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.

A reader might infer from this passage that ___________.

• A. Obesity can be detrimental to a long life
• B. Car crashes are most frequent in the United States
• C. The Second Amendment should be overturned
• D. People in Asia and Africa have the shortest life spans

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 of the following is not listed as a detail in the passage?

• A. Many patients die each year from medical error.
• B. Lifewings Partners educates patients on consumer safety.
• C. Steve Harden is the founder of Lifewings Partners.
• D. The most common medical error is overmedication.

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.”

Which detail is not given as a side effect of NSAIDs?

• A. Nausea
• B. Headache
• C. Weight loss
• D. Dizziness

MICROBES IN HUMAN HEALTH:
There are 10 times more microbes than human cells in the human body. Scientists have long known that the human body hosts a staggering number of microorganisms. Recent discoveries, however, are shedding light on how pivotal these bacteria are in the development of the human immune system. The body supports a wide array of microorganisms specially adapted to survive in particular regions. Remarkably, there is such variation in these microorganisms that few people share the same strains in the same quantities.
The colonization of microbes begins at birth. A newborn infant, emerging from the germ-free environment of the womb, is immediately exposed to germs from its mother's birth canal. These bacteria swiftly begin to breed and colonize the infant's body, which becomes their new host. The most fascinating discovery is not just that the immune system tolerates these millions of harmless organisms, but that it may actually rely on their presence to function properly.
For example, laboratory mice unable to produce a specific inflammation-reducing molecule were injected with a particular strain of bacteria. After the bacteria colonized, the mice's immune systems developed the ability to synthesize the molecule. Essentially, the mice needed the bacteria for their immune systems to function correctly.
This concept is also being applied to humans through a relatively experimental procedure known as fecal bacteriotherapy. This treatment reintroduces healthy bacteria into a colon that has lost its ability to defend against pathogens. While scientists are only beginning to understand the critical role these microorganisms play in human health, early research has yielded remarkable discoveries.

What is the author's primary purpose in writing this essay about microbes?

• A. To persuade
• B. To inform
• C. To entertain
• D. To analyze

Coffee Consumption During Pregnancy:
The health risks of coffee have long been debated, but a recent study has added another argument against too much coffee consumption. This study looked at the effect of drinking coffee on pregnant women. Conducted by physicians at Kaiser Permanente, the study explored the connection between caffeine and the risk of miscarriage.
This study followed more than 1,000 women who became pregnant within a two-year period. The amount of caffeine they drank was logged, as well as which women experienced a miscarriage. The results, as published in the January 2008 issue of the American Journal of Obstetrics and Gynecology, stated that the risk of miscarriage more than doubled in women who consumed 200 mg or more of caffeine per day—about what is found in two cups of coffee.
Why does caffeine carry this risk? Researchers are not sure, but they theorize that the caffeine restricts blood flow to the placenta. This, in turn, can harm the developing fetus.
Does this mean the physicians will start advising women to quit drinking coffee while pregnant? Yes and no. Some doctors will certainly take this report to heart and encourage their patients to stay away from more than one cup of coffee a day, just as they recommend not drinking alcohol or smoking cigarettes. Others are not so convinced and doubt that this single study is enough to overturn the established guidelines of the American College of Obstetricians and Gynecologists. Instead, they believe that a lot more research needs to be done.

What is the meaning of the word overturn in the last paragraph of the passage?

• A. Justify
• B. Invalidate
• C. Support
• D. Review
