Difficulty: MediumRecognizing Implied Cause and Effect

Technicians in an optical assembly room noticed microscopic surface imperfections on polished quartz lenses during a late inspection. Earlier that week, facility managers replaced the room's high-efficiency particulate air filters with high-voltage electrostatic dust precipitators. Diagnostic meters subsequently recorded elevated static electrical charges accumulating across the metal mounting fixtures where lenses were secured. Uncharged atmospheric debris in the room became polarized, clustering tightly along the contact points of the grounded polishing tables.

The passage suggests that the surface imperfections on the lenses were primarily caused by which of the following?

  1. A
    The timing of the late inspection shift conducted by optical technicians
  2. Accumulated electrical charges drawing airborne particles onto polishing contact surfacesAnswer
  3. C
    Microscopic imperfections in the quartz material that caused the precipitators to overload
  4. D
    Improper handling procedures by technicians unfamiliar with the polishing tables

Answer

Accumulated electrical charges drawing airborne particles onto polishing contact surfaces
The passage establishes that installing electrostatic precipitators led to static electrical charges on the fixtures, which in turn polarized airborne debris and gathered it at the contact points of the polishing tables. The logical conclusion is that these gathered particles scratched the lenses during polishing, causing the observed surface imperfections.

Step-by-Step Solution

1
Identify the chain of events described in the passage
Electrostatic precipitators were installed, static charges accumulated on lens mounting fixtures, and airborne debris became polarized and clustered on polishing contact points where lenses were secured.
Understanding the factual sequence allows one to identify how one event naturally triggers the next without explicit transition words.
2
Connect the accumulated debris on the polishing fixtures to the lens defects
Debris gathering directly at the lens contact points during polishing caused abrasive surface imperfections on the quartz lenses.
Deducing the unstated link between particulate accumulation at the contact points and the physical scratching of the polished surface resolves the implied cause.
