true. The rising popularity of fast food has led to an increase of obesity rates and waistlines around the globe. If someone is out of shape, you will notice the extra weight around their midsection. In both cases, a person’s core muscles seem to tell a lot about their fitness and eating habits. Many people associate the core with just the stomach area, but science actually defines it as our body without arms and legs. Although many people want a solid core to look good, the development of these muscles affects many areas of our lives. In athletics and general life for that matter, we all rely on our core muscles heavily to get things done. Studies have shown that athletes who build a powerful core foundation aren’t injured as much. Meanwhile, the benefits of your average Joe may be even greater. Ordinary people use their core muscles for nearly every task they do. This includes picking things up, sitting in a chair, or tying your shoes. Our core muscles provide stability, so we can keep our balance and easily move in any direction. If we neglect them, life can become much more difficult. As a result, we should always consider our core muscles when designing our workouts. However, if you have been sedentary for years, performing thousands of repetitions will probably get you injured. Instead, start off slowly and gradually build up your numbers. An excellent exercise for both beginners and advanced exercisers is the plank. You simply get in an extended pushup position as if you have just finished a rep. Maintain this position, but place the weight on your forearms instead of your hands. Then, hold the position as long as you can. You should feel your core muscles working hard to help your hands and support the weight of your body. In the beginning, you may only be able to hold it for a few seconds, but keep at it. The Guinness World Record for abdominal planking is three hours and seven minutes.

Friendship is a two-sided ________, it lives by give-and-take.

The ability to conduct electricity is one of the key properties of a metal. Other solid material such as silicon can conduct electricity but only effectively at certain temperatures. Also, some substances such as salt (sodium chloride) can conduct when molten or when dissolved in water. The ability of metals to conduct electricity is due to how their atoms bond together. In order to bond together the metal atoms lose at least one of their outermost electrons. This leaves the metal atoms with a positive charge and they are now strictly ions. The lost electrons are free to move in what are known as a sea of electrons. Since the electrons are negatively charged they attract the ions and this is what keeps the structure together.

An electric current is a flow of charge and since the electrons in the sea of electrons are free to move they can be made to flow in one direction when a source of electrical energy such as a battery is connected to the metal. Hence we have an electric current flowing through the wire, and this is what makes metals such good conductors of electricity. The only other common solid conducting material that pencil users are likely to encounter is graphite (what the 'lead' of a pencil is made from). Graphite is a form of carbon and again the carbon atoms bond in such a way that there is a sea of electrons that can be made to flow as an electric current. Likewise, if we have an ionic substance like salt we can make the electrically charged ions flow to create a current but only when those ions are free to move, either when the substance is a liquid or dissolved in water. In its solid state an ionic substance like salt cannot conduct electricity as its charged ions cannot flow.

Electrical insulators are substances that cannot conduct electricity well either, because they contain no charged particles or any charged particles they might contain do not flow easily. Water itself is a poor conductor or electricity as it does not contain a significant amount of fully charged particles (the ends of a water molecule are partly charged but overall the molecule is neutral). However, most water we encounter does contain dissolved charged particles, so it will be more conductive than pure water. Many of the problems that occur when touching electrical devices with wet hands result from the ever-present salt that is left on our skin through perspiration and it dissolves in the water to make it more conductive.

Putting Cars on Autopilot
Automobile accidents are one of the leading causes of death each year. Accidents can occur due to drunk driving, mechanical problems, carelessness, or a whole assortment of other reasons. In the near future, these problems could be solved by eliminating the person behind the wheel. Driverless cars may soon be turning all vehicle owners into “backseat drivers”. Driverless cars are vehicles that use several technologies to operate without human input. Through GPS, they can find a location on a map and plan the best route to get there. They may also use radar to detect other vehicles and avoid them when necessary. One company involved with developing driverless cars is Google. It’s developing a software called Google Chauffer which powers the vehicles. The technology isn’t cheap though, as Google robotic cars contain about $150,000 worth of equipment. In 2012, Google began testing the cars on the road with a highly-skilled driver in the driver’s seat, and a Google engineer in the passenger seat. In case there are any malfunctions, the human driver can step on the brakes or turn the wheel to take control of the automobile. Other car manufacturers are also working on implementing automated options into their cars. For example, the 2014 Mercedes-S class offers advanced cruise control using radar, lane warnings, and even detects, and warns drivers when they appear tired. Many Americans seem open to the idea, as three states have already passed laws that make it legal for driverless cars to be on the road. Still there will be some stumbling blocks to overcome before the roads are controlled by digital decision-makers. Firstly, companies will need to provide proof that driverless cars were tested a lot and are truly safe. Automobile manufacturers will also have to find a way to bring down costs, as few people would be able to afford the equipment required. Driverless cars could also potentially become targets for computer hackers. If a hacker were somehow able to override the software system, they could cause accidents or malfunctions. There are also economic issues to consider. If driverless cars became successful, millions of truck, bus, and taxi drivers would likely lose their jobs. Despite these issues, all indications suggest that it should be just a matter of time before humans are no longer needed behind the wheel.
6. According to the passage, all of the following are true about driverless cars EXCEPT that _________

