SUNLIGHT:
Most people are familiar with the damaging effects of the sun on unprotected skin, but not enough attention is paid to the many positive effects of receiving direct exposure to sunlight on a regular basis. The most compelling argument for increased exposure to sunlight is the need for vitamin D in the human body. Vitamin D is integral for maintaining healthy bones and preventing diseases like rickets and osteoporosis. It is synthesized by the skin when it comes into contact with the UVB rays found in sunlight. In order to ensure you are receiving the proper amount of vitamin D, it is recommended to get 15 minutes of direct exposure to sunlight at least two or three times a week. UVB rays are made less intense when passing through clouds and pollution, and they will not transmit through glass or sunscreen. UVB rays are also less effective the farther you are from the equator. People with darker skin require more exposure to the sun to receive the same amount of vitamin D.
In addition to vitamin D, sunlight will help regulate the circadian rhythms that ensure you get a good night’s sleep. Sunlight helps to prevent an overactive immune system, which may prove useful in preventing autoimmune diseases like psoriasis and lupus. Recent studies have even shown that sunlight can help lessen the symptoms of Alzheimer’s disease. The negative impacts of excess exposure to sunlight should not be ignored; cancers resulting from skin damage are a real concern that must be taken seriously. But the importance of vitamin D and the other positive impacts of sunlight make a compelling argument for making sure we are spending enough time every week in direct sunlight.

Barefoot Running:
Barefoot running is a rapidly growing movement that encourages people to leave their shoes at home and take to the streets in only their bare feet. Barefoot running advocates are quick to point out that while shoe technology has advanced significantly since the advent of the modern running shoe, there has been little decline in the number of injuries that occur from running. Humankind has been running for millions of years, and modern running shoes have existed for less than 50 years. By wearing larger shoes with excessive cushioning, we are changing the biomechanics of how we run, thereby increasing the likelihood for injury.
Early humans ran with a “forefoot strike,” landing closer to the balls of their feet and using their foot’s natural arch as a spring to store and release energy. Modern shoe designs encourage a “heel strike,” landing on the heel and rolling forward to the toe. Barefoot running advocates believe “heel striking” replaces your reliance on the natural mechanics of your feet with the cushioning provided by your shoes, and that this is what causes many of the injuries affecting runners today.
Critics assert that while our feet may have been designed for barefoot running, our road surfaces were not. Concrete and asphalt are much firmer than any surface where our human ancestors would have been running. Broken glass and debris also may make barefoot running a significant challenge. There is little consensus when it comes to the safety and effectiveness of barefoot running, but even the most skeptical of podiatrists will agree that wearing heavily padded shoes too often can result in a weaker foot and leg structure. Spend some extra time walking barefoot around your house; aside from building up the muscles and tendons that strengthen your feet, you may just find yourself tempted to go for a run.
What is the meaning of the word consensus as it is used in the last paragraph about Barefoot Running?
- A. Investigation.
- B. Purpose.
- C. Trepidation.
- D. Unanimity.
Correct Answer: D
Rationale: Consensus in this context refers to unanimity, meaning a general agreement among people.
Aromatherapy:
For years, aromatherapy has been touted as a safe and natural way to relax and even heal. Essential oils from a variety of scents have been added to candles and sprays to help people feel better. However, a recent study performed at Ohio State University says that these smells, as nice as they may be, do not do a thing to improve people’s health.
To find out if aromatherapy actually works, the researchers tested two of the most popular scents: lemon and lavender. First, test subjects had their heart rate, blood pressure, stress hormones, and immune function measured and noted. Next, they were subjected to mild stressors and then told to sniff one of the scents to see if the scent would help them to relax. Finally, all the subjects were tested again to look for improvement. No significant changes were noted—even in people who had previously stated they were true believers in the power of aromatherapy.
Of course, this does not necessarily prove that aromatherapy is worthless, either. It was just one small study, pitted against the opinions of thousands of consumers who swear by peppermint on their pillow for an upset stomach or vanilla for a headache. More tests will be done, but in the meantime, a whiff of lavender, lemon, or other scents will certainly do no harm—and can be quite pleasant at the same time.
