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.
Based on this passage, what can the reader infer about the advice physicians will give their pregnant patients about coffee consumption?
- A. Almost all of them will advise women to stop drinking any caffeine until after the baby is born.
- B. The majority will ignore the study altogether and continue to advise caffeine in moderation as before.
- C. All of them will demand additional research be done before they change what they tell their patients.
- D. Some will continue to make their normal recommendations about caffeine, while others will be more cautious than before.
Correct Answer: D
Rationale: The inference is that some physicians will continue with their usual recommendations while others may become more cautious.

Modern PE Classes:
In some schools around the country, physical education classes look a lot different than they did a generation or two ago. Kids are still in motion, stretching, running, lifting, and sweating. But instead of everyone doing the same activity at the same time as a team, they are exercising independently. They are being taught movements and activities that their teachers hope they will incorporate into their lives rather than just perform long enough to get a good grade.
By teaching kids the pleasure of exercise, gym teachers hope to instill important lessons about maintaining good health, staying fit, and keeping weight under control. Students can also participate in low-impact sports like yoga, martial arts, and weight lifting. Instead of playing basketball or baseball, they can focus on more general skills like passing the ball.
A growing number of physical education (PE) teachers are also putting more of an emphasis on general nutrition and health. With the continual increase in the number of children who are obese, there is greater pressure to teach students how to stay fit. To do this, gym teachers have to look at new ways to introduce exercise to their students that will not intimidate or overwhelm them but instead intrigue and engage them.
One other difference found in some modern gym classes is the grading system. Instead of being graded on their ability to run laps in a set time or make a certain number of baskets, the students are graded simply on the effort they make in the class. Some even get extra credit if they are the sweatiest students in the room!
What would be the best title for this passage?
- A. Being a Team in PE
- B. A New Kind of Grade
- C. Learning Martial Arts
- D. PE for School and Life
Correct Answer: D
Rationale: The best title for this passage is 'PE for School and Life' as it encapsulates the broader purpose of physical education described in the extract. The passage emphasizes teaching students lifelong fitness habits, instilling lessons about maintaining good health, staying fit, and introducing exercise that can be incorporated into their lives. The focus is on fitness as a lifelong skill rather than just a short-term activity for a good grade.
Choice A, 'Being a Team in PE,' is incorrect as the passage highlights individual exercise and movement rather than team-based activities. Choice B, 'A New Kind of Grade,' is also incorrect as the passage mentions a shift in grading towards effort rather than specific performance tasks. Choice C, 'Learning Martial Arts,' is too narrow as the passage discusses a variety of activities beyond martial arts that are taught in modern PE classes.
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
Correct Answer: D
Rationale: The author's tone is disapproving, as evidenced by the focus on the negative consequences of using cosmetics with harmful ingredients. The passage discusses historical and contemporary health issues related to beauty practices, indicating a critical stance on the use of cosmetics that compromise health, which supports option D.
THE FOOD PYRAMID:
The food pyramid is a visual representation of how the different food groups can be combined to form a healthy diet. Although it was a vital part of dietary guidelines for years before being replaced by the �MyPlate� model, the pyramid was constantly analyzed and revised as additional study was done in nutritional fields. A few years ago, the pyramid underwent a change regarding the unique dietary needs of seniors.
Modifications in the pyramid for older adults included an emphasis on fiber and calcium, as well as on vitamins D and B12. By incorporating these changes, the pyramid indicated that the nutrients found in a person�s routine daily consumption typically are not enough for seniors. Seniors need supplementation. As people age, they tend to move less and thus need fewer calories to maintain their weight. Because seniors tend to eat a more limited amount, dietitians urge them to choose wisely. They are encouraged to eat nutrient-rich meals featuring such foods as fruits, vegetables, low-fat dairy products, and high-fiber whole grains.
The revised pyramid also focused on the importance for older people of ingesting adequate amounts of fluids daily. This helps to ensure proper digestion and prevent dehydration. Finally, the revised pyramid included information on incorporating exercise and other physical activities into the lives of older adults. Suggestions included swimming, walking, or simple yard work. With recent reports indicating that obesity levels for people older than 70 years of age are climbing, performing some type of regular exercise is more essential than ever.
Which of the following is not mentioned as being important for seniors?
- A. Vitamin B12
- B. Calcium
- C. Nitrates
- D. Exercise
Correct Answer: C
Rationale: The passage lists important nutrients for seniors, including fiber, calcium, vitamin D, and B12, while exercise is also discussed as crucial for health. However, nitrates are not mentioned at all, making option C correct since it stands out as the only nutrient not discussed in the context of seniors' health

What is the meaning of the word instill as used in the second paragraph of the passage?
- A. Impart
- B. Propagandize
- C. Demand
- D. Create
Correct Answer: A
Rationale: The correct answer is A: 'Impart.' In the context of the passage, 'instill' means to impart important lessons about maintaining good health, staying fit, and keeping weight under control. This word choice is appropriate as it aligns with the idea of teaching and passing on knowledge. Choice B, 'Propagandize,' is incorrect as it implies spreading biased or misleading information, which is not the intended meaning in this context. Choice C, 'Demand,' is incorrect as it does not capture the concept of teaching or passing on lessons. Choice D, 'Create,' is also incorrect as it does not convey the idea of imparting knowledge or lessons, which is the central meaning of 'instill' in this context.
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.
