IELTS Task 1-1 Given are three bar charts comparing the average years of school, number of scientists and technicians and research &development expenditure among developing and industrialized countries in 1980 and 1990. In term of the number of average years of schooling received, in 1980, people in industrialized area gained approximately 8 years education in average while people in developing area merely received 2 years education in average. After 10 years, the gap had widened slightly with 11 years in industrialized countries and 3 years in developing countries. As for the number of scientists and technicians, there are similar trend as first graph has been seen. For industrialized countries, the number was around 42 scientists and technicians per 1,000 people in 1980, and then had increased to 70 people in 1990. However, developing area merely saw slight progress from 10 people per 1,000 people in 1980 to 18 people in 1990. Finally, regard with R&D investment, affluent countries, around 150 billion dollars in 1980 and 350 billion dollars in 1990 were been invested. Conversely, in less affluent countries, only 50 billion dollars in 1980 was spent and its investment even decreased half amount after 10 years. Overall we can see that industrialized countries implicated longer education period, fostered more scientists and technicians and invested more capital on R&D compared with developing countries.
