The line graph compares the cost of four distinct 800-gram breads in one European country between 2001 and 2005.
Overall, the prices of all types of bread were the same except for wholegrain in the initial year. While all figures exhibited an upward trend in general throughout the period, the price of wholegrain experienced a surge at first before falling back to the previous place.
Focusing first on the cost of brown and white bread, which underwent a wilder increase, commencing at 0.6 in 2001, the price rose abruptly to 1.5 and 1 in 2002, respectively. In the following year, the price of brown bread went up slightly by 0.1 prior to dropping to 1.4 in 2004 and eventually reaching 1.6, becoming dominant among others, whereas the price of white bread grew continually to around 1.3 by the end of the year.
Turning to the cost of wholegrain and rye, unlike others, starting at 0.8 and 0.6, the former witnessed a swift rise, peaking at 1.8 and the latter observed a slight decrease to about 0.5 in 2002. The cost of rye increased slowly to approximately 0.7 by 2005, which made it the lowest figure in the graph. By contrast, that of wholegrain fell dramatically to 0.7 in 2005 before recovering to 0.8 in 2005.
