Read the passage below:
During late summer operations, technicians at a grain storage facility noted a steady rise in temperature within the central core of the silo. Concurrently, fine dust settled heavily across the overhead conveyor drive motors, and condensation formed along the cooler concrete perimeter walls. By autumn, inspection logs recorded that the conveyor motors ran at diminished rotational speeds, the central grain developed localized discoloration, and the grain along the perimeter wall formed a hardened crust.
Based on the passage, match each observed facility condition on the left with its logically implied outcome on the right.
- Fine dust settling heavily across the conveyor drive motorsRestricted motor ventilation and mechanical strain causing reduced rotational speed
- Steady rise in temperature within the central grain coreThermal degradation causing localized discoloration of stored grain
- Condensation gathering along the cool concrete perimeter wallsMoisture absorption causing the formation of a hardened crust along the boundary
Answer
Dust accumulation matches with reduced motor rotational speed due to restricted ventilation; central core temperature rise matches with grain discoloration from thermal degradation; perimeter wall condensation matches with crust formation from moisture absorption.
Each observed environmental condition at the facility logically produces a specific mechanical or physical outcome: motor dust accumulation impedes thermal dissipation to slow rotation, core heat degrades grain color, and perimeter condensation induces moisture-driven surface crusting.
