Evolution of the CDC:
The Centers for Disease Control and Prevention (CDC) started in 1946 as the Communicable Disease Center (CDC). Its original goal was to stop malaria in the United States. From a small office in Atlanta, health workers spread out over the South, spraying mosquitoes and using shovels to eliminate low spots of standing water. At that time, most of the CDC’s workers were not doctors; the need was for entomologists and engineers. The founder of the CDC, Dr. Joseph Mountin, enlarged the organization’s mission to fight communicable diseases of all kinds, and over the next 20 years, the CDC would focus on smallpox, measles, and polio.
In 1970, the name was changed to the Center for Disease Control, but the mission continued to expand. By 1980, the CDC was working not only on the eradication of existing diseases but also on disease prevention. By this point, it had hundreds of doctors and researchers looking into health problems such as depression and addiction. The name changed again, to the Centers for Disease Control and Prevention. Today, the CDC has thousands of employees and coordinates research activities with public health agencies worldwide. It is especially known for its work to protect people from epidemics and unexpected health threats, but its everyday work in the areas of environmental health, injury prevention, birth defects, healthy schools and workplaces, and health education is just as important and beneficial to all Americans.

What is the overall tone of the essay about A Short History of the CDC?

• A. Appreciative.
• B. Awestruck.
• C. Somber.
• D. Disheartened.

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.

The passage mentions all of the following claims for the health benefits of super foods EXCEPT ___________.

• A. lowering cholesterol
• B. stabilizing insulin levels
• C. building muscle mass
• D. reducing blood pressure

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.

Which statement would not be inferred by the reader in the passage about Barefoot Running?

• A. Runners who take their shoes off may face some hazards.
• B. Modern running shoes may increase the odds for injury.
• C. Walking barefoot is good for the muscles and tendons.
• D. Before 1950, even Olympic runners ran barefoot.

YOGA:
Yoga is an exercise that everyone should try. Yoga was first practiced thousands of years ago. It helps connect the mind and body by taking a person through a series of poses while emphasizing controlled breathing and meditation.

Every year hundreds of thousands of people enjoy the benefits of yoga by treating the movements and postures as exercise. Yoga works by safely stretching muscles, ligaments, and tendons. This helps release the buildup of lactic acid in the muscles that can often cause stiffness, tension, and even pain. Yoga helps develop the body’s range of mobility and increases the ease of everyday movements. Many participants report improved flexibility, especially in the trunk and shoulders, after only two months of practice.
Yoga improves posture, balance, and sleep, and it also helps with weight control. Physically, many yoga poses help build upper-body strength, which is increasingly important as the body ages. Other poses help strengthen the muscles in the lower back, and when properly practiced, nearly all of the poses strengthen the body’s abdominal, or core, muscles. This helps improve the circulation of blood that increases the delivery of nutrients and oxygen to the body and also removes wastes produced by the body. When combined with yoga’s benefit of lowering a person’s heart rate, the result is increased cardiovascular endurance.
The University of Maryland School of Nursing recently published a study that showed yoga was especially effective at reducing stress. In addition, researchers found that yoga surpassed traditional aerobic exercise, often significantly, in improving flexibility, pain tolerance, and daily energy levels. One enthusiast says that her advice to skeptics is simple, “Take a deep breath, stretch, and indulge in a few poses. You’ll feel better.”

What is the meaning of the word tolerance as used in the last paragraph about Yoga?

• A. Open-mindedness.
• B. Approval.
• C. Endurance.
• D. Generosity.
