Glass
I wonder who first discovered glass. This commodity has been a part of civilization from the very beginning. Imagine a world without glass! How dark and dismal it would be. No windows, corrective lenses, telescopes, microscopes, cameras, sparkly drinking containers or mirrors. Life would not be the same without this wonderful discovery. Thank you, whoever found glass!
Glass is not an element, but a combination of several elements. It is a hard, brittle, transparent solid material composed mainly of silica, with additives to change the character of the glass. Common additives are soda, lime, lead, and boron. Each additive changes the properties of the final product. Soda and lime are the most common additives, accounting for about 90% of glass production. Adding lead increases reflectivity, causing the glass to "sparkle." The addition of boron changes the thermal and electrical properties of glass, allowing cookware that can be used in the oven without shattering.

The federal government regulates dietary supplements through the United States Food and Drug Administration (FDA). The regulations for dietary supplements are not the same as those for prescription or over-the-counter drugs. In general, the regulations for dietary supplements are less strict. To begin with, a manufacturer does not have to prove the safety and effectiveness of a dietary supplement before it is marketed. A manufacturer is permitted to say that a dietary supplement addresses a nutrient deficiency, supports health, or is linked to a particular body function (such as immunity) if there is research to support the claim. Such a claim must be followed by the words, “This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.†Also, manufacturers are expected to follow certain good manufacturing practices (GMPs) to ensure that dietary supplements are processed consistently and meet quality standards. Requirements for GMPs went into effect in 2008 for large manufacturers and are being phased in for small manufacturers through 2010. Once a dietary supplement is on the market, the FDA monitors safety and product information, such as label claims and package inserts. If it finds a product to be unsafe, it can take action against the manufacturer and/or distributor and may issue a warning or require that the product be removed from the marketplace. The Federal Trade Commission (FTC) is responsible for regulating product advertising; it requires that all information be truthful and not misleading. The federal government has taken legal action against a number of dietary supplement promoters or websites that promote or sell dietary supplements because they have made false or deceptive statements about their products or because marketed products have proven to be unsafe.
What is the meaning of the phrase 'phased in' as it is used in the third paragraph?
- A. stunned into silence
- B. confused
- C. implemented in stages
- D. legalized
Correct Answer: C
Rationale: The phrase 'phased in' refers to implementing something gradually or in stages. In the context provided, it means that the requirements for GMPs were gradually introduced for small manufacturers over a period of time. This approach allows for a structured implementation of the regulations, ensuring that small manufacturers have time to comply with the new standards.
Cystic fibrosis is a disease that is passed down through families. It is caused by a defective gene
that makes the body produce abnormally thick and sticky fluid, called mucus. This mucus builds
up in the breathing passages of the lungs and in the pancreas. The buildup of mucus results in
life-threatening lung infections and serious digestion problems. The disease may also affect the
sweat glands and a man's reproductive system. Millions of Americans carry a CF gene, but do
not have symptoms. This is because a person with CF must inherit two defective genes, one from
each parent. About 1 in 29 Caucasian Americans have the CF gene. It is more common among
those of northern or central European descent. Most children with CF are diagnosed by age 2.
For a small number, the disease is not detected until age 18 or older. These children often have a
milder form of the disease.
Which of the following describes the purpose of the passage?
A. To describe the causes of cystic fibrosis
B. To explain how cystic fibrosis is passed down through families
C. To overview the causes of CF and how it is carried
D. To review why some Americans have CF, but others do not
Which of the following groups is most likely to carry the cystic fibrosis (CF) gene?
- A. African Americans
- B. Asian Americans
- C. Caucasian Americans
- D. Native Americans
Correct Answer: C
Rationale: Cystic fibrosis (CF) is more common among those of northern or central European descent, making Caucasian Americans most likely to carry the CF gene. The passage mentions that about 1 in 29 Caucasian Americans have the CF gene. While individuals of any ethnic background can carry the CF gene, it is more prevalent in Caucasian populations, as stated in the passage.
