Zorluk: OrtaDistinguishing Supported and Unsupported Inferences

Aviation maintenance technicians routinely inspect aircraft composite honeycomb sandwich panels for core moisture ingress. During high-altitude flight, ambient temperatures drop significantly, creating a pressure differential that can draw atmospheric moisture into minute micro-cracks in the outer skin. When the aircraft ascends and descends repeatedly through freezing and warm conditions, trapped water undergoes continuous freeze-thaw cycles. This expansion gradually separates the composite face sheets from the internal honeycomb core, severely weakening the structural stiffness of flight control surfaces even when the exterior skin appears undamaged.

Based on the passage, which of the following conclusions is most logically supported?

  1. A
    Micro-cracks in the outer skin only develop when aircraft exceed standard operational cruise altitudes.
  2. Internal delamination can compromise a control surface's load-bearing ability before visible outer flaws appear.Cevap
  3. C
    Technicians must use ultrasonic pulse-echo testing to detect hidden moisture in honeycomb structures.
  4. D
    The physical separation of face sheets from the honeycomb core triggers atmospheric moisture to enter the structure.

Cevap

Internal delamination can compromise a control surface's load-bearing ability before visible outer flaws appear.
The conclusion that internal delamination can compromise a control surface's load-bearing ability before visible outer flaws appear is directly supported by the passage, which explicitly connects internal core separation and stiffness loss to situations where the exterior skin remains visibly intact.

Adım Adım Çözüm

1
Analyze the passage for factual statements regarding structural degradation and visible external conditions.
Identified that moisture causes freeze-thaw cycles, separating internal face sheets from the core and weakening stiffness while the exterior appears undamaged.
Establishing the direct textual evidence is necessary before evaluating candidate deductions.
2
Evaluate each conclusion against the passage evidence to distinguish supported inferences from unwarranted assumptions.
The statement regarding internal structural compromise preceding visible outer damage paraphrases the passage accurately without adding external assertions.
A valid inference must follow logically from the provided text without relying on outside knowledge, causal reversals, or unjustified constraints.
