Difficulty: EasyDrawing Logical Conclusions

Read the following passage:

Cleanroom facilities maintain higher internal air pressure than adjacent hallways to prevent airborne dust and microbes from entering through opened access doors. When the internal air pressure drops to match the hallway pressure, the protective barrier is lost, and the monitoring system activates a warning indicator to signal that outside particles can now enter the sterile work area.

Statement: Based on the passage, a cleanroom whose internal air pressure equals the hallway air pressure is vulnerable to particle contamination.

Answer: Answer

Answer

True, because equal air pressure between the cleanroom and hallway removes the protective barrier against incoming airborne particles.
The conclusion is logically supported by the passage text, which links higher internal pressure to contamination prevention and states that equalizing pressure allows outside particles to enter.

Step-by-Step Solution

1
Identify the primary mechanism used to keep contaminants out of the cleanroom.
The facility maintains higher internal air pressure relative to the hallway to block dust and microbes.
Establishing the functional purpose of the pressure difference provides the baseline premise.
2
Analyze what occurs when internal pressure equals hallway pressure.
The protective barrier is lost and outside particles can freely enter the sterile area.
Connecting the loss of pressure differential to contaminant entry determines the condition of the room.
3
Evaluate whether the statement accurately reflects this cause-and-effect relationship.
The statement that the room is vulnerable to particle contamination is a direct logical deduction from the passage.
Comparing the statement directly against the deduced condition verifies its validity as true.
