The cause of tooth decay is acid, which is produced by bacteria in the mouth. The acid removes minerals from tooth enamel, allowing tooth decay to begin; the saliva in your mouth encourages remineralization and neutralizes the acid. The rate at which bacteria in the mouth produce acid depends on the amount of plaque on the teeth, the composition of the microbial flora, and whether the bacteria of the plaque have been "primed" by frequent exposure to sugar. To keep your teeth healthy, a regular dental hygiene program should be followed.
Removing plaque with a toothbrush and dental floss temporarily reduces the numbers of bacteria in the mouth and thus reduces tooth decay. It also makes the surfaces of the teeth more accessible, enabling saliva to neutralize acid and remineralize lesions. If fluoride is present in drinking water when teeth are forming, some fluoride is incorporated into the enamel of the teeth, making them more resistant to attack by acid. Fluoride toothpaste seems to act in another way, by promoting the remineralization of early carious lesions.
In addition to a regular dental hygiene program, a good way to keep your teeth healthy is to reduce your intake of sweet food. The least cavity-causing way to eat sweets is to have them with meals and not between. The number of times you eat sweets rather than the total amount determines how much harmful acid the bacteria in your saliva produce. But the amount of sweets influences the quality of your saliva. Avoid, if you can, sticky sweets that stay in your mouth a long time. Also try to brush and floss your teeth after eating sugary foods. Even rinsing your mouth with water is effective. Whenever possible, eat foods with fiber, such as raw carrot sticks, apples, celery sticks, etc., that scrape off plaque, acting as a toothbrush. Cavities can be greatly reduced if these rules are followed when eating sweets.

We can infer from the passage that one benefit of fluoride to healthy teet

Read the following passage and choose the best answer (A, B, C, D):
The custom of paying a bride price before marriage is still a well-established part of many African cultures. In paying a bride price, the family of the groom must provide payment to the family of the bride before the marriage is allowed. The bride price can vary greatly from culture to culture in Africa. In the Zulu and Swazi tribes of southern Africa, the bride price often takes the form of cattle. In Western African, kola nuts, shells, and other goods are often used for the payment of the bride price. The actual payment of money sometimes takes place, but the payment of goods is more frequent. The amount of paid in a bride price can also vary. In modern times, the bride price is occasionally quite small and its value is mainly symbolic. However, the bride price can still be quite high, especially among prominent or highly traditional families.There are a number of justifications used to explain the payment of bride price. The first is that the bride price represents an acknowledgement of the expense the bride's family has gone in order to raise her and bring her up as a suitable bride for the groom. It also represents payment for the loss of a family member, since the bride will officially become a member of her husband's family and will leave her own. On a deeper level the bride price represents payment for the fact that the bride will bring children into the family of the groom, thereby increasing the wealth of the family. This concept is reinforced by the fact that the bride price must often be returned if the bride fails to bear children.The payment of the bride price has quite a number of effects on African society. First, the payment of bride price acts to increase the stability of African family structures. Sons are dependent on their fathers and older relatives to help them pay the bride price of their wives, and this generally leads to greater levels of obedience and respect. The negotiations between the two families concerning the bride price allow the parents and other family members to meet and get to know one another before the marriage. Finally, since the bride price must often be repaid in case of divorce, the bride's family often works to make sure that any marital problems are solved quickly. Bride prices also work as a system of wealth distribution in African cultures. Wealthier families can afford to support the marriage of their son, and thus their wealth is transferred to other families.Not all of the effects of bride price are so positive, however. One major disadvantage to the system of bride price is that women are often married to men much older than themselves. In many African cultures, the typical age for marriage amongst women is still quite young, lower than in many cases. Yet few men at this age would have the ability to raise the bride price to marry. Thus there is sometimes a significant age gap between husbands and wives. This cuts short the education of many young women. In addition, the husband, being far older, may die whilst the wife is still relatively young, leaving her with the burden of raising the children alone.
1. According to paragraph 1, all of the following are true of the bride price EXCEPT ______

The Brain: Myths and Facts
There are a lot of myths about the human brain. We are going to tell you a little about these myths, and we are also going to give you the truth. One of the biggest myth is that we only use 10 percent of our brains. The next part of that myth is that if we can learn to use the rest of our brains, then we will be much smarter. People say this all the time, but it is absolutely not true. The truth is that although we don’t know everything about the human brain, we know that each part of it has an important function. Modern scientists call the “10 percent myth” ridiculous. The other most popular myth is about being “right brained” or “left brained”. According to this myth, people who use the right side of their brains tend to be more artistic and creative. People who use the left side of their brains tend to be better at maths and science. This myth is as popular as the 10 percent myth, and it is also wrong. In 2013, a study at an American university examined the right brain and left brain myth. According to the study, we use both sides of our brains equally. It is true that we use different parts of our brains for different things: We use our left side for language more, and our right side when we need to pay attention. But there is no evidence that creative people use the right side more, or that scientific people use the left side more. We have talked about myths, so let’s look at a few interesting facts about the brain. First of all, the brain feels no pain. Second, about 75 percent of the brain is made of water. It is also the fattest organ in your body. Another interesting fact about the brain is that around the time you turn 18 years old, it stops growing.

