Question

which increases in boys more than girls in middle childhood?
a mental activity
b internal attributions
c mastery orientation
d physical activity

Explanation:

In middle childhood, physical activity levels tend to increase more in boys than in girls. This is often due to social and biological factors. Socially, boys may be encouraged more to engage in rough - and - tumble play and sports. Biologically, differences in hormones and physical development can also play a role. Mental activity, internal attributions, and mastery orientation do not show such a clear - cut gender difference in terms of a greater increase in boys during middle childhood.

Answer:

D. Physical activity
