Bunuel
An artist who sells her paintings for a fixed price decides that she must increase her income. Because she does not believe that customers will pay more for her paintings, she decides to cut costs by using cheaper paints and canvases. She expects that, by cutting costs, she will increase her profit margin per painting and thus increase her annual net income.
Which of the following, if true, most weakens the argument above?
(A) Other area artists charge more for their paintings than the artist charges for hers.
(B) The artist has failed to consider other options, such as renting cheaper studio space.
(C) The artist’s plan will result in the production of inferior paintings which, in turn, will cause a reduction in sales.
(D) If the economy were to enter a period of inflation, the artist’s projected increase in income could be wiped out by increases in the price of art supplies.
(E) The artist considered trying to complete paintings more quickly and thus increase production, but concluded that it would be impossible.

C To weaken an argument, look first at its conclusion. This argument concludes that the artist will increase her profit margin ... and thus increase her annual income by using cheaper art supplies. Which answer choice undercuts this conclusion? Choice C does; if the artist’s sales decrease, then her increased profit margin may not lead to an increase in annual income, because the decrease in sales may offset the increase in per-painting profit. The best answer is C.
