Atheoretical perspective most popular in the mid-twentieth century held that social realities such as the roles that men and women play in heterosexual couples or the existence of inequality could be explained by the necessary purpose they served in society. what was this theoretical perspective?

Functionalism  

Explanation:

The Functionalism perspective is largely based on the work of Herbert Spencer, Emile Durkheim. According to society is interconnected par that works together in a harmonica l perspective to maintain the balance and social equilibrium for the whole. Every social institution plays a part in the function of society. Education provides to transmit the social skills, knowledge, and culture to its youth. The family provides a context to reproduce, develop, nurture and socialization. Politics provides the means to govt. policies. economics provides the production, distribution, and consumption of good services. religion provides moral guidance and an outlet for the worship of high power. It focuses on the interconnection of the part and how these part works properly in society.

the answer is true!                                          

marginal cost is a microeconomic measure that us to evaluate the extent to which the level of production of a good is sustainable in accounting, that is, to how many quantities the company plans to profit from the production of the good.

the concept of marginal cost is simple, it means the cost of producing one more item. for example, in the case of pies, the marginal cost is the cost of producing one more pie than those that have already been produced.

it is important to understand that productive activity influences marginal cost. the marginal cost of some goods can be very high, while others may be insignificant. for example, the marginal cost of producing an extra plane is very high. already the marginal cost of a water company to provide 1l more water is derisory.

in the case of pies, the cost involves the inputs, the labor and the fixed cost, which involves the fixed space of the bakery. the level of production initially has the marginal cost decreasing because there is space and manpower available. however, to produce more you have to hire more workers and buy more inputs. if physical space is limited, workers will conflict with places, inputs and their productivity will decrease, meaning there is an optimum point of production for each level of space and manpower. from this point on, the productivity of the workers will be getting smaller because of lack of space, so that the marginal cost of producing one more pie will be increasing. so, although you have not posted the chart, but if you have the answer, you can see that my explanation goes according to the marginal cost curve that will increase from the 4th pie, answer (c).
