Read the following article and answer the question. Article: Many children first learn the value of money by receiving an allowance. The purpose is to let children learn from experience at an age when financial mistakes are not very costly. The amount of money that parents give to their children to spend as they wish differs from family to family. Timing is another consideration. Some children get a weekly allowance. Others get a monthly allowance. In any case, parents should make clear what, if anything, the child is expected to pay for with the money. At first, young children may spend all of their allowance soon after they receive it. If they do this, they will learn the hard way that spending must be done within a budget. Parents are usually advised not to offer more money until the next allowance. The object is to show young people that a budget demands choices between spending and saving. Older children may be responsible enough to save money for larger costs, like clothing or electronics. Allowances give children a chance to experience the things they can do with money. They can share it in the form of gifts or giving to a good cause. They can spend it by buying things they want. Or they can save and maybe even invest it. Saving helps children understand that costly goals require sacrifice: you have to cut costs and plan for the future. Requiring children to save part of their allowance can also open the door to future saving and investing. Many banks offer services to help children and teenagers learn about personal finance. A savings account is an excellent way to learn about the power of compound interest . That may not seem like a lot. But over time it adds up. Question: Why are parents advised not to offer young children more money in advance? Answer:
****

Read the following article and answer the question. Article: "In only six days I lost seven pounds of weight." "Two full inches in the first three days!" These are the kinds of statements used in magazine, newspaper, radio and television ads, promising new shapes and new looks to those who buy the medicine or the device (;). The promoters (;) of products say they can shape the legs, slim the face, smooth wrinkles, or in some other way to beauty or desirability. Often such products are nothing more than money--making things for their promoter. The results they produce are questionable, and some are dangerous to health. To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation . If the product is a drug, FDA(Food Drug Administration) can require proof under the Food, Drug, and Cosmetic Act that is safe and effective before it is put on the market . But if the product is a device, FDA. has no author to require premarketing proof of safety or effectiveness. If a product already on the marker is a danger to health, FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action , including seizure of the product. One notable case a few years ago involved an electrical device called the Relaxacisor, which had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life. Obviously, most of the devices on the market have never been the subject of court proceedings ,and new devices appear continually. Before buying, it is up to the consumer to judge the safety or effectiveness of such items. Question: It can be inferred that ads mentioned in the text are _ . Answer:

Read the following article and answer the question. Article: A new study says one part of the human brain may become smaller as the result of a condition known as jet lag. Jet lag results from flying long distances in an airplane. Jet lag interferes with a person's normal times for sleeping and waking. People with jet lag may feel extremely tired for several days. They also may have problems thinking clearly and remembering. Kwangwook Cho is a researcher at the University of Bristol in Britain. He reported the findings of his jet lag study in the publication Nature Neuroscience. The study involved twenty young women who worked for international airlines. The women had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights. The other half spent more than fourteen days in their home areas. Mister Cho took some fluid from the women's mouths to measure levels of a hormone that increases during stress. He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains using magnetic resonance imaging. This is a way to measure the size of the brain's temporal lobes. It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels of stress hormones. Mister Cho says he believes the brain needs at least ten days to recover after a long trip. He says airline workers told him their ability to remember got worse after working on planes for about four years. Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory. Scientists say more tests are needed to study the...
