Question: Read the article and select the best answer. Article: A new Australian research indicates that children with a stutter do not suffer disadvantages at school, More than ten percent of children have a stutter by the age of four but they score just as high as other children on tests designed to judge their language, thinking skills and character. Professor Reilly's team studied over 1600 children from Melbourne, Australia. Their mothers had been filling out regular questionnaires since their babies were eight months old and the children were judged by a range of language and behaviour tests when they reached the age of four. Reilly and her colleagues asked the parents to call the study group if their children started showing signs of stuttering. Diagnoses were confirmed by a researcher, who then visited the homes of children with a stutter every month to check on their progress. By the age of four, 181 of the children studied had been diagnosed with a stutter. Follow-up visits to the 181 children who were judged after diagnoses showed just nine no longer had a stutter one year later. Stuttering children scored 5. 5 points higher than that of their non-stuttering children on language tests and 2. 6 points higher on the test of non-verbal intelligence. The researchers said it was possible that stuttering could improve language skills, or that stuttering could result from very fast language development among some children. The research suggests parents of children who stutter are usually advised to wait a year before looking for treatment --which can be expensive -- to see if the stutter goes away by itself, unless the children become very unhappy or stop talking.

Question: Read the article and select the best answer. Article: Supply and demand is perhaps one of the most basic concepts of economics and it is the backbone of a market economy. Demand refers to how much of a product or service is desired by buyers. The quantity demanded is the amount of a product people are willing to buy at a certain price; the relationship between price and quantity demanded is known as the demand relationship. Supply represents how much the market can offer. The quantity supplied refers to the amount of a certain goods producers are willing to supply when receiving a certain price. The relationship between price and how much of a goods or service is supplied to the market is known as the supply relationship. Price, therefore, is a reflection of supply and demand. The law of demand states that, if all other factors remain equal, the higher the price of a product, the fewer people will demand that product. The amount of goods that buyers purchase at a higher price is less as the price of a product goes up, so does the opportunity cost of buying that product. Like the law of demand, the law of supply shows the quantities that will be sold at a certain price. But unlike the law of demand, the supply relationship shows an upward slope. This means that the higher the price, the higher the quantity supplied. Producers supply more at a higher price because selling a higher quantity at a higher price increases the whole income. Now that we know the laws of supply and demand, let's turn to an example to show how supply and demand affect price. Imagine that a CD of your favorite band is sold for $20. Because the record company's previous analysis showed that consumers will not demand CDs at a price higher than $20, only ten CDs were sold because the opportunity cost is too high for suppliers to produce more. If, however, the ten CDs are demanded by 20 people, the price will then rise. As a result, the rise in price should cause more CDs to be supplied as the supply relationship shows that the higher the price, the higher the quantity supplied. If,...

Options: A: to persuade people to buy more products B: to let people know more about a CD C: to explain the relationships between demand, supply and price D: to tell people how to buy things reasonably
