MRSA:
Methicillin-resistant Staphylococcus aureus (MRSA) is a form of the Staphylococcus aureus bacterium that is resistant to antibiotics and, as a result, is very difficult to treat. MRSA now kills more Americans every year than HIV/AIDS, and the rates of infection are rising. Methicillin, an antibiotic introduced in the 1960s, was intended to combat Staphylococcus aureus, which is ubiquitous in hospitals. However, within a year of its introduction, doctors began finding strains of bacteria that had already developed immunity to methicillin. By the 1990s, MRSA had become the leading hospital-acquired skin infection in the United States.
At the same time MRSA started appearing outside of hospitals, different strains of the bacteria emerged, spreading just as quickly and being just as dangerous. In the past 15 years, MRSA bacteria have become ubiquitous not only in hospitals but also in gyms, locker rooms, swimming pools, and other settings with frequent human contact.
Researchers in Ireland are developing technology that may significantly halt the spread of hospital-associated MRSA bacteria. They have created a textile made of nanomaterials 1,000 times smaller than a human hair. These textiles have been shown to halt the spread of infection and can be used for linens, drapes, and upholstery in hospitals. The potential for this technology to reduce instances of hospital-associated MRSA is staggering.
To reduce your risk of community-associated MRSA infection, regularly wash your hands, cover all open wounds with a clean bandage, and avoid sharing personal items like razors or towels.

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

  • A. Hospitals may soon limit the spread of infection with a new textile.
  • B. MRSA begins by infecting the skin.
  • C. You are most likely to contract MRSA in a crowded location.
  • D. Used clothing stores may harbor MRSA.
Correct Answer: D

Rationale: The correct answer is D: 'Used clothing stores may harbor MRSA.' This statement is not supported by the passage. The passage mentions the spread of MRSA in hospitals, gyms, locker rooms, swimming pools, and other settings with frequent human contact, but it does not mention used clothing stores as a common location for MRSA. Therefore, it is an unlikely inference. Choice A is supported by the passage as it discusses the development of a new textile to halt the spread of hospital-associated MRSA. Choice B is also supported as the passage mentions MRSA as a skin infection. Choice C is supported by the passage as it states that MRSA has become ubiquitous in settings with frequent human contact.

FAT IN A HEALTHY DIET:
After years of bad publicity, it may sound absurd, but many dietitians are now extolling the virtues of consuming fat. According to Laurie Tansman, a nutritionist at Mt. Sinai Medical Center in New York, fat "not only plays a vital role in the health of the membrane of every cell in our body, it also helps protect us from a number of key health threats." Fat is a critical part of your necessary food intake, with a general recommendation that 30 percent of your daily calories should come from fat. Without it, your body would not be able to absorb or transport vitamins A, D, E, and K. Additionally, body temperature, hair follicles, and skin cells all rely on the consumption of fats to function properly.
There is near-universal agreement that the healthiest fats are unsaturated fats. This category includes olive oil, sesame oil, walnut oil, avocado oil, and omega-3 fatty acids. When consumed in moderation, these fats can lower cholesterol levels, thereby reducing the risk of heart disease. Saturated fats, while not as healthy as unsaturated fats, should still be consumed more sparingly. These fats are commonly found in animal products such as beef, pork, and chicken.
The least healthy of all fats are trans-fatty acids, or trans fats. Though trans fats can occur naturally in small amounts in animal products, they are more commonly found as artificially produced oils used for frying foods or softening prepackaged snacks. These fats increase the risk of heart disease, and the U.S. Dietary Guidelines recommend consuming as few trans fats as possible.

What conclusion can a reader draw from this passage?

  • A. It is advisable to choose unsaturated fats over saturated fats.
  • B. Saturated fats are more calorically dense than unsaturated fats.
  • C. Trans fats are more calorically dense than saturated fats.
  • D. Unsaturated fats are mostly found in animal products.
Correct Answer: A

Rationale: The correct conclusion that can be drawn from the passage is that it is advisable to choose unsaturated fats over saturated fats. The passage emphasizes the health benefits of unsaturated fats, such as lowering cholesterol levels and reducing the risk of heart disease. It also mentions that saturated fats, although not as healthy as unsaturated fats, should still be consumed sparingly. Trans fats are highlighted as the least healthy fats, increasing the risk of heart disease. Choice B is incorrect because the passage does not explicitly compare the caloric density of saturated and unsaturated fats. Choice C is incorrect as the passage does not discuss the caloric density of trans fats in comparison to saturated fats. Choice D is incorrect as the passage states that unsaturated fats are found in sources like olive oil, walnut oil, and avocado oil, not mostly in animal products.

