 Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions.
Psychologists have debated a long time about whether a child’s upbringing can give it the ability to do outstandingly well. Some think that it is impossible to develop genius and say that it is simply something a person is born with. Others, however, argue that the potential for great achievement can be developed. The truth lies somewhere between these two extremes. It seems very obvious that being born with the right qualities from gifted parents will increase a child's ability to do well. However, this ability will be fully realized only with the right upbringing and opportunities. As one psychologist says, “To have a fast car, you need both a good engine and fuel.” Scientists have recently assessed intelligence, achievement, and ability in 50 sets of identical
twins that were separated shortly after birth and brought up by different parents. They found that achievement was based on intelligence, and later influenced by the child's environment. One case involving very intelligent twins was quoted. One of the twins received a normal upbringing, and performed well. The other twin, however, was brought up by extremely supportive parents and given every possible opportunity to develop its abilities. That twin, though starting out with the same degree of intelligence as the other, performed even better. This case reflects the general principle of intelligence and ability. The more favorable the environment, the more a child's intelligence and ability are developed. However, there is no link between intelligence and the socioeconomic level of a child's family. In other words, it does not matter how poor or how rich a family is, as this does not affect intelligence. Gifted people cannot be created by supportive parents, but they can be developed by them. One professor of music said that outstanding musicians usually started two or three years earlier than
ordinary performers, often because their parents had recognized their ability. These musicians then needed at least ten years' hard work and training in order to reach the level they were capable of attaining.
People who want to have very gifted children are given the following advice.
• Marry an intelligent person.
• Allow children to follow their own interests rather than the interests of the parents.
• Start a child's education early but avoid pushing the child too hard.
• Encourage children to play; for example, playing with musical instruments is essential for a child who wants to become an outstanding musician.

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions.

In the world today, particularly in the two most industrialized areas, North America and Europe recycling is big news. People are talking about it, practicing it, and discovering new ways to be sensitive to the environment. Recycling means finding ways to use products a second time. The motto of the recycling movement is “Reduce, Reuse, Recycle”. The first step is to reduce garbage. In stores, a shopper has to buy products in blister packs boxes and expensive plastic wrappings. A hamburger from a fast food restaurant comes in lots of packaging: usually paper, a box, and a bag. All that packaging is wasted resources. People should try to buy things that are wrapped simply, and to reuse cups and utensils. Another way to reduce waste is to buy high-quality products. When low quality appliances break, many customers throw them away and buy new ones - a loss of more resources and more energy. For example, if a customer buys a high-quality appliance that can be easily repaired, the manufacturer receives an
important message. In the same way, if a customer chooses a product with less packaging, that customer sends an important message to the manufacturers. To reduce garbage, the throwaway must stop.
The second step is to reuse. It is better to buy juices and soft drinks in returnable bottles. After customers empty the bottles, they return them to the store. The manufacturers of the drinks collect the bottles, wash them and then fill them again. The energy that is necessary to make new bottles is saved. In some parts of the world returning bottles for money is a common practice. In those places, the garbage dumps have relatively little glass and plastic from throwaway bottles.
The third step is being environmentally sensitive is to recycle. Spent motor oil can be cleaned and used again. Aluminum cans are expensive to make. It takes the same amount of energy to make one aluminum can as it does to run a color TV set for three hours. When people collect and recycle aluminum (for new cans), they help save one of the world’s precious resources.
