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.

]Some museum directors believe that "paint is the most sensitive substance in these works." If that is indeed the case, then think about how those directors would respond to the lab tests. They would say, "Well, the paint is not sensitive to temp and humidity. Since the paint is the most sensitive substance, then NO substance in the paintings should be sensitive to temp and humidity. In that case, why waste money (energy costs) regulating the temp and humidity?
Is there a typo error in above and correct version should be:
They (museum directors) would say, "Well, the paint is sensitive to temp and humidity.My reasoning: the inherent property of oil paint makes
my deterioration of paints less susceptible to weather changes and hence no energy costs are needed to regulate external temp and humidity.
Usually in bold face we link opinions of different characters in argument to author's opinion.
Here I am unable to link lab test results to music directors's judgement.

The passage outlines a position taken by some museum directors (MD)- according to which, since paint is the leastsensitive and can withstand changes, changes in temperature can be made, and then calls that position into question - since Gesso may actually be more sensitive. Thus, the first BF (paint is the most sensitive) is a judgement that has been offered in support of the position that the argument calls into question, and the second (changes in humidity can be made is that position.
Do not MD take the position that paint is most sensitive?
