The Science of Yawning Have you yawned today? If you can't remember or perhaps haven't noticed, you're similar to most Americans. According to a 2007 study, yawning is considered a basic bodily function, such as scratching an itch or crossing one's legs, and people hardly make note of the act. Despite its normality in our daily routines, the question regarding why yawning occurs still has not been answered with certainty. Interestingly enough, little research has been paid to studying yawning, due to a debate surrounding its importance. Many scientists disagree on the importance surrounding research for yawning. Those against the research believe that it will not greatly impact the scientific and medicinal communities, while others believe that there is a case to be made for the possible physiological significance of a somewhat pointless act. There are a few possible causes as to why one yawns, and even fewer theories related to the evolutionary reason for yawning. The most established theory is that yawning helps a person increase his or hers state of alertness. This is one reason as to why yawning has been associated with sleepiness, or when a person is extremely fatigued. In fact, one famous study has suggested that yawning may have developed as a way of keeping animals alert to possible predators. This gives way to the "contagious" yawn theory, which involves an instinctual reaction to warn another member of the "herd" to stay alert in times of danger. These evolutionary theories are also connected to theories regarding empathy. Various studies have shown that spatial proximity in socially close primates is an indicator of yawn contagion. Other scientists believe that yawning is a sign of the body regulating its temperature and cooling itself down. Neuroscientists have attributed yawning to another possible theory regarding the neurotransmitters in the brain. They believe that chemicals responsible for yawning, including serotonin and dopamine, also cause feelings such as hunger and happiness. Thus, as more of these compounds are activated in the brain, the more frequently a person yawns. In one psychological study on the effects of antidepressant medication, researchers found that people undergoing withdrawal from opioids and those taking serotonin reuptake inhibitors (SSRIs) yawned more often than the people in the control group. This can give way to the idea that chemicals in the brain-especially serotonin-can have an impact on the frequency of yawning. Yawning continues to be an interesting phenomenon with a plethora of possible causes. Theories ranging from chemical balances to empathy relation are all within the realms of possible reasons as to why people yawn, but scientists will most likely study these theories for decades to come. Until a conclusive, definitive answer is reached, it may be safe to assume that yawning acts as a diverse linguistic signal that can represent various functional outcomes. Which of the following is a logical conclusion based on the passage?


A) More research needs to be done before one can pinpoint the exact cause of yawning.
B) Scientists will most likely not dedicate more time to studying the causes of yawning.
C) Most scientists are against devoting more research to studying the causes of yawning.
D) Theories regarding the link between evolutionary and empathy reasons behind yawning are the most probable.

Rachel Carson Rachel Carson (1907-1964) was an American marine biologist, conservationist, and author. She was born on a family farm in Pennsylvania and spent her youth exploring the countryside and writing stories, often about animals. It seems as if Carson was born to be an author. By the age of ten, she had already had her first book published. She began her adult career as an aquatic biologist in the U.S. Bureau of Fisheries, but became a full-time writer by the 1950s. More than anything else, she was interested in what can happen when, as she put it, "Things go out of kilter." Because of this, she began work on her groundbreaking book Silent Spring. Developed in 1939, DDT was the most potent pesticide that world had ever known. It showed just how vulnerable nature was to the actions of humanity. While most pesticides of the day killed only one or two types of insects, DDT could kill hundreds. Originally used only by the military to clear South Pacific islands of malaria-causing insects during World War Two, it was cleared for civilian use in 1945. Carson grew justifiably more and more concerned about DDT as its effects on the environment slowly became known. She tried to publish magazine articles to raise the alarm about the poison, but no one would publish her work. Having gathered a vast amount of research on the subject, Carson started a four-year writing odyssey that culminated with the publishing of Silent Spring in 1962. Carson described how a single application of DDT could poison the environment for weeks or even months. It could enter water sources and remain toxic even when diluted. Ultimately, it accumulated in the fatty tissues of animals-including human beings-and caused cancer and genetic damage. The book's most famous chapter, "A Fable for Tomorrow," described an American town where all life-even human children-had been "silenced" from the deleterious effects of the poison. The reaction from the chemical industry was immediate. A major chemical manufacturer published a response to Silent Spring with a brochure that made fun of Carson's work. It described a world that was plagued by famine, disease, and insect swarms because chemical pesticides had been banned. In spite of this backlash, her careful work paid off. DDT was ultimately banned after President John F. Kennedy ordered a committee to investigate the effects of the chemical on the environment. But perhaps the most important legacy of her book was a new awareness of humanity's potential to inflict damage on the environment. Before the book, conservation had never garnered much public interest. But the problems that Carson wrote about-water contamination, cancer, and mass extinction-could not be ignored. For the first time, the urgent need to regulate industry to protect the environment became accepted. And from this, the modern environmental movement was born. Which of the following sentences contains an opinion?


A) Developed in 1939, DDT was the most potent pesticide that the world had ever known.

