Renaissance oil paintings deteriorate problem.

Expert replies
by amysky_0205 » Wed Dec 05, 2012 7:59 pm
Art restorers who have been studying the factors that cause Renaissance oil paintings to deteriorate physically when subject to climatic changes have found that the oil paint used in these paintings actually adjusts to these changes well. The restorers therefore hypothesize that it is a layer of material called gesso, which is under the paint, that causes the deterioration.

Which of the following, if true , most strongly supports the restorers' hypothesis?

A.Renaissance oil paintings with a thin layer of gesso are less likely to show deterioration in response to climatic changes than those with a thicker layer.

B.Renaissance oil paintings are often painted on wooden panels, which swell when humidity increases and contract when it declines.

C.Oil paint expands and contracts readily in response to changes in temperature, but it absorbs little water and so is little affected by changes in humidity.

D.An especially hard and nonabsorbent type of gesso was the raw material for moldings on the frames of Renaissance oil paintings.

E.Gesso layers applied by Renaissance painters typically consisted of a coarse base layer onto which several increasingly fine-grained layers were applied.

OA: A

can someone explain why the OA supports and E didn't support

E only tells us that many layers of gesso of varying thickness were applied. It does not talk about what impact these layers would have had in the oveall response of the oil painting to the climatic change.

On the other hand as per A,
a thin layer of gesso => less likely to show deterioration in response to climatic changes
a thicker layer of gesso => more likely to show deterioration in response to climatic changes

So the more the application of gesso the more the deterioration in response to climatic changes.
