One of the greatest barriers to problem-solving is accurately defining the problem. To help get a grip on the situation, the author suggests three strategies that the critical thinker would use to identify the problem. What is one of those strategies?

view the problem from different perspectives

Explanation:

Every human has to face problems in their life. It is a part of of everybody's life. Understanding the problem and fighting against the problem decides the person ability to live their life.

The author speaks that people's greatest barrier or failure to solve problem is that they lack defining the problem accurately. Once people learns to define their problem accurately form all perspectives, they will be successful in solving their problems in life.

The author also suggest that there are three different strategies that a critical thinker may use to properly identify a problem. One such strategy is one needs to look at their problems from all possible and different perspectives so as to properly identify them and find out an easy solution for them. Doing this will help people to get a clarity o the  problem and it will give them courage to find a solution to it.

Looking from different perspective will provide an idea that every problem is not as big as it looks like at the beginning and with this strategy one can find a solution to the problem.

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).
