Look at the pie charts and the graph and correct seven mistakes in the text.

The information shows the favourite hobbies of 12 to 16-year-olds in the 1980s and 2010s and the amount of exercise they have done over this period. The information shows that favourite hobbies have changed, and also that the amount of weekly exercise has decreased for some age groups.

In the 2010s, 12 to 14-year-olds prefer activities which involve exercise. We can see that in the 1980s just over two thirds of 12 to 14 year olds named playing sports as their favourite hobby, whereas in the 2010s this number was just under a third. In the 2010s, watching TV was the most popular hobby.

This change is also reflected in the amount of exercise done by this age group. Although the amount of exercise done by 14-year-olds remained about the same throughout this period, the amount of weekly exercise done by 13 and 14-year-olds rose. In 1980, 13-year-olds did 13 hours of exercise per week on average. This decreased to 8 hours per week in 2010. This drop was steeper in 14-year-olds, from 11 hours per week in 1980 to 3 hours per week in 2010.
