Quinn has displayed Sir John's DNA, which quinn called as "Conceptual Portrait" of Sir John. C argues that in order to call something a portrait , that something must bear some recognizable resemblance with the subject.
A is not agreeing with C. According to A, the Quinn's 'Conceptual Portrait' is a realistic portrait as it (DNA) holds the instructions to replicate Sir John. So the DNA or the conceptual portrait of sir john do resembles with sir john and thus it's right to call the DNA as portrait.
So dialogue is about whether the DNA of sir John's be called Conceptual Portrait of sir john?
QS: The dialogue provides most support for the claim that Carolyn and Arnold disagree over whether the object described by Quinn as a conceptual portrait of Sir John Sulston
1) claim that Carolyn and Arnold disagree---That DNA should be called portrait or not.
The
dialogue provide most support to which of the following?
(A) should be considered to be art
--Far fetched option. Out.
(B) should be considered to be Quinn’s work
-- whether the object (DNA) should be considered as Quinn's work??
(C) bears a recognizable resemblance to Sulston
--DNA bears a recognizable resemblance to Sulston. This is A's view.
(D) contains instructions according to which Sulston was created
--DNA contains instructions according to which Sulston was created. Again A's view.
(E) DNA is actually a portrait of Sulston
--This was the actual point of discussion. Correct.
Note: The dialogue wasn't supporting anything. It was just POV of C and A. There was no logical conclusion of the dialogue. So, if we want to support the dialogue then we should support the point on which the dialogue was based. i.e "whether the DNA of sir John's be called Conceptual Portrait of sir john". Hence option E is correct.
