BEAUTY THE BEAST:
In recent years, there have been frightening headlines about harmful ingredients such as mercury and lead in ordinary cosmetics. However, these are hardly the first examples of people paying a heavy price to conform to cultural ideals of beauty. This tradition has been around for centuries.
Ancient Egyptians decorated their eyes with malachite (a green ore of copper), galena (a lead sulfide), and kohl (a paste made from soot, fat, and metals such as lead). While these cosmetics may have enhanced their appearance, they also led to health problems such as insomnia and mental confusion.
The ancient Greeks took these practices even further. They applied lead to their entire faces to clear their complexions and improve skin coloration. This practice resulted in health issues ranging from infertility to insanity. The lead ointment whitened their faces�a sign of beauty�while red lead was added to the cheeks for a rosy glow. To make matters worse, they also used hair dyes containing lead.
The Romans adopted these toxic beauty practices, and some historians suspect that lead poisoning contributed to the decline of the Roman Empire. As recently as 2007, lipsticks and mascaras were found to contain lead and mercury. Additionally, phthalates�industrial chemicals that can cause birth defects and infertility�are present in personal care products such as shampoos, lotions, perfumes, and deodorants.
An old saying states that beauty has a price, and sometimes that price may be much higher than consumers realize. It is important to be aware of what you are putting on your face.

What is the author's attitude toward the use of cosmetics?

• A. Sympathetic
• B. Mocking
• C. Tolerant
• D. Disapproving

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.

The word watchdog as used in the second paragraph of the passage can best be defined as ___________.

• A. companion
• B. guard
• C. manager
• D. punisher

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.

Choose the best summary of the passage about microbes.

• A. Scientists have discovered the importance of certain bacteria for a well-functioning immune system, especially in defending against pathogens. The colonization of microbes in the body begins at birth, with the immune system relying on these bacteria for proper function.
• B. The passage discusses the role of bacteria in the development of the human immune system. It highlights that the body supports various microorganisms crucial for immunity, starting from birth. The presence of harmless bacteria is essential for the immune system to work effectively.
• C. The body hosts a vast number of microorganisms critical for immune system development. Harmless bacteria are necessary for the immune system to defend against pathogens effectively. Early research shows promising results in fecal bacteriotherapy for restoring the immune system's ability to fight off harmful invaders.
• D. Microbes play a pivotal role in human health, particularly in immune system development. The introduction of healthy bacteria is essential for the immune system to function correctly. Fecal bacteriotherapy is a novel approach to reintroducing beneficial bacteria into a compromised colon to enhance immune response.

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.

What is the main idea of the passage about MRSA?

• A. Methicillin-resistant Staphylococcus aureus (MRSA) is a significant problem both within and outside of hospitals, and there are ways to mitigate the risk.
• B. A new textile made of nanomaterials could significantly reduce the spread of hospital-associated MRSA infections.
• C. There are multiple strains of MRSA, and they pose various risks beyond just fatality.
• D. MRSA is a significant problem both within and outside of hospitals, but there are ways to mitigate the risk.

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
