Difficulty: MediumParaphrased Fact Recognition

Read the passage below:

Industrial desiccant dehumidifiers regulate ambient humidity by passing moist process air through a continuously rotating honeycomb wheel coated with silica gel. As the airflow traverses the matrix, the desiccant adsorbs water vapor directly from the air without requiring condensation. Simultaneously, a separate, heated stream known as reactivation air flows through a designated sector of the wheel in the opposite direction. This thermal energy drives off the trapped moisture and discharges it outdoors as humid exhaust, continuously restoring the silica gel's capacity to absorb moisture before that segment rotates back into the main process airflow.

Based on the passage, determine whether the following statement is true or false:

The moisture-holding capability of the desiccant rotor is regenerated by directing an elevated-temperature airflow through the matrix to expel collected water vapor.

Answer: Answer

Answer

True
The statement is true because it accurately restates the passage's explanation of how thermal energy from the reactivation air stream removes retained moisture and renews the desiccant's operational capacity.

Step-by-Step Solution

1
Locate the portion of the passage describing how the desiccant wheel maintains or renews its operating capacity.
Identified the sentence: 'This thermal energy drives off the trapped moisture and discharges it outdoors as humid exhaust, continuously restoring the silica gel's capacity to absorb moisture...'
The statement asserts a specific factual claim regarding how the rotor is restored to hold moisture.
2
Map the phrasing and synonyms of the statement against the source text.
'Moisture-holding capability' maps to 'capacity to absorb moisture'; 'regenerated' maps to 'restoring'; 'elevated-temperature airflow' maps to 'heated stream known as reactivation air'; 'expel collected water vapor' maps to 'drives off the trapped moisture and discharges it'.
Paraphrased fact recognition requires verifying semantic equivalence without expecting identical verbatim vocabulary.
3
Determine if any factual distortion, causal inversion, or unsupported addition exists in the assertion.
The statement is completely consistent with the text and introduces no contradictions.
Ensures the truth value is unequivocal under strict reading comprehension criteria.
