Difficulty: MediumParagraph Summarization

Read the passage below:

Compressed air systems in heavy transport vehicles rely on inline desiccant air dryers installed between the compressor and reservoir tanks. As ambient air is compressed, its relative humidity rises, causing moisture and oil aerosols to condense within pneumatic lines. If left unchecked, this water accumulates in brake valves, corroding internal return springs and freezing during sub-zero operations, which can lead to catastrophic brake failure. The desiccant cartridge traps water vapor through molecular adsorption before air enters storage tanks, while an automatic purge valve ejects collected contaminants during governor cutout cycles.

Statement: The passage primarily explains how inline desiccant air dryers protect vehicle pneumatic brake systems by removing harmful moisture and contaminants before the air reaches storage reservoirs.

Answer: Answer

Answer

True
The proposed statement correctly identifies both the core function of the equipment (desiccant air dryers filtering moisture and contaminants) and the overarching purpose described in the text (preventing brake valve corrosion, freezing, and system failure).

Step-by-Step Solution

1
Analyze the passage to identify the central topic and overarching objective.
The text discusses how compressed air systems generate destructive moisture and how inline desiccant air dryers eliminate this hazard before air storage.
Effective paragraph summarization requires capturing both the underlying problem and the primary mechanism addressed in the text.
2
Evaluate the proposed summary statement against the full scope of the passage.
The statement encompasses the entire mechanism (removing moisture/contaminants before storage) and its primary purpose (protecting the braking system from failures like corrosion and freezing).
A valid summary must accurately represent the paragraph's complete thesis rather than overextending or narrowing down to a single supporting detail.
3
Determine the truth value of the proposed statement.
The statement is an accurate and complete summary of the passage.
Because the statement correctly encapsulates the main idea without introducing unsupported claims, the correct answer is True.
