Zorluk: OrtaParaphrased Fact Recognition

Commercial aircraft landing gear assemblies utilize dry nitrogen gas rather than compressed atmospheric air to inflate their multi-ply tires. Because ambient atmospheric air contains variable amounts of moisture, extreme temperature drops at high flight altitudes can cause entrained water vapor to freeze into ice crystals, potentially jamming inflation valves during descent. Furthermore, nitrogen is chemically inert and non-flammable, which prevents explosive tire ruptures caused by intense heat radiating from brake rotors during aborted takeoffs. By excluding both oxygen and humidity from the tire casing, maintenance technicians also diminish internal rubber oxidation, thereby extending the structural lifespan of the tire.

According to the passage, which of the following is a primary benefit of using nitrogen instead of atmospheric air in aircraft tires?

  1. A
    It causes entrained water vapor to freeze into ice crystals during descent.
  2. It prevents the internal deterioration of the tire carcass to prolong its service life.Cevap
  3. C
    It cools glowing brake rotors by absorbing intense thermal energy during aborted takeoffs.
  4. D
    It delivers superior shock absorption to cushion the aircraft's impact upon landing.

Cevap

Using nitrogen prevents the internal deterioration of the tire carcass to prolong its service life.
The correct response restates the passage's concluding sentence ('diminish internal rubber oxidation, thereby extending the structural lifespan of the tire') using accurate synonyms and altered phrasing ('prevents the internal deterioration of the tire carcass to prolong its service life').

Adım Adım Çözüm

1
Locate the factual details in the text regarding the benefits of nitrogen over atmospheric air.
Identified three explicit benefits: preventing valve freeze-up from moisture, resisting ignition from hot brakes, and diminishing internal rubber oxidation to extend lifespan.
Establishing the complete set of factual claims ensures accurate verification against answer options.
2
Evaluate the answer choices for an accurate paraphrase rather than a verbatim trap.
The statement regarding preventing internal deterioration of the tire carcass directly matches 'diminish internal rubber oxidation, thereby extending the structural lifespan of the tire' using synonyms ('deterioration' for 'oxidation', 'carcass' for 'casing', 'prolong its service life' for 'extending the structural lifespan').
Paraphrased fact recognition requires identifying identical factual meaning expressed through restructured syntax and synonymous vocabulary.
