Read the passage below:
Technicians at an automated grain silo complex observed elevated moisture readings near the concrete base walls following heavy autumn rains. Maintenance crews responded by replacing the exhaust fans along the metal roofline with higher-capacity blowers rather than inspecting the perimeter foundation drainage lines. During the subsequent storage cycle, mold colonies rapidly expanded across the bottom three feet of grain bins, while the upper grain levels remained completely dry.
True or False: The passage implies that the mold growth at the bottom of the bins persisted because the maintenance action failed to address the ground-level source of moisture.
Answer: Answer
Answer
True
The passage establishes that moisture entered at the concrete foundation after rainstorms and that mold subsequently formed only at the bottom three feet of the bins. Because the maintenance crew focused solely on rooftop exhaust fans without checking the foundation drainage, the base moisture remained unmitigated, logically leading to the localized mold growth.
