Zorluk: KolayParaphrased Fact Recognition

In commercial heating and ventilation systems, maintenance personnel monitor differential pressure gauges across large particulate air filters. When dust and debris accumulate over months of operation, resistance to airflow steadily increases, creating a measurable pressure drop between the upstream and downstream sides of the filter bank. Rather than replacing filters on an arbitrary calendar schedule, facility engineers use this pressure difference as the primary indicator for filter replacement. Installing fresh filters only when the pressure drop exceeds manufacturer thresholds minimizes unnecessary operational costs while maintaining proper indoor airflow.

According to the passage, facility technicians determine the right time to replace air filters by doing which of the following?

  1. A
    Adhering to an arbitrary calendar schedule for routine maintenance
  2. Checking the variance in air pressure between opposite sides of the filtration unitCevap
  3. C
    Waiting until airflow resistance across the filter bank decreases significantly
  4. D
    Measuring the physical weight of dust particles collected on the filter surface

Cevap

Checking the variance in air pressure between opposite sides of the filtration unit
The correct response accurately restates the passage's factual detail: facility engineers monitor the pressure drop between the upstream and downstream sides of the filter bank to decide when replacement is required, rather than relying on fixed time intervals.

Adım Adım Çözüm

1
Locate the portion of the passage describing how technicians determine when to replace filters
The text states that facility engineers use the pressure difference between upstream and downstream sides as the primary indicator for filter replacement.
Direct fact retrieval requires pinpointing the specific sentence addressing the decision criteria.
2
Evaluate the options for a paraphrase that preserves the meaning without relying on verbatim language
'Checking the variance in air pressure between opposite sides of the filtration unit' accurately restates monitoring the pressure drop across upstream and downstream sides.
Paraphrased fact questions test the ability to recognize identical concepts expressed through alternative vocabulary and sentence structure.
