Caroly says that the portrait Quinn shows is the replicated of Sir John's portrait. Therefore, he says that some characteristics of the replicated portrait is the same as Sir John's portrait. But Arnold says that it is not Quinn work rather it is the original work ( Sir John portrait) because most of the characteristics of Quinn's portrait is the same as Sir John's portrait. Therefore, form the two statements we can not conclude that the portrait Quinn shows is actually a portrait of Quinn or the portrait is actual work of Sir John.

I marked C here. Can someone explain a little bit more about the answer?

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.

Carolyn: The artist Marc Quinn has displayed, behind a glass plate, biologically replicated fragments of Sir John Sulston’s DNA, calling it a “conceptual portrait” of Sulston. But to be a portrait, something must bear a recognizable resemblance to its subject.

Arnold: I disagree. Quinn’s conceptual portrait is a maximally realistic portrait, for it holds actual instructions according to which Sulston was created.

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

(A) should be considered to be art X
-no evidence of this
(B) should be considered to be Quinn’s work X
-no evidence of this
(C) bears a recognizable resemblance to Sulston X
-tempting trap choice, the reality is Arnold doesn't actually attack this claim by Carolyn at all. What he is attacking is Carolyn's conclusion that Sulston's DNA art piece IS NOT a portrait. This is made clear here: "I disagree. Quinn’s conceptual portrait is a maximally realistic portrait,"
(D) contains instructions according to which Sulston was created X
-We don't know whether Carolyn disagrees with Arnold on this ...never mentioned
(E) is actually a portrait of Sulston CORRECT

The video clarified all doubts.
Thanks!

(A) should be considered to be art
They are definitely not contesting whether it's an art , they unserstand however the question they are raising what it's


(B) should be considered to be Quinn’s work
They are on the same page as of wjose work it's


(C) bears a recognizable resemblance to Sulston
IT was just raised by A not B alone hence it's like considering one side of the argument


(D) contains instructions according to which Sulston was created
yes this is only addressing the second speakers argument

(E) is actually a portrait of Sulston
Yes this is what they are most having a difference in hence IMO E

It boils down to a question of what both agree.

And both agree that it's a portrait.
