     Shopping for clothes is not the same    1   for a man as it is for a woman. A man goes shopping
because he needs something. His purpose is   2  and decided in __3__. He knows what he wants,
and his __4__ is to find it and buy it. All men simply walk into a shop and ask the assistant for what
they want. If the shop has it in stock, the  _5   can be and often is completed in less than five minutes,
with hardly any chat and to everyone's __6__. For a man, slight problems may begin when the shop
does not have what he wants. In that case the salesman tries to sell the customer something else-he offers
the nearest to the article  _7  . Good salesman brings out such a substitute with __8__: "I know this
jacket is not the __9   you want, sir, but would you like to try it for size. It happens to be the      10   
you mentioned." Few men have     11     with this treatment, and the  12  response is: "This is the right
color and may be the right size, but I should be wasting my time and yours by trying it on."
     For a woman, buying clothes is always done in the    13     way. Her shopping is not often     14    
on need. She has     15    fully decided what she wants, and she is only "having a look round". She is
always      16    to persuasion, willing to try on any number of things. Uppermost in her mind is the thought
of finding something that everyone thinks     17     her. Most women have an excellent sense of     18   
and are always on the look-out for the unexpected bargain. Faced with a roomful of dresses, a woman
may easily spend an hour going from one rail to another _ 19__ coming across the dresses she wants to
try on. It is a tiresome process, but obviously a(n)    20     one.
