<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.

They show that biological differences between males and females can sometimes be the result of social differences, rather than their cause                 
Explanation:              
Social difference: The term social difference is determined as different situations in which different people are being discriminated against with each other based on racial, social, and economic inequality. It includes language, caste, race, color, sexual orientation, social class, etc. A few social differences arise because different people choose to follow or implement specific practices.
The social difference can be a result of the biological difference between females and males in a particular society as there are different norms, rules or regulations are being set for different genders.
