Answer with explanation:
Part A
The given graph is a line graph, represents increasing and decreasing rainfall in six different years.
The given graph misleads ,in terms of length, when amount of rainfall(4.6-3.9) is plotted with six different years(2006-2011).
→→When rainfall decreases from 4.5 to 4.4, the decrease , in length of rectangle is less,should be equal, in comparison to when year increases from 2006 to 2007. It must be in the shape of Square.
Part B
If instead of line graph, we will draw bar graph ,representing Amount of rainfall(4.5-3.0) on y axis in the month of July, to 6 different years from (2006-2011) on x axis,i think it will be least misleading.
