The given bar charts compares the educational involvements of students in terms of total years of education and their participation in science related subjects and study in developing and industrialised countries from 1980 to 1990.

According to the first bar graph, the average years of schooling in developing counties was only about 2 while this was over 8 years in industrialised countries in 1980. After ten year, the number of year in school in an average increased both in the developing and industrialised countries reaching just over 3 years in developing countries while over 10 years in developed countries.

According to the second graph, the number of Scientist and Technician was much higher in developed countries than the developing countries. The percentage of Scientist and Technician in developing countries both in 1980 and 1990 was below 20 while this was around 50 on an average in developed countries.

Finally, the third graph represents that the amount spent on Research and Development in industrially developed countries was much higher than the spending in developing countries. In 1980 the spending was around 50 billion US dollar in developing countries while this amount was more than 150 billion US dollar in developed countries. Interestingly, after 10 years the spending in Research & Development in developed countries was doubled while that amount decreased almost by 50% in developing countries.

Sample Answer 2:
The given bar graphs compare the educational involvements of students in term of total years of education and their participation in science related subjects in developing and industrial countries from year 1980 to 1990.

As is presented in first bar graph, average years of schooling in developing countries were approximately 2 years while in industrial countries schooling years were over 8 years in 1980. Interestingly after one decade schooling years in developing countries magnified to over 3 years while it surged to over 10 years in industrial countries.

As is observed from second bar graph, number of scientists and technicians were much higher in industrial countries than in developing countries. Percentage of scientists and technicians were less than 20 percent in developing countries from 1980 to 1990 while it was just over 40 percent in 1980 which soared to approximately 70 percent in 1990.

According to third bar graph, it can be seen clearly, spending on research and development in industrial countries was much more higher than developing countries. The spending in 1980 in developing countries was around 50 billion US dollars while it was 150 billion dollars in industrial countries. Ultimately, after a decade spending on research and development slumped significantly almost 50 percent while spending in industrial countries peaked to approximately 350 billion US dollars respectively.
