On august 24, in the year 79 ce, the sky in pompeii, italy, grew dark and ominous. an orange glow illuminated the blackened sky. when the city? s residents heard the first of what would be a terrifying series of earth-shaking rumbles, they looked to mount vesuvius, six kilometers in the distance. a pillar of gray ash was pouring from the volcano? s gaping mouth. the residents of pompeii were caught by surprise. many of those who noticed the impending eruption grabbed their family members and their valuables and fled the city. as you can see from the picture, not everyone was so lucky. with what tone would you read the narrative if you wanted to read it as if you were there? a. angry c. silly b. urgent d. uncaring

B. Urgent.

Explanation:

The passage tells the scene when the volcano at Mount Vesuvius erupted, leading to the residents frantically gathering their family members and looking for safer places. So, when reading this passage, we can be sure of the rush the people will be in. There is no way this tone can be an angry one, nor can it be silly or uncaring. If one were to read it as a silly or uncaring passage, then it is obvious that that person has no humanity in him/her. the only possible tone the narrative can be read with is an urgent one.

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).
