Three-year-old Brian is playing with his 5-year-old sister Allison, who becomes frustrated that her books fell down while they were playing library. Allison begins to cry, and Brian laughs at Allison. This could BEST be described as:
A. normal behavior because of Brian's age.
B. kind, tender behavior masked as non-helpful behavior.
C. abnormal behavior because Brian is lacking empathy.
D. aggressive behavior.

Explanation:

There is a lot of discussion surrounding a child's ability to develop empathy. Some parents show concern when their three-year-old kids do not seem as responsive to other children's feelings as they expected. However, even though we are born with the capacity for empathy, it is developed throughout childhood and adolescence.

Empathy can be basically defined as the ability of putting yourself in someone else's shoes. Brian is, however, too young to comprehend all types of feelings. He is also too young to understand that laughing is not exactly an appropriate reaction to someone crying. This understanding is still to come - either naturally, or via teaching. With time, he will grow more conscious of what his peers are feeling and of what he should feel in his turn. He will eventually learn to help and comfort those cry, for instance.

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).
