input: OPTIONS:
- The more goods the better.
- The more mental satisfaction the better.
- The more "luxury" items the better.
- The more earnings the better. Now, answer this question: Read the following article and answer the question. Article: Human needs seem endless. When a hungry man gets a meal, he begins to think about an overcoat, when a manager gets a new sports car, a big house and pleasure boats dance into view. The many needs of mankind might be regarded as making up several levels. When there is money enough to satisfy one level of needs, another level appears. The first and most basic level of needs involves food. Once this level is satisfied, the second level of needs, clothing and some sort of shelter, appears. By the end of World War II, these needs were satisfied for a great majority of Americans. Then a third level appeared. It included such items as automobiles and new houses. By 1957 or 1958 this third level of needs was fairly well satisfied. Then, in the late 1950s, a fourth level of needs appeared; the "life-enriching" level. While the other levels involve physical satisfaction, that is, the need in comfort, safety, and transportation, this level stresses mental needs for recognition, achievement, and happiness. It includes a variety of goods and services, many of which could be called "luxury" items. Among them are vacation trips, the best medical and dental care, and recreation. Also included here are fancy goods and the latest styles in clothing. On the fourth level, a lot of money is spent on services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of needs as their income increases, or will they continue to demand luxuries and personal services on the fourth level? A fifth level would probably involve needs that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime, and prejudice. After filling our stomachs, our clothes closets, our garages, our teeth, and our minds, we now may seek to ensure the health, safety, and leisure to enjoy more fully the good things on the first four levels. Question: What is the main concern of man on the fourth level? Answer:
A:
output: The more mental satisfaction the better.

input: OPTIONS:
- a new substance
- nothing new
- a piece of paper
- a piece of iron Now, answer this question: Read the following article and answer the question. Article: There are two kinds of changeschemical change and physical change. In a chemical change, there is always a new substance formed. Breaking up water into hydrogen and oxygen is a chemical change. In each of the chemical change at least one new substance is formed. A change is not a chemical change if it doesn't form a new substance. Physical changes are very common, too. There are many examples. You can make a physical change by tearing a piece of paper into two, or by cutting a piece of iron with lathe . Here paper is still paper, and the iron is still iron. Another way of making physical change is dissolving something in water. When you dissolve salt in water, the salt disappears. You may think that a new substance has been formed. But really there is no new substance. The salt is still salt. You can still taste it. So the dissolving of anything is a physical change. When water freezes, the change is also a physical one. The water changes from liquid to solid, but it is still the same substance. That is why the freezing of anything is a physical change. Question: In a physical change _ .is formed. Answer:

Once his hearing memory has been greatly improved, he'll be able to use and remember what he listens to in class. The success of these suggestions depends upon your ability to use your child's natural desire to get involved in games he finds simple and fun. A good way to begin is to read aloud a sentence from a book suitable for your child's reading age. Then ask your youngster to repeat the sentence back to you correctly. Next, reread the sentence, leaving out a particular word. See if your child can identify the word you left out. At the beginning use only simple sentences. Gradually, increase the length of the sentences. Make sure you don't rush things along too quickly, or your child may become discouraged and tired of the game. Take your child shopping with you often. He's to remember a list of items you want to buy in the supermarket. First , ask him to remember only a few things. Then, as he shows increased ability to remember, make the list longer and longer. Praise him often and warmly when he shows increased ability to remember things. He'll become proud of his 'good' memory and will happily play the game. Encourage your child to learn easy and short poems. As his ability to do this becomes stronger, encourage him to remember longer poems. Do the same with songs. Question: Who are the supposed readers of this passage? Answer:
