Grain Harvests of Countries M and Z

　　According to the chart showing the grain harvests of Countries Z and M from 1977 to 1979, 1977 was the best year because the outputs of both countries were the highest. The total yield of Country Z reached 450 millions of bushels while the record of Country M was 400 millions of bushels. Whatever happened to the two countries in the following year is unknown, but obviously both countries, especially Country Z suffered a severe setback in production in 1978: The annual output of Country Z, sank to 270 millions of bushels, forming only three fifths of the 1977 record. Country M was no better, too. Its total harvests in the year were 80 millions of bushels less than the previous year. Fortunately, the year 1979 witnessed a significant revival in agriculture for both Countries Z and M, whose grain harvests rose to 400 and 380 millions of bushels respecitively. Either the total harvests increased or decreased, the production of different crops in the two countries remained consistent throughout the three years. Wheat and corn were the two major crops in both countries, but Country Z seemed to rely more on wheat whereas Country M on corn.
