We must therefore define a market 【32】______ any area over which buyers and sellers are 【33】______ such close touch with one another, either directly or 【34】______ dealers, that the prices 【35】______ in one part of the market affect the prices paid in other parts. Modem means of communication are so rapid that a buyer can discover 【36】______ asking, and can accept it if he wishes, 【37】______ he may be thousands of miles away. Thus the market for anything is 【38】______ . the whole world. But in fact things have, normally, only a local or national market. This may be because nearly the whole demand is concentrated 【39】______ one locality. These special local demands, 【40】______ , are of quite minor importance. The main reason why many things do not have a world market is that they are costly or difficult to transport. 【21】
