Answer:
Thomas and Leanna are engaging in gender non-conformity.
Explanation:
As the name states, gender non-conforming refers to <em>not accepting gender roles</em> established by society.
Gender roles are specific behaviors, responsibilities and values attributed to each gender. This means a girl would be expected to dance ballet while a boy is expected to play football or not show his feelings too much, for example.
In this case, both Thomas and Leanna have chosen to not conform to their gender roles, doing what they want instead such as Thomas wearing a dress and Leanna having a buzzcut and swearing a lot.

<u>Marginal Costs & Marginal benefits in a choice you made.</u>
Assume that I want to buy an ornament for hands. I spend $500 for purchasing an ornament. When I was supposed to see another I wish to buy that. But spending again for the ornaments also not a good idea. I am also not willing in spending $500 for the ornament. So, I decided to go for an ornament that costed only $250. No, my marginal benefit get decreased from $500 to $250. When I decided to go fro the second one or more than one of same good my marginal benefits decrease.
Marginal cost is something that changes in a smaller range in the production of one additional unit. For example I decide to manufacture 500 pens. i need raw materials for the production and a building and machine for production. The change in the cost or expenses that happens when I decide to produce 600 pens is the marginal cost.