The ebb and flow of laughter and silence fills the room as four old friends gather to engage in a
round of Bridge playing. For the beginner, Bridge can be complicated, but with time, effort, and a good teacher, even the novice can become proficient. Composed of two main parts, bidding and playing, Bridge requires the player's undivided attention. The dealer deals the entire deck of playing cards evenly between the for players, with
each person receiving thirteen cards. In the bidding portion of the game, the four suits of cards in the deck are ranked highest to lowest as follows: spades, hearts, diamonds, and finally clubs. However, during play all the suits of cards are
considered equals, and they go from highest to lowest from the ace being high to the two cards
being low. The highest number of tricks wins. A trick is one card played by each player for a
total of four. After the lead player lays down his/her card, the other players follow suit, if
possible. The highest card within the four "same suit" cards played wins the trick and picks up all
four cards. If a player cannot follow suit, he/she plays any card, but to make the game more
interesting and challenging, one suit is named a trump suit which means that if a player plays a
card from the trump suit, it always wins the trick. If two cards from the trump suit are played, the
highest card within the trump suit wins the trick. Obviously, the team with the most tricks wins
the hand.
In the passage, a trick is described as
- A. A special look given to your partner across the table
- B. A book that gives strategies on how to win at Bridge
- C. A collection of one card played by each of the four players
- D. A specific card the dealer gives to the person to her right
Correct Answer: C
Rationale: In the passage, a trick is defined as a collection of one card played by each of the four players. During gameplay, each player plays one card, and the highest card of the same suit wins the trick. The team with the most tricks wins the hand. Understanding what constitutes a trick is essential in mastering the game of Bridge. It is crucial for players to grasp the concept of a trick to strategize their gameplay effectively and aim to win as many tricks as possible to secure victory in the game.
Centuries ago, in the country of Siam, now known as Thailand, it was the custom of the rulers
that displeased them by giving the offender a white elephant. Because the animal was could not
be made to work as other elephants did, but still had to be fed hundreds of pounds of fruit and cared for in the most lavish style. The recipient could not give the elephant to anyone else, as it was the ruler, who would be greatly displeased should the recipient not receive the gift graciously or care for in a grand style. This monetary burden could be a major liability to the
recipient and in many cases they became impoverished.
This is the origin of the term "white elephant" as it is used today to denote an unwanted gift. The way of gift exchange played during the holiday season is an offshoot of this. In this game, everyone brings, and the gifts are exchanged by drawing numbers and picking a gift in turn. The
second person can choose or steal the first one. It is all in good fun, and people enjoy giving silly
gifts and "stealing" someone else.
In which continent is Thailand located?
- A. Africa
- B. Europe
- C. Asia
- D. South America
Correct Answer: C
Rationale: Thailand is located in Asia, not Africa, Europe, or South America. It was formerly known as Siam before being renamed. The country has a rich history and cultural heritage. Understanding basic geography helps in broadening knowledge about different countries and regions. Knowing the location of countries is essential for various purposes, including travel, trade, and cultural understanding.
Over the last few decades, medical experts have changed their thinking on the health effects of some common foods and beverages. Higher-fat foods and some alcoholic beverages like red wine and beer, once viewed as top threats to a healthy lifestyle, are now seen by many as less harmful and even as having some health benefits. But there is perhaps no topic that the medical community has reversed its
thinking on more often than coffee. Since long before the advent of modern medicine, public opinion regarding the health effects of coffee has been diverse and ever-changing. Opinion on coffee's health effects can be traced back several centuries. In the 1600s, doctors in England touted coffee as a cure for alcoholism, but some women complained that coffee was making their husbands impotent. They may have been correct, as caffeine is a
diuretic and can irritate the prostate (dehydration and prostatitis can both lead to erectile dysfunction). In the late 1700s, coffeehouses began opening all over colonial America, where coffee was seen as a healthy stimulant that helped the colonists work longer hours. But by the early 1900s, public concern grew as coffee consumption was blamed for a variety of common ailments, such as nervousness, indigestion, and insomnia. In the 1970s, medical journals published studies that linked coffee consumption with high blood pressure and an increased risk of heart attacks. In 2001, a meta-study indicated that coffee was responsible for a 20% increase in risk for urinary tract cancer. But starting in 2007, to the surprise of many, meta-studies began to show positive health effects of coffee consumption. A 2007 study showed that coffee was viewed by many as "practically a health food." However, CNN also warned that given the long history of flip-flops on the health effects of coffee, medical and public opinion on coffee could easily turn negative again.
