Zorluk: KolayDrawing Logical Conclusions

Before operating the hydraulic lift in the maintenance depot, technicians must verify that the safety locking bar is disengaged and the emergency release valve is closed. If the reservoir fluid falls below the minimum line, the pump will automatically shut down to prevent motor burnout. During a routine inspection, a technician observes that the hydraulic pump suddenly stops running even though electrical power remains fully supplied to the unit.

Which conclusion is most logically supported by the passage?

  1. A
    The safety locking bar engaged and cut off the building's electrical power.
  2. The hydraulic fluid level in the reservoir fell below the minimum line.Cevap
  3. C
    The pump motor burned out as a result of prolonged electrical overload.
  4. D
    The technician forgot to open the emergency release valve before starting the lift.

Cevap

The hydraulic fluid level in the reservoir fell below the minimum line.
The passage directly establishes that the pump shuts down automatically if the reservoir fluid drops below the minimum line. Because the pump ceased operating while electrical power was still active, deducing that the fluid fell below the minimum line is directly and logically supported.

Adım Adım Çözüm

1
Identify the observed condition stated in the passage.
The hydraulic pump stopped running suddenly while electrical power was still active.
Establishing the premise guides what causes a shutdown under normal electrical supply.
2
Connect the stated cause-and-effect rule to the observation.
The text specifies that the pump automatically shuts down whenever reservoir fluid falls below the minimum line.
Connecting the rule to the observation allows for a direct, valid deduction.
3
Deduce the most logical conclusion supported by the text.
The shutdown was triggered by the reservoir fluid level dropping below the minimum threshold.
This is the only shutdown trigger described in the text that matches the scenario.
