Solution

(i) By representing causes on x-axis and family fatality rate on y-axis and choosing an appropriate scale (1 unit = 5% for y axis), the graph of the information given above can be constructed as follows.

All the rectangle bars are of the same width and have equal spacing between them.

(ii) Reproductive health conditions are the major cause of women’s ill health and death worldwide, as 31.8% of women are affected by it.

(iii) The factors are as follows.
