Explanation:

Here Environment Sociocultural constraints are responsible for not galloping while under assessment.  

There are two types of environmental constraints which are

In Physical Environmental constraints we refer to gravity, surface, temperature, and weather. In this case, all these factors are the same as we are accessing a group of 3 to 5-year-old groups.

While in Sociocultural Environmental constraints there may be variations in terms of gender roles, cultural norms, expectations and beliefs of others around us. These factors might influence the boy Performance and he cannot perform well in his assessment.
