The two bar charts illustrate the changes in the wheat production and the average prices between 1990 and 2000 in a European country.

　　The first chart reveals that the decade saw a sharp increase in the production. In 1990 the European country output approximately 0.8 millions of tonnes. Till 2000 the figure peaked at about 2.4 million, a three time jump.

　　According to the second chart, the wheat prices dramatically surged from less than 1500 Pound Sterling per tonne in 1990 to almost 3000 in 1995. Nevertheless, in the following five years, the changes in prices were featured by decrease. By 2000, the prices had dropped to 2,200 pound sterling.

　　Obviously, the changes in the production were not the same as those in the prices during the ten years.

　　Bristol factories, with 600 employees in 2003, generated the largest profits in each quarter during 2003. But the profits reduced from ￡12 million in the first quarter to about ￡8.2 million in the fourth.

　　London factories, by contrast, contributed the least in the whole year. Although the profits slightly climbed in the second quarter, they declined in the following periods. The highest profits in the second quarter reached ￡4.1 million.

　　The profits produced by the Leeds factories were relatively stable in that only in the third quarter did the profits dropped by one million pound sterling to the bottom of ￡7million . The other three quarters saw the same profits.

　　Noticeably, the number of employees in Leeds was 350, compared with 150 in London.