Which of the following is not listed as a detail in the passage about Aromatherapy?
- A. Subjects were given mild stressors.
- B. Lemon and lavender scents were tested.
- C. Vanilla worked better than lemon for stress.
- D. The study took place at Ohio State University.
Correct Answer: C
Rationale: The passage does not mention vanilla working better than lemon for stress relief.

SUPER FOODS:
Super foods are whole, unprocessed foods such as blueberries, walnuts, beans, oats, and broccoli. Spinach, yogurt, and pomegranates are also considered super foods. They are classified as such because they contain high levels of essential nutrients, are low in calories, and can often help prevent—and even reverse—some of the common effects of aging including cardiovascular disease, type 2 diabetes, high blood pressure, and certain types of cancer. Super foods help lower cholesterol levels in the blood and, some researchers believe, even improve a person’s mood.
High on the list of super foods are blueberries, fresh or frozen, which are loaded with vitamin C, antioxidants, and potassium. Blueberries are also an anti-inflammatory, which many researchers and nutritionists believe is beneficial. Lentils are a super food that helps prevent a spike in insulin levels that can increase body fat. Lentils are high in both fiber and protein, each of which contributes to stabilizing blood sugar levels and reducing excess fat, especially in the stomach area. Walnuts are a plant-based source of essential unsaturated omega-3 fatty acids, which can improve cholesterol and lower the risk of heart disease by as much as 50 percent.
All oats are healthful. Oats, even instant oatmeal, are digested slowly while providing up to five grams of fiber per serving. As physicians and nutritionists continue to study super foods and their effects, consumers continue to educate themselves about the variety of benefits. In an era when consumers question the origin and nutritional value of much of the food on store shelves, super foods are some of the most healthful and natural whole foods available.
Which of the following statements is an opinion related to Super Foods?
- A. Walnuts contain omega-3 fatty acids.
- B. Lentils are high in both protein and fiber.
- C. Pomegranates are delicious and healthful.
- D. Oats move slowly through the digestive tract.
Correct Answer: C
Rationale: This is an opinion because it is a subjective statement about taste.
Sickle-Cell Anemia:
Healthy red blood cells are shaped like a disc. Each cell contains the protein hemoglobin, which carries oxygen throughout the body. In some people, a crescent-shaped cell forms instead of the normal disc-shaped cell. The crescent-shaped cells contain abnormal hemoglobin. These sickle-shaped cells are fragile and are unable to carry oxygen properly throughout the body.
Sickle-cell anemia is an inherited disease that affects about 72,000 people in the United States. It is more common among people of South American or African descent. The genes for sickle-cell anemia are inherited from both parents. When both parents carry a gene for the trait for sickle-cell, there is a one in four chance that they will pass the disease on to their children.
Symptoms of sickle-cell anemia can include sudden occurrences of extreme abdominal and back pain, bone pain, fever, fatigue, and a rapid heart rate. One patient compared the pain in his back to a jackhammer and said the pain could take over his entire body. Another patient, an eight-year-old girl, described fevers and the feeling of someone squeezing her arms and legs. Cycles of symptoms are often unpredictable and can occur infrequently or almost constantly. Some people who are affected report weekly occurrences of persistent pain, while others report occurrences once a month. Some report that relief comes only by using powerful painkillers. For others, relief comes with bed rest and a hot-water bottle. Most agree that while the challenges of managing sickle-cell anemia are great, with diligent care, it can be managed.
What is the overall tone of the essay?
- A. Informative
- B. Insensitive
- C. Grim
- D. Uplifting
Correct Answer: C
Rationale: The passage discusses the challenges and symptoms associated with sickle-cell anemia, portraying a somber and serious tone. The descriptions of persistent pain, difficulties, and the impact on individuals' lives make the overall tone fairly grim. The essay focuses on the hardships faced by individuals with sickle-cell anemia, highlighting the severity of the disease. Choices A, B, and D are incorrect because the tone of the essay is not informal, insensitive, or uplifting. It is important to consider the language used, the subject matter, and the overall emotional impact of the text to determine the tone accurately.
