Explanation
Correct answer: C.
Choice C is the best answer because it presents the quotation that most effectively illustrates the claim that Echelman’s sculptures appear delicate but are in fact quite durable. The text explains that Echelman’s sculptures include flowing shapes that mimic the wind. If it is true that the materials she uses are both flexible and strong, that would help explain why the works are durable even though they appear delicate.
Why the other choices are wrong
Choice A
Choice A is incorrect because the claim in the text is not about how Echelman models her work before sculpting.
Choice B
Choice B is incorrect because the claim in the text is not about the planning and design phases of Echelman’s work.
Choice D
Choice D is incorrect because the claim in the text is not about how the sculptures relate to their locations.
