In this type of market, supply normally is very elastic--that is responsive to demand--in the short run. Stocks or inventories are held at some point in the chain of distribution; while stocks are running down or building up, there is time to change the level of production, and once a price has been set, it is rarely altered in response to moderate changes in demand. Even in a deep slump, defensive rings may be formed to prevent price cutting.
In the long run, as well as in the short, supply is responsive to demand in the market for manufactures. It is easier to change the composition of a firm's output than it is to change the production of a mine or a plantation. And when changes in demand are not too rapid, gross profits from one plant can be siphoned off and invested in something quite different. When business is good, moreover, there is continual new investment so that productive capacity is adapted to meeting changing requirements. Workers themselves may not even be aware of changes in the final commodities to which their work contributes, and the level of wages for any grade of factory labour is very little affected by the fortunes of a particular market.
The "imperfection" of the market for manufactured goods is reflected in all of the following aspects, except ______.
A．the distinctive style. of each company
B．the attempts of advertisement to attract buyers to particular brand names
C．tendency for the prices of the same goods to equalize quickly
D．the freedom of small businesses to decide the prices they will charge
Building a house costs quite a lot of money. Suppose you plan to build a house. Your first step will be to find a right piece of land. Your choice will depend on many different things. You will probably try to find a sunny place, with pleasant surroundings(环境)near shops and bus stops, not too far from your friends and the place where you work.
Next you will find a good builder, and together with the builder you will work out a plan. The builder will draw the plan. It will show the number of rooms, their position and size, and other parts, which must be noticed, such as windows, doors, and electric outlets.The builder will work out how much money is needed to build your house. He will work out the cost of the wood, bricks, the glass, and everything else that must be used in building the house. Later on, when he starts to build, this estimate(预算)must be corrected and revised(修订). His estimate is based on existing prices, but prices of such things may change, and many other things may happen between the time when he makes the estimate and the time when he builds the house.
When the builder gives his estimate, you may wish to change your plan. (You may also wish to change your builder, if his estimate is too high!) You may find that the house you wanted at first costs too much, or that you can spend a little more and add something to your plan. The builder's estimate depends on the plan, but the final plan depends on the builder's estimate.

As Gas Prices Increase, So Do Hardships
By Julie Livingston
Staff Reporter
With gas prices at more than $4 per gallon, many Upton citizens are being forced to break their regular routine and change their way of living.
In the past, high gas prices meant Uptonites would postpone their weekend trip or even summer vacation, but today, Uptonites are changing more than travel plans.
"I started riding my bike to run errands in town," said resident Dale Brown. "But I still have to commute into the city for work, and I'm paying nearly double in gas. I may have to look for a new job."
Not only are people riding bicycles more, buses have been fuller than usual, and the gas prices are forcing the city council to discuss increasing ticket prices by 20 cents.
Still many people are driving as usual, but filling their tanks only half way. "I get calls a few times per week that they've run out of gas, so I drive out to where they are and bring them gas," said Marty Watson, owner of Marty's Gas Station. "It's a shame that [the gas] is not as affordable, so people fill up less and get stuck."
What problem is being discussed？
A．Lower wages
B．Higher fuel prices
C．Rising unemployment
D．Higher healthcare costs
