根据下面内容，回答176-180题The traditional distinction between products that satisfy needs and those that satisfy wants isno longer adequate to describe classes of products．In today's prosperous societies the distinctionhas become blurred because so many wants have been turned into needs．A writer, for instance,can work with paper and pencils．These are legitimate needs for the task．But the work can be donemore quickly and efficiently with a word processor．Thus a computer is soon viewed as a needrather than a want.In the field of marketing, consumer goods are classed according to the way in which they arepurchased．The two main categories are convenience goods and shopping goods．Two lesser typesare specialty goods and unsought goods．It must be emphasized that all of these types are based onthe way shoppers think about products, not on the nature of the products themselves．What is re-garded as a convenience item in France (wine, for example) may be a specialty good in the UnitedStates.People do not spend a great deal of time shopping for such convenience items as groceries,newspapers, toothpaste, razor blades, aspirin, and candy．The buying of convenience goods maybe done routinely, as some families buy groceries once a week．Such regularly purchased items arecalled staples．Sometimes convenience products are bought on impulse: someone has a sudden de-sire for an ice cream sundae on a hot day．Or they may be purchased as emergency items.Shopping goods are items for which customers search．They compare prices, quality, andstyles, and may visit a number of stores before making a decision．Buying an automobile is oftendone this way．Shopping goods fall into two classes: those that are perceived as basically the sameand those that are regarded as different．Items that are looked upon as basically the same includesuch things as home appliances, television sets, and automobiles．Having decided on the modeldesired, the customer is primarily interested in getting the item at the most favorable price．Itemsregarded as inherently different include clothing, furniture, and dishes．Quality, style, and fashionwill either take precedence over price, or they will not matter at all.Specialty goods have characteristics that impel customers to make special efforts to find them.Price may be no consideration at all．Specialty goods can include almost any kind of product．Nor-mally, specialty goods have a brand name or other distinguishing characteristics.Unsought goods are items a consumer does not necessarily want or need or may not even knowabout．Promotion or advertising brings such goods to the consumer's attention．The product couldbe something new on the market as the Sony Walkman once was or it may be a fairly standard ser-vice, such as life insurance, for which most people will usually not bother shopping. A word processor can be looked on as satisfying（）rather than if it be-comes the only means to an end.
