Chaz is listening to his grandma reminisce about the first time she danced with his grandpa 60 years ago. when his grandma says, "it seemed like the song would play forever," chaz understands that it is more likely his grandma was listening to a radio playing and not a cd. this understanding requires chaz use a(n):

a. given-new contract.
b. age-appropriate principle.
c. garden path model.
d. instrument inference.
d. instrument inference.

D) instrument inference.

Explanation:

An inference is when you can understand something without the aid of a text. In this way, an instrument inference is when you use some tools and clues to find what you're looking for. In this case, Chaz realizes that his grandma was listening to the radio because of the way she spoke about. The feeling of eternity created by the song was because in one moment it would end, so they enjoyed as they could, creating the idea of stay there for a long time. A sensation that a CD can't provide.

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).
