Question

12th grade post - assessment
5 that may soon change with advances in whats called \large - scale additive manufacturing.\
not since the adoption of the steel frame has there been a development with as much
potential to transform the way buildings are conceived and constructed.
large - scale additive manufacturing, like desktop 3d printing, involves building objects one
layer at a time. whether its clay, concrete, or plastic, the print material is extruded in a fluid
state and hardens into its final form.
as director of the institute for smart structures at the university of tennessee, ive been
fortunate to work on a series of projects that deploy this new technology.
while some roadblocks to the widespread adoption of this technology still exist, i can
foresee a future in which buildings are built entirely from recycled materials or materials
sourced on - site, with forms inspired by the geometries of nature.
promising prototypes
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 structures thin, double - curved surfaces were inspired by the petals of its namesake
flower.

question 15
which word is closest in meaning to \extruded\ as it is used
in paragraph 6?
a. collected
b. enhanced
c. produced
d. strengthened

Explanation:

To determine the closest meaning of "extruded" in the context, we analyze the sentence: "the print material is extruded in a fluid state and hardens into its final form". The process described involves the material being pushed out (like in 3D printing or manufacturing) to form the object.

• Option A "collected" implies gathering, not matching the manufacturing process here.
• Option B "enhanced" means improving, which is not related to the material's physical process.
• Option C "produced" in the sense of being formed or pushed out (as in manufacturing) aligns with the idea of extruding (pushing out the fluid material to build layers).
• Option D "strengthened" refers to making stronger, not related to the extrusion process.

So "produced" is the closest in meaning.

Answer:

C. produced
