Study the following graph and answer questions that follow. The x-axis denotes the years from 1983 to 1991
Going according to previous trends, one can say that the Fertilizer Production has shown an anomalous behavior in which year?
The fertilizer and food production has been inversely proportional over the years. ie when food production increased, fertilizer production fell and vice versa. But as we can see in 1988-89, when food production remained constant, the fertilizer production fell steeply and in 89-90 when food production increased steeply, the fertilizer production stayed constant. So, 1989 is the year of the anamoly.
