Restorer: The amber in the Cremona ground is not what gives those instruments their depth of colour, as the books have it. Amber darkens with age in any medium, and would have darkened as much on a modern back. What the amber does is refuse to sink into the maple, and it is the film standing proud of the grain, rather than anything in the amber itself, that the eye reads as depth.

Which one of the following is an assumption required by the restorer's argument?

AA varnish film left standing on the surface of the maple need not look to the eye the same as one that has soaked down into the grain.

BThe eye is a better judge of the depth of a varnished surface than any instrument yet devised, and will remain so however far such instruments are improved.

CAny varnish that refuses to sink into maple will give the instrument it is laid on the depth of colour for which the Cremona instruments have been admired, whatever else has gone into the ground.

DThe makers who used the Cremona ground chose amber for the way they had seen it sit on the surface rather than for the colour it takes on with age.

EModern backs varnished with amber are admired for their depth of colour far less than the Cremona instruments are.
