Difficulty: EasyInferring Author Purpose and Intent

Read the following passage:

Commercial and military aircraft tires are inflated almost exclusively with dry nitrogen gas rather than standard compressed ambient air. Unlike ambient air, which contains significant water vapor and oxygen, pure nitrogen maintains a stable pressure under extreme temperature swings experienced during high-altitude flight and high-speed landings. Furthermore, nitrogen prevents oxidation of the inner rubber lining and eliminates the risk of internal tire combustion caused by intense braking heat. Standard air compressors are strictly prohibited for primary aircraft tire servicing.

Statement: The author wrote this passage primarily to explain why aviation maintenance standards mandate the use of nitrogen over ambient air for tire inflation.

Answer: Answer

Answer

True
The statement accurately identifies the author's primary purpose. Throughout the passage, the author systematically explains the scientific and mechanical reasons why nitrogen is preferred and required over compressed ambient air.

Step-by-Step Solution

1
Analyze the passage to identify the central topic and supporting points.
The text discusses aircraft tires, comparing nitrogen and ambient air across multiple operational criteria such as thermal stability, rubber preservation, and fire prevention.
Determining what information the author highlights helps uncover the overarching communicative intent.
2
Evaluate the author's primary goal in presenting these comparisons.
The author provides technical justifications that explain why nitrogen is standard and why ambient air compressors are prohibited.
Inferring purpose requires distinguishing between individual technical details and the primary motivation behind writing the text.
3
Compare the inferred purpose to the provided statement.
The statement accurately reflects the author's primary purpose of explaining the rationale behind using nitrogen in aircraft tires.
Confirming alignment between the passage's intent and the statement establishes that the statement is true.
