on a smaller scale, faces practically every company trying to develop new products and create new jobs. They can be little prospect of raising the sort of sums needed from friends and people we know, and while banks may agree to provide short-term finance, they are generally unwilling to provide money on permanent basis for long-term project. So companies mm to the public, inviting people to lend them money, or take a share in the business through the Stock Exchange. By doing so they can put into circulation the saving of individuals and institutions, both at home and overseas.

When the saver needs his money back, he dose not have to go to the company with whom he originally placed it. Instead, he sells his shares through a stockbroker to some other saver who is seeking to invest his money.

Many of the services needed both by industry and by each of us are provided by the Government or by local authorities. Without hospitals, roads, electricity, telephones, railways, this country could not function. All these require continuous spending on new equipment and new development if they are to serve us properly, requiring more money than is raised through taxes alone. The Government, local authorities, and nationalized industries therefore frequently need to borrow money to finance major capital spending, and they, too, come to the Stock Exchange.

There is hardly a man or woman in this country whose standard of living dose not depend on the ability of his or her employers to raise money to finance new development. In one way or another this new money must come from the savings of the country. The Stock Exchange exists to provide a channel through which these savings can reach those who need finance.

Almost ail companies involved in new production and development must ______.

A．rely on their own financial resources

B．persuade the banks to provide long-term fin0ance

C．borrow large sums of money from friends and people they know

D．depend on the population as a whole for finance

ss and which determines in some ways the extent of our achievements. Since the Intelligence Quotient was relatively unaffected by bad teaching or a dull home environment, it remained constant. Its value, therefore, was a predictor of children's future learning. If they differed markedly in their ability to learn complex tasks, then it was clearly necessary to educate them differently—and the need for different types of school and even different ability groups within schools was obvious.

Today, we are beginning to think differently. In the last few years, re search has thrown doubt on the view that innate intelligence can ever be measured and on the very nature of intelligence itself. Perhaps most important, there is considerable evidence now which shows the great influence of the environment both on achievement and intelligence. Children with poor home backgrounds not only do less well in their school work and in intelligence tests—a fact which could be explained on genetic grounds—but their performance tends to deteriorate gradually compared with that of their more fortunate classmates. Evidence like this lends support to the view that we have to distinguish between genetic intelligence and observed intelligence. Any deficiency in the appropriate genes will obviously restrict development, no matter how stimulating the environment. But we cannot observe or measure innate intelligence; whereas we can observe and measure the effects of the interaction of whatever is inherited with whatever stimulation has been received from the environment. Changes may occur in our observations or measurements, if the environment is changed. In other words, the Intelligence Quotient is not constant.

Researches over the past decade have been investigating what happens in this interaction. Work in this country has shown that parental interest and encouragement are more important than the material circumstances of the home.

Two major findings have emerged from these studies. Firstly, that the greater part of the development of observed intelligence occurs in the earliest years of life. 50 percent of measurable intelligence at age 17 is already predictable by the age of four. In other words, deprivation in the first four or five years of life can have greater consequences than any of the following twelve or so years.

Secondly, the most important factors in the environment are language and psychological aspects of the parent-child relationship. Much of the difference in measured intelligence between "privileged" and "disadvantaged" children may be due to the latter's lack of appropriate verbal stimulation and the poverty of their perceptional experiences.

These research findings have led to a revision in our understanding of the nature of intelligence. Instead of it being some largely inherited fixed power of the mind, we now sec it as a set of developed skills with which a person copes with any environment. These skills have to be learned and, indeed, the fundamental one is learning how to learn.

Which of the following might serve as a suitable title for the passage？

A．Intelligence: A Changed View

B．Intelligence and Intelligence Quotient

C．Genetic Intelligence vs Observed Intelligence

D．Innate Intelligence and Developed Skills
