The fossil remains of Sinosauropteryx dinosaur recently discovered in China had a thin layer of outline around its skeletal structure suggesting that it had feathers. But critics state that the most common function of the feathers is to enable flight or to provide insulation. Since flight was not possible because of the enormous structure and weight of the dinosaur and insulation was not possible because of the outline’s position, the outline was not that of feathers but rather of frills.

Which of the following, if true, would, together with the information above, provide the best basis for the claim that the layer of outline is the fossil remains of feathers?


(A) There were many other Sinosauropteryx fossils found in Germany that also had the same thin layer of outline.

(B) Apart from the above discovery, many scientists believed that Protarchaeopteryx belonging to the same genera as that of Sinosauropteryx had feathers.

(C) Many carvings depicting flying dinosaurs especially with structures such as those of Sinosauropteryx were discovered recently.

(D) In many animal fossils, fiber from skin tissues form a thin layer of outline around its skeletal structure.

(E) The chemical composition revealed that the outline was made of white and orange colors, strongly suggesting the display function of feathers as in peacocks.

Confused between A and C but C seems more correct. I think C is the answer.

I choose option E.

finding many fossils in germany does not implicate that Sinosauropteryx had feathers. Option A is out
Having similar genera feathered dinosaur does not imply that Sinosauropteryx would have them too. Option B is not a strenghtener either.
Carvings might imply that Sinosauropteryx had feathers, but it was the carving of the similar structure, we can not be sure of this option.
D does not strengthen.
Option E might do though, we know that peacocks don't fly, they only glide and the main purpose of their feathers is "display", as this possibility is not ruled out by the opposition, this might strengthen the argument.

(A) There were many other Sinosauropteryx fossils found in Germany that also had the same thin layer of outline. This is not correct, as a mere increase in fossil does not strengthen the claim.

(B) Apart from the above discovery, many scientists believed that Protarchaeopteryx belonging to the same genera as that of Sinosauropteryx had feathers. This is not correct, Protrachaeoptery could be a much small and lighter dinosaur supporting flight, however that does not necessarily apply to any other belonging to the same genera.

(C) Many carvings depicting flying dinosaurs especially with structures such as those of Sinosauropteryx were discovered recently. This is not correct, this is a confusing option however it contradicts what is directly stated in the paragraph. That, - "flight was not possible because of the enormous structure and weight of the dinosaur", therefore this is not correct.

(D) In many animal fossils, fiber from skin tissues form a thin layer of outline around its skeletal structure. This is not correct, irrelevant to the current context.

(E) The chemical composition revealed that the outline was made of white and orange colors, strongly suggesting the display function of feathers as in peacocks. This is correct, as it supports the theory that Sinosauropteryx could have had feathers, as it does not take into account either of the functions listed in the paragraph and lists an entirely different one thereby supporting the claim.
