Museums that house Renaissance oil paintings typically store them in environments that are carefully kept within narrow margins of temperature and humidity to inhibit any deterioration. Laboratory tests have shown that the kind of oil paint used in these paintings actually adjusts to climatic changes quite well. If, as some museum directors believe, paint is the most sensitive substance in these works, then by relaxing the standards for temperature and humidity control, museums can reduce energy costs without risking damage to these paintings. Museums would be rash to relax those standards, however, since results of preliminary tests indicate that gesso, a compound routinely used by Renaissance artists to help paint adhere to the canvas, is unable to withstand significant variations in humidity.
In the argument above, the two portions in boldface play which of the following roles?

Inthe argument above, the two portions in boldface play which of the followingroles? A. The first is an objection that has beenraised against the position taken by the argument; the second is the positiontaken by the argument. B. The first is the position taken by theargument; the second is the position that the argument calls into question. C. The first is a judgment that has beenoffered in support of the position that the argument calls into question; thesecond is a circumstance on which that judgment is, in part based. D. The first is a judgment that has beenoffered in support of the position that the argument calls into question; thesecond is that position. E. The first is a claim that the argument callsinto question; the second is the position taken by the argument.
The directors thought that 1) the paint can adjust; 2) the paint is the most sensitive to humidity; 3) if the most sensitive component can adjust, the whole painting is safe; and 4) let's relax the standard!
What the director missed is that something else other than the paint is very sensitive to humidity change. Thus the standard should not be relaxed.
此题主要是看到On THE BASIS OF THAT paint is the mostsensitive substance in these works, WE COULD REACH THE CONCLUSION OR POSITION museums can reduce energy costs withoutrisking damage to these paintings
即只要保护了paint就可以降低成本了。 但是这个position是错误的,要被call into question.
