He returned from his first visit to the place in late autumn, and could not get back until the snow melted in the following spring.Then he went to the pilot of a small plane, who earned his living by carrying hunters over parts of the country where there were no roads and no railways.He asked the pilot to take him back to the piece of forest.
The pilot did not know the place, so the hunter showed it to him on the map.“But there is nowhere to land there,” said the pilot.“I have flown over that we can’t land anywhere between this river and these mountains.”
“I thought you were a wonderful pilot,” said the hunter, “some of my friends said you could land a plane on a postage stamp.”
“That’s right,” answered the pilot.“I can land a plane where nobody else can.But I tell you there is nowhere to land in the place you are talking about.”
“And what if I tell you that another pilot did land me there last spring?” said the hunter.
“Is that true?” asked the pilot.
“Yes, it is.I swear it.”
Well, this pilot could not let himself beaten by another, so he agreed to take the hunter.
When they reached the place, the hunter pointed out a small spot without trees in the middle of the forest, with a steep rise(陡坡) at one end.The pilot thought there was not enough room to land there, but the hunter said that the other pilot had done so the year before, so down went the plane.When it came to the rise, it turned right over onto its back.As the hunter climbed out, he smiled happily and said, “Yes, that is exactly how the other pilot managed it last time.”.

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 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
