【正确答案】This is a bar chart illustrating the changes of reasons for study in different age groups. As is shown, there is a gradual decrease of career reasons for study with age growing. Nearly 80% of people under 26 study for their career. This percentage gradually declines by 10-20% every decade. Only 40% of the 40-49 years old and 10% of over 49 years old are studying for career reasons in late adulthood. Conversely, study stemming from interest increases with age rising. There are only 10% of people under 26 studying out of interests. The percentage increases slowly till the beginning of the fourth decade, and goes up dramatically in late adulthood. Nearly the same number of the 40-49 years old study for career and interest. However, 70% of over 49 years old study for interest in comparison to less than 20% studying for career in that age group.