Say Sayonara to Sushi?
There are few meals as nutritious as a plate of fresh fish. Whether eaten steamed or raw, fish provides our bodies with healthy fats and it tastes great, too. Yet for years, the fishing industry has practised overfishing, depleting the world’s oceans. It has been estimated that 85 percent of stocks worldwide have been diminished to a dangerous level. Statistics show that the average person consumes more than four times as much fish as someone from the 1950s. As the world’s population grows and more people are able to afford pricier foods, the problem will likely get worse. In truth, knowledge of the shortage of fish is not something new. Since the late 1980s, despite increased technology and a greater demand for fish, the total global catch has not increased. Eager to make a buck, some fishermen have resorted to illegal tactics to catch more fish and increase their income. They will violate regulations by fishing in waters that are supposed to be off-limits. To make matters worse, they often use mile-long drift nets which trap and kill large numbers of unwanted marine life for no reason at all. These practices only serve to destroy fishes’ habitats and speed up the rate of population decline. As a result of dwindling fish supplies, many nations are turning to farmed fish. About half of the fish sold today is derived from this practice. Supporters point out its efficiency and that it is more feasible to support populations in this manner than with land animals. However, there are still many hurdles to overcome. Many of the current farm fisheries are poorly run by their owners. Poor practices can lead to marine pollution, as waters can be filled with fish manure and extra feed that is not consumed. Some farmed fish have limited space, which causes disease. This in turn can lead to health issues for the people who consume the fish. Still, some regard fish farming as the way of the future. They suggest that with a few modifications, it would be possible to meet the growing demand for fish. Others have suggested more drastic measures, such as placing a ten-year ban on capturing some species, to deal with the shortage. These people argue that a decade would provide sufficient time for the fish population to replenish itself hack to healthy levels. Hopefully, nations can come together and agree upon an effective course of action before it is too late.

Some technological developments are the results of years of diligent work. Others are stumbled upon by accident. The discovery of X-rays is in the second category. In 1895, X-ray radiation was accidentally discovered by a physicist named Wilhelm Rontgen, while he was working in his lab. Rontgen discovery greatly advanced medical science. One night in 1895, Wilhelm Rontgen was working with an electric device called a Crookes tube. A Crookes tube is a glass tube with metal components inside it. When turned on, the tube produces a stream of electrons. Rontgen and other scientists observed a new form of energy escaping from the front end of the Crookes tube. Rontgen wanted to be the first to discover this new mysterious energy. To do this, he needed to make sure the tube was covered with black cardboard. This would make the room completely dark and allow him to better see this new form of energy. Rontgen was hoping to observe this new energy on a special screen that would be placed right in front of the Crookes tube. Amazingly, before the screen was placed near the Crookes tube, Rontgen already noticed the screen was glowing. He bought the screen closer, and the glow became brighter. (1) He then placed a book between the end of the tube and the screen-the glow was still there. (2) Rontgen realized that a new and different form of radiation must be causing the screen to glow. (3) As he didn't know what kind of radiation it was, he named it "X". (4) Rontgen soon started studying the new type of radiation. He designed experiments which allowed him to test how far X- rays could penetrate. He also had the bright idea of trying to take photographs with X-rays. One day, he tested his theories by asking his wife to put her hand between a photographic plate and a Crookes Tube. Sure enough, the resulting image of the bones in his wife's hand was the first ever X-ray photograph of the human body. After taking that first photograph, Rontgen understood how X-rays could benefit doctors and patients. He shared his discovery, and soon X-ray machines were appearing in hospitals. X-rays were very useful for medicine because they let doctors see a patient's bones. If a patient had a broken bone, it was made visible by the X-ray image. This let doctors know the right way to repair the fracture. Wilhelm Rontgen's accidental discovery has now been helping people for over one hundred years. Thanks to X-rays, broken bones can be repaired reliably and effectively. We should be grateful to Wilhelm Rontgen for making his discovery freely available and greatly advancing medical science. Because of this, we humans are able to live longer, healthier lives.