Life Expectancy in the US:
Where would you expect the United States to rank in life expectancy, the average number of years a person is expected to live? Near the top in the world, right? Well, surprise—we rank number 31, after Costa Rica and right before Cuba. World Health Organization data from 2015 indicate that the average life expectancy worldwide is 71 years—slightly more for females and slightly less for males. In the United States, we beat that average by around eight years. Yet we are several years behind Japan, with a female life expectancy of 86.8 years, or Switzerland, with a male life expectancy of 81.3 years. Even relatively poor European countries, such as Slovenia, Cyprus, and Malta, do better than we do.
There are a number of indicators that lead to our low score among wealthy nations. Those include obesity and its accompanying heart disease and diabetes, car crash deaths, gun violence, and embarrassingly high infant mortality rates. We eat more, drive more, have more guns, and allow poor women to go through pregnancies unattended by regular physicians. There are many other health indicators that separate us from other developed nations, but most correspond to the extreme wealth inequities in the United States.
It is too soon to tell whether an increase in insured Americans will help to turn this distasteful data around. Certainly those nations with universal health care have better numbers than we do. Much of our problem has to do with lifestyles that will not be easy to alter. We continue to build living spaces that are not walkable, to work long hours and drive long distances, to overeat—and we love our Second Amendment right to bear arms. It is difficult to imagine how we will overcome these realities and improve our longevity status.

What is the overall tone of the essay?

  • A. Apathetic
  • B. Fascinated
  • C. Discouraged
  • D. Hopeful
Correct Answer: C

Rationale: The tone of the essay is discouraged as it expresses concern about the U.S.'s lower life expectancy ranking and contributing factors.

ACUPUNCTURE:
Over the years, acupuncture has become a more widely accepted type of alternative medicine. It is used for a wide variety of ailments, and if a recent study from Germany is valid, relieving menstrual pain can be added to the continuously growing list.
Traditionally nonsteroidal anti-inflammatory drugs (NSAIDs) are the typical treatment for menstrual discomfort. However, as many consumers and physicians are aware, NSAIDs have a number of side effects, including nausea, vomiting, rash, dizziness, headache, and drowsiness. Acupuncture rarely has any kind of side effects other than the occasional stinging sensation when the needle is inserted or a deep ache around it after it is in place.
Acupuncture has proven helpful with relieving a number of kinds of pain, so researchers at Charité University Medical Center in Berlin wanted to find out how effective it might be in combating cramps and other menstrual discomforts. More than 200 women were enrolled in the study, and after three months and approximately 10 sessions, the women who were treated with acupuncture reported significantly less pain than those in the control group who received no treatment at all. They also reported a 33 percent improvement in their symptoms.
Because of these findings, the researchers came to the conclusion that “acupuncture should be considered as a viable option in the management of these patients.”

What is the meaning of the word viable as used in the last paragraph?

  • A. Reasonable
  • B. Unresolved
  • C. Contemporary
  • D. Consistent
Correct Answer: A

Rationale: Viable in this context means reasonable, referring to acupuncture as a valid treatment option.

Lifewings Partners:
What do pilots, astronauts, physicians, and risk managers have in common? In this case, they are all part of Lifewings Partners, an organization based in Memphis, Tennessee, dedicated to eliminating mistakes and accidents in medical settings across the United States.
Lifewings Partners highlights the need for vigilance in medical environments. According to the Institute of Health, approximately 98,000 patients die each year in U.S. healthcare settings due to medical errors. Examples of such errors include a man who had the wrong testicle removed in a Los Angeles hospital, a young boy who suffered brain damage from anesthesia during a routine hernia surgery, and a hospital in Rhode Island that performed brain surgery on the wrong side of the brain on three different patients in less than a year.
To combat these issues, Lifewings Partners not only advocates for internal changes in medical procedures and the establishment of checklists but also focuses on patient education. They recommend that consumers research a hospital’s safety record online, discuss safety standards with their doctors, and inquire about facilities with the best safety records.
Founder Steve Harden emphasizes, “Just because a hospital has a great reputation for cutting-edge medicine doesn’t necessarily mean the hospital is the safest place to go for routine procedures.” He warns that some mistakes are too significant and irreversible to risk, underscoring the importance of careful selection and preparation in healthcare settings.

Which statement about Lifewings Partners is a fact?

  • A. Everyone should have access to Lifewings.
  • B. The people in Lifewings are modern heroes.
  • C. Steve Harden was clever to found Lifewings.
  • D. Lifewings is based in Memphis, Tennessee.
Correct Answer: D

Rationale: The statement that Lifewings is based in Memphis, Tennessee, is a verifiable fact.

Choose the best summary of the passage.

  • A. We often think of all fat as bad, but it is clear that certain fats, especially the more healthful unsaturated fats, are important for bodily function.
  • B. If you must consume some fat, be sure to choose unsaturated fats such as oils rather than saturated fats found in prepackaged snacks or animal products.
  • C. Doctors and researchers have discovered that without the calories found in fat, people would not have functioning metabolisms.
  • D. Some intake of saturated fat is necessary, but you should stay away from the kind of fat found in fried food, which can lead to heart disease.
Correct Answer: A

Rationale: The best summary of the passage emphasizes the importance of certain fats, particularly unsaturated fats, for bodily function. It highlights that after years of negative publicity, experts now recognize the significance of consuming fats for overall health. The passage discusses how fat is essential for cell health, vitamin absorption, and various bodily functions. It also distinguishes between healthier unsaturated fats like olive oil and detrimental trans fats. Choice B is not the best summary as it focuses more on the choice between unsaturated and saturated fats rather than the overall importance of fats. Choice C is incorrect as the passage doesn't solely attribute functioning metabolisms to fat calories. Choice D is not the best summary as it only briefly mentions saturated fats and fried foods, missing the broader context provided in the passage.
