Which president did not contribute to the progressive movement throughout the early 1900s? theodore roosevelt william howard taft warren g. harding woodrow wilson

Theodore Roosevelt 1901-1909, was known as a trust-buster, champion of the environment, consumers, and other reforms.  TR is known for the Meat Inspection Act and the Labelling Act. His progressive platform expanded when he ran again for President as an independent Progressive candidate in 1912.

William Howard Taft 1909-1913 was Roosevelt's hand-picked successor.  Although he busted more trusts than Roosevelt, Taft was more conservative.  When he fired Gifford Pinchot, Roosevelt's appointment as the head of the US Forest Service, Roosevelt broke with Taft, and ran against him, splitting the Republican Party, thus giving the election to Woodrow Wilson.

Woodrow Wilson 1913-1921 was a Democrat and a Progressive.  Unlike Roosevelt, Wilson did not believe in the concept of good trusts and bad trusts, and sought to regulate business more thoroughly.  Wilson is credited with helping to create the Federal Reserve Board, and pushing through the Clayton Anti-Trust Act of 1914.  During World War I, Wilson's administration took a more interventionist role in the economy.  Unlike Roosevelt, Wilson was only luke-warm on the issue of women's suffrage. Wilson also supported the segregation of African-Americans who were employed by the Federal Government.

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).
