(A) Roman artisans were influenced by their Greek predecessors and often translated designs of Greek carvings into Roman designs
Out of scope.
(C) Visual aids were not available until the thirteenth century, when Roger Bacon invented eyeglasses
(D) Artisans today are unable to reproduce the carvings of ancient Roman artisans without the aid of high- powered lenses, first produced in the thirteenth century
Irrelevant. If anything, strengthens the argument.
(B) Farsighted individuals are less able than those with ordinary vision to identify objects that are at a close distance to them.
The passage mentions that the artisans did intricate work 'from a distance' so it doesn't matter how good vision was for close distances.
(E) The eyesight of farsighted individuals and those with ordinary vision is not significantly different if the objects viewed are more than a few feet away
Correct answer. Weakens the argument by saying that there is no difference in vision quality between farsighted and ordinary people if the objects are at a distance. So the researchers argument that farsightedness enabled the artisans to do intricate work from a distance is false.
