潜育期（incubation period）

Shopping for clothes is not the same experience for a man as it is for a woman. A man goes shopping because he needs something. He knows what he wants, and his purpose is to find it and buy it, the price is a less important consideration. All men simply walk into a shop and ask the assistant for what they want. If the shop has it, the salesman immediately produces it, and the business of trying it on is done at once. All being well, the bargain (交易) can be and often is completed in less than five minutes, with hardly any chat and to everyone’s satisfaction.
For a man, slight problems may begin when the shop does not have what he wants. Then the salesman tries to sell the customer (顾客) something else he offers the nearest he can to the thing required. He usually says, "I know this jacket is not the style (式样) you want, sir, but would you like to try it on for size It happens to be the color you wanted." Few men have patience with this treatment, and the usual reply is: "This is the right colour and may be the right size, but I should be wasting my time and yours by trying it on."
Now how does a woman go about buying clothes She does so in the opposite way. She has never fully made up her mind what she wants, and she is only "having a look round". She is always open to persuasion, indeed she considers of great importance what the saleswoman tells her, even what her friends tell her. She will try on any number of things. Highest in her mind is the thought of finding something that everyone thinks suits her. Most women have an excellent sense (判断力) of value when they buy clothes. They are always trying to find an unexpected bargain. Faced with a roomful of dresses, a woman may easily spend an hour going from one counter (柜台) to another before selecting the dresses she wants to try on. It takes a great deal of time but gives great joy. Most dress shops supply chairs for the waiting husbands.

The most obvious difference between men and women shoppers is ______.

A. that men do not try clothes on in a shop while women do
B. that women bargain for their clothes and men don’t
C. that women do their shopping standing up but men do theirs sitting down
D. the time they take over buying clothes