The Great Debate over GM Foods
One of the hottest topic in agriculture today is genetically modified (GM) foods. GM foods are foods that come from plants that have had their DNA altered using biotechnology. GM foods have been on the market since 1994, when a company called Calgene started selling GM tomatoes. Since then, other GM foods including papaya, corn, and plums to name a few have been developed. The main benefit of GM foods is that they can be a more economical solution than non GM foods. Scientists found a way to modify many plants to make them more resistant to weeds, diseases, and pests. This allows the plants to grow in tougher climates and conditions, which should lead to lower food prices and increase the overall food supply. However, many consumers still have their doubts about GM foods. For one they feel that by eating GM foods people are messing with nature. Until now humans have survived on food that was produced without any interference from science. Even though many lab studies show that GM foods are safe in the short term, opponents feel that not enough long-term testing has been done yet. Another major issue in the GM foods debate is its labelling. Current US laws do not require producers to label their foods as GM. This has upset many consumers who feel they have the right to clearly know how the food they are buying is produced. On the other hand, producers are afraid to label their foods as GM because they feel it will result in less product sales, as people may assume that there is something wrong with GM foods. This controversy is not just on the level of consumers and producers. The issue of non GM foods has also become a block to a major free trade agreement between the US and Europe. GM foods are banned throughout most of Europe, while they are quite common throughout the US. Since many American GM food producers would like to sell their foods overseas in Europe, the US is requesting that European nations eliminate laws banning GM foods. However, many European nations are not fully convinced that these products are safe.
2. According to the passage, why did scientists invent GM foods?

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:
Scientists have developed a new bionic computer chip that can be mated with human cells to combat disease. The tiny device, smaller and thinner than a strand of hair, combines a healthy human cell with an electronic circuitry chip. Doctors can control the activity of the cell by controlling the chip with a computer.
It has long been established that cell members become permeable when exposed to electrical impulses. Researchers have conducted genetic research for years with a trial-and-error process of bombarding cells with electricity in an attempt to introduce foreign substances such as new drug treatments or genetic material. They were unable to apply a particular level of voltage for a particular purpose. With the new invention, the computer sends electrical impulses to the chip, which triggers the physicians to open a cell‘s pores with control.
Researchers hope that eventually they will be able to develop more advanced chips whereby they can choose a particular voltage to activate particular tissues, whether they be muscle, bone, brain, or others. They believe that they will be able to implant multiple chips into a person to deal with one problem or more than one problem.

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.

The word “elaborate” in paragraph 3 is closest in meaning to     .

During the nineteenth century, women in the United States organized and participated in a large number of reform movements, including movements to reorganize the prison system, improve education, ban the sale of alcohol, and, most importantly, free the slaves. Some women saw similarities in the social status of women and slaves. Women like Elizabeth Cady Stanton and Lucy Stone were feminists and abolitionists who supported the rights of both women and blacks. A number of male abolitionists, including William Lloyd Garrison and Wendell Philips, also supported the rights of women to speak and participate equally with men in antislavery activities. Probably more than any other movement, abolitionism offered women a previously denied entry into politics. They became involved primarily in 20 order to better their living conditions and the conditions of others. When the Civil War ended in 1865, the Fourteenth and Fifteenth Amendments to the Constitution adopted in 1868 and 25 1870 granted citizenship and suffrage to blacks but not to women. Discouraged but resolved, feminists influenced more and more women to demand the right to vote. In 1869, the Wyoming Territory had yielded 30to demands by feminists, but eastern states resisted more stubbornly than before. A women's suffrage bill had been presented to every Congress since 1878 but it continually failed to pass until 1920, 35 when the Nineteenth Amendment granted women the right to vote.
