George Bernard Shaw wrote: “That any sane nation, having observed that you could provide for the supply of bread by giving bakers a pecuniary interest in baking for you, should go on to give a surgeon a pecuniary interest in cutting off your leg is enough to make one despair of political humanity.”
Shaw’s statement would best serve as an illustration in an argument criticizing which of the following?
(A) Dentists who perform unnecessary dental work in order to earn a profit
(B) Doctors who increase their profits by specializing only in diseases that affect a large percentage of the population
(C) Grocers who raise the price of food in order to increase their profit margins
(D) Oil companies that decrease the price of their oil in order to increase their market share
(E) Bakers and surgeons who earn a profit by supplying other peoples’ basic needs

It is widely assumed that a museum is helped financially when a generous patron donates a potential exhibit. In truth, however, donated objects require storage space, which is not free, and routine conservation, which is rather expensive. Therefore, such gifts exacerbate rather than lighten the demands made on a museum’s financial resources.
Which of the following, if true, most seriously weakens the argument above?
(A) To keep patrons well disposed, a museum will find it advisable to put at least some donated objects on exhibit rather than merely in storage.
(B) The people who are most likely to donate valuable objects to a museum are also the people who are most likely to make cash gifts to it.
(C) A museum cannot save money by resorting to cheap storage under less than adequate conditions, because so doing would drive up the cost of conservation.
(D) Patrons expect a museum to keep donated objects in its possession rather than to raise cash by selling them.
(E) Objects donated by a patron to a museum are often of such importance that the museum would be obliged to add them to its collection through purchase if necessary.

选E， 博物馆将其纳为自己的收藏，和财务支出有什么关系。存储，维护，的费用不一样会产生吗。

Hotco oil burners, designed to be used in asphalt plants, are so efficient that Hotco will sell one to the Clifton Asphalt plant for no payment other than the cost savings between the total amount the asphalt plant actually paid for oil using its former burner during the last two years and the total amount it will pay for oil using the Hotco burner during the next two years. On installation, the plant will make an estimated payment, which will be adjusted after two years to equal the actual cost savings.
Which of the following, if it occurred, would constitute a disadvantage for Hotco of the plan described above?
(A) Another manufacturer’s introduction to the market of a similarly efficient burner
(B) The Clifton Asphalt plant’s need for more than one new burner
(C) Very poor efficiency in the Clifton Asphalt plant’s old burner
(D) A decrease in the demand for asphalt
(E) A steady increase in the price of oil beginning soon after the new burner is installed
