Question

among these projects is the trillium pavilion, an open - air structure printed from recycled abs polymer, a common plastic used in a wide range of consumer products. 10 the structure’s thin, double - curved surfaces were inspired by the petals of its namesake flower. the project was designed by students, printed by loci robotics, and constructed at the university of tennessee research park at cherokee farm. other recent examples of large - scale additive manufacturing include tecla, a 450 - square - foot prototype dwelling designed by mario cucinella architects and printed in massa lombarda, a small town in italy. the architects printed tecla out of clay sourced from a local river. the unique combination of this inexpensive material and radial geometry created an energy - efficient form of alternative housing. back in the u.s., the architecture firm lake flato partnered with the construction technology firm icon to print concrete exterior walls for a home dubbed “house zero” in austin, texas. the 2,000 - square - foot home demonstrates the speed and efficiency of 3d - printed concrete, and the structure displays a pleasing contrast between its curvilinear walls and its exposed timber frame. assessment questions how do paragraphs 9 - 14 contribute to the development of ideas in the text? a. by explaining the process of using large - scale additive manufacturing in construction b. by describing examples of structures that have used large - scale additive manufacturing c. by highlighting the benefits and disadvantages of the structures created with large - scale additive manufacturing d. by comparing structures built with large - scale additive manufacturing versus mass - produced materials

Explanation:

To solve this, we analyze each option:

• Option A: The paragraphs don't focus on explaining the process of using large - scale additive manufacturing in construction. They are more about giving examples of structures.
• Option B: Paragraphs 9 - 14 describe multiple structures (Trillium Pavilion, Tecla, House Zero) that used large - scale additive manufacturing. This matches the content of these paragraphs.
• Option C: There is no discussion of disadvantages of the structures created with large - scale additive manufacturing in these paragraphs.
• Option D: There is no comparison between structures built with large - scale additive manufacturing and mass - produced materials.

Answer:

B. by describing examples of structures that have used large - scale additive manufacturing
