Zorluk: OrtaAuthor's Primary Purpose

Read the following passage:

Modern composite armor systems combine an ultra-hard ceramic strike face with a ductile backing material, such as ultra-high-molecular-weight polyethylene. When a high-velocity projectile strikes the ceramic exterior, the ceramic's extreme hardness blunts and fractures the penetrator, dispersing concentrated kinetic energy across a wider surface area. The remaining shattered fragments and kinetic shock are subsequently captured and absorbed by the flexible backing layers, preventing hull perforation and mitigating behind-armor blunt trauma. By leveraging the distinct physical properties of each layer, composite armor delivers superior ballistic protection while substantially reducing total system weight compared to monolithic steel plating.

Statement: The author's primary purpose in the passage is to explain how combining different material layers provides effective ballistic protection.

Cevap: Cevap

Cevap

True
The statement correctly identifies the author's primary communicative objective. The author introduces two complementary materials and details the mechanical process through which their combined interaction successfully stops high-velocity threats.

Adım Adım Çözüm

1
Analyze the overall topic and rhetorical structure of the passage.
The passage outlines the components of composite armor (ceramic strike face and ductile backing) and systematically explains the physical mechanism by which they defeat incoming projectiles.
Determining primary purpose requires evaluating the complete text's communicative goal rather than isolating a single detail.
2
Compare the synthesized purpose with the claim in the statement.
The statement claims that the purpose is to explain how combining different material layers provides effective ballistic protection, which accurately reflects the text's explanatory focus on layered material synergy.
Evaluating alignment between the statement and the overarching theme determines the truth value.
3
Verify that no secondary or incidental points represent the primary purpose.
Mentions of weight reduction and steel comparisons are secondary benefits supporting the core explanation, confirming that the statement's broad characterization is correct.
Distinguishing the central purpose from supporting details ensures the statement is unequivocally true.
