Cultural Capital

The ability to deal with bureaucracies and confidence in public social settings allow Liam’s parents to be actively involved in the Parent Teacher Association at his school. These traits are an example of cultural capital.

The reason why "cultural capital" would be the correct answer because the traits that Liam's parents are doing around public social settings and bureaucracies to be involved with the Parent Teacher Association represents cultural capital.

Cultural capital is is gifts that someone has socially to allow them to be mobile  in a social manner, specifically in a "classified" society.

In this case, Liam's parents would be classified as Liam's parents to the school. However, since they're able to be strong in social traits with bureaucracies and social settings, they're able to become part of the Parent Teacher Association Program, which allows them to better socialize with Liam's teacher(s).

just don't strip down in public lol
