I have a question about PT49.S4.Q16. If this were a sufficient assumption question, can (D) be a correct answer?

(D) says "beautiful β†’ best." "Most beautiful" are beautiful, so it would to be "Most beautiful β†’ beautiful β†’ best." (D) certainly fills the gap in the argument. But I think it's not necessary since we don't need all beautiful pieces to be the best to conclude that "beauty" and "truth" are different.

Argument Breakdown:

[[Main Argument]]

Premise: A [beauty = truth] β†’ X [most realistic (R) β†’ best (B)]
(Sentence 2: If there were no difference, then the most realistic pieces of art would be the best as well)

Premise: /X [most realistic (R) and not best (/B)]
(Sentence 3: But many of the most realistic artworks are not among the best)
β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”β€”
Conclusion: /A (beauty =/= truth)γ€€
(Sentence 1: There is a difference between beauty and truth)

[[Sub-argument]]

Premise: A [beauty = truth] β†’ C [most realistic (R)β†’ most truthful]
(Sentence 2: since the most realistic pieces are the most truthful)
A [beauty = truth] β†’ C2 [most realistic (R)β†’ most beautiful]
[[[[[GAP IN THE ARGUMENT]]]]]

Conclusion: A [beauty = truth] β†’ X [most realistic (R) β†’ best (B)]
(Sentence 2: If there were no difference, then the most realistic pieces of art would be the best as well)

[[[[[GAP IN THE ARGUMENT]]]]]
C2 (= C) β†’ X
