We may think of the American economy, as consisting of two completely different sectors.The world of the giant corporations, which can be called the "industrial system", consists of 500 or 600 firms that provide "nearly all communications, nearly all production and distribution of electric power, much transportation, most manufacturing and mining, a substantial share of retail trade, and a considerable amount of entertainment." Outside of this industrial system fall most agricultural enterprises, some mining and trucking, professional and artistic pursuits, some retail trade, and most personal and domestic services.
The classical economic laws of supply and demand still apply to some degree.But today the industrial sector is characterized far more by planning and certainty than by the free play of market forces.It appears that it could scarcely be otherwise.In large corporations with advanced technological systems and complex organizations of highly trained specialists, plans for producing any one item are made well in advance.Such plans, once made, are hard to change.Because long-term planning demands certainty, market forces are avoided by various means.For example, the corporation may achieve "vertical integration" by buying companies that supply raw materials at one end of the process and distribution outlets at the other.Corporations may agree on "just prices" for things they buy and sell.They may enter mutually advantageous long-term contracts with suppliers and customers.Moreover, in their quest for certainty they generally have the support of the state.

A) highly educated managers are important for the corporations
B giant corporations become decentralized

A retail trade accounts for a big part in non-industrial system
B there are more giant corporations than agricultural enterprises

28.From the whole passage, we can infer that American economy .
A is experiencing the rise of giant corporations
B is determined by hundreds of giant corporations
C has failed to balance supply and demand
D becomes highly-planned one
29.In the third sentence of last paragraph, the second "it" may refer to.
A classic economic law of supply and demand
B industrial sector
C American economy
D market force
30.Which of the following is not mentioned in the passage?
A American economy is characterized by high technology and giant corporations.
B American economy consists of industrial systems and agricultural enterprises.
C.Market economy is gradually replaced by planned economy.
D Highly trained specialists are needed.

An important factor in a market-oriented economy is the mechanism by which consumer demands can be expressed and responded to by producers. In the American economy, this mechanism is provided by a price system, a process in which prices rise and fall in response to relative demands of consumers and supplies offered by seller-producers. If the product is in short supply relative to the demand, the price will be a bit up and some consumers will be eliminated from the market. If, on the other hand, producing more of a commodity results in reducing its cost, this will tend to increase the supply offered by seller-producers, which in turn will lower the price and permit more consumers to buy the product. Thus, price is the regulating mechanism in the American economic system.
The important factor in a private-oriented economy is that individuals are allowed to own productive resources (private property), and they are permitted to hire labor, gain control over natural resources, and produce goods and services for sale at a profit. In the American economy, the concept of private property embraces not only the ownership of productive resources but also certain rights, including the right to determine the price of a product or to make a free contract with another private individual.