Most of us get a dirty look every so often, and we usually don't think much of it. But in many places around the world, "the evil eye" is taken very seriously and requires special action to avoid harm-or even death. Simply put, the evil eye is a look given by someone that is said to convey the power of a magical curse and cause some type of misfortune for another person. According to tradition, babies and children are most susceptible to harm from the evil eye. In many countries, including Greece, Romania, and India, praising a child publicly can invite the attention of the evil eye. In order to ward off the evil eye, parents of thoughtlessly praised children may ask the person who gave the compliment to spit in the child's face! In this way, the child's status is reduced, thus eliminating the need to give the child the evil eye. The best way to deal with the evil eye is to avoid it altogether. Since that's not always possible, lucky charms and amulets-often blue to symbolize heaven or godliness-can be worn. Whatever the truth regarding the evil eye, these charms should be worn at all times. After all, they're beautiful and can act as a great conversation starter! Which of the following statements best describes an argument made in the passage?


A) The evil eye can be cast on children who are complimented too much.
B) The evil eye is considered dangerous but not fatal.
C) The evil eye is a look that can actually empower some victims.
D) The evil eye probably originated in Greece and moved east to India.

During the 18th century, toll roads began appearing all over England, spreading from London all the way to Scotland. But these roads were made of small stones piled on top of mud, so even a light rain could render them impassable. A blind engineer named John Metcalf came up with a solution. He insisted that roads have a strong stone foundation. He "crowned" the roads too, meaning that he made them higher in the middle than on the sides. He added a ditch on either side, providing proper drainage to keep the roadways from caving in due to excess moisture. This also prevented potholes. But his methods proved costly and many local governments were loath to pay the construction costs. Undeterred, Metcalf challenged a colonel to race him to London. Thanks to the lousy road conditions, he made it to the city on foot faster than the colonel could get there in his horse-drawn buggy. As a result, towns across England began adopting Metcalf's engineering ideas. Even today, many of these ideas are still in use not only in England but around the world. What is the main idea of the passage?


A) Metcalf revolutionized road building in England.
B) Toll roads spread across England in the 1700s.
C) Roads were made with small stones piled on mud.
D) Metcalf raced a man in a horse and buggy and won.

Tidal Power The gravitational pull of the moon and the sun, as well as Earth's rotation, create the tides-the rise and fall in sea levels. In some places, tidal action can cause water levels-especially those near the shore-to vary up to forty feet. Today, the awesome power of the tides is used to generate electricity. The two main types of tidal power systems are tidal barrages and tidal turbines. Tidal barrages use a structure similar to a dam. The structure, called a barrage, is located across an inlet of an ocean bay or lagoon. Massive gates attached to the barrage open and close to control water levels and flow rates. They allow the tidal basin to fill with water on the incoming flood current. This water is then emptied through an electric turbine system on the outgoing current. As water races through the turbine system, electricity is generated. Tidal turbines look and operate quite similar to wind turbines, but because water is about 800 times denser than air, tidal turbines must be much sturdier and heavier. These power generation units are permanently attached to the sea floor in areas with a strong tidal flow. They operate as the ocean's current spins past massive blades. The blades are attached to turbines that produce electricity. Systems in Scotland and South Korea have tidal turbines that are capable of producing up to 1.5 megawatts of electricity-enough electricity to power roughly 1,500 homes. But tidal power is not without some drawbacks. Scientists think that the electromagnetic waves generated by the tidal turbines could disrupt ocean life. In particular, scientists are worried that they might affect the migration patterns of aquatic animals. But already, a workaround has been suggested-the turbines are simply turned off when certain migrating sea mammals approach them. Another drawback of tidal power is the high cost of construction. They are, for example, much more expensive to install than wind or solar power facilities. Still, tidal power facilities are durable, lasting as much as four times as long as wind or solar power plants. Tidal power emits zero greenhouse gases, so it is an extremely clean power source. It takes up relatively little space, too, when compared to other green energy projects. For example, the Sihwa Lake Tidal Power Station in South Korea was easily added to an existing 12.5 kilometer-long seawall. Windfarms and even solar farms, on the other hand, can take up vast tracts of land, sometimes amounting to hundreds of square kilometers. Another benefit of tidal power is that the power it generates is extremely predictable. Obviously, the gravitational pull of the sun and moon are not going to cease any time soon. The benefits of tidal power seem to outweigh its drawbacks. Clearly, it's time to produce more of these electricity-generating facilities wherever possible. Still, tidal power facilities are durable, lasting as much as four times as long as wind or solar power plants. What is the author's purpose in the following sentence (above) from the fourth paragraph of the passage?


A) To make a point that tidal power is less expensive to produce than other sources of electricity.
B) To stress that tidal power can be used in conjunction with solar and wind power sources
C) To offer a counterpoint to an earlier statement about the high cost of tidal power
D) To suggest that tidal power can be produced more efficiently than other alternative sources of power
