select the best answer for the question

1. read the following paragraph and answer the question that follows.

\adding only the material needed—instead of removing unnecessary material—significantly reduces manufacturing waste. traditional manufacturing may remove up to 95 percent of raw material by the end of the process. 3d printing is far more efficient; even if a small component’s design is kept the same, printing that component will remove up to 26 times less material than traditional manufacturing would. adapting designs specifically for 3d printing can have an even more dramatic effect.\
what’s the main idea of this paragraph?

a. most small components need to be redesigned to be 3d-printed.

b. the 3d printing of small components is less efficient than the 3d printing of large components.

c. there’s no reason to create designs specifically for the 3d-printing process

d. 3d printing produces much less waste than traditional manufacturing

Explanation:

• Option A: The paragraph says "even if a small component’s design is kept the same" for 3D printing, so it's not about most small components needing redesign. Eliminate A.
• Option B: The paragraph doesn't compare 3D printing of small vs large components. Eliminate B.
• Option C: The paragraph states "Adapting designs specifically for 3D printing can have an even more dramatic effect", so C is wrong. Eliminate C.
• Option D: The paragraph emphasizes that 3D printing (adding needed material) reduces waste, and it's more efficient than traditional manufacturing (which removes much material). This matches the main idea.

Answer:

D. 3D printing produces much less waste than traditional manufacturing
