Zorluk: OrtaRecognizing Implied Cause and Effect

Read the passage below:

During an autumn inspection of an upland hydroelectric station, operators recorded an unexpected decline in generator turbine output following a week of severe mountain windstorms. Field technicians examining the facility observed that the submerged steel trash racks at the reservoir forebay were blanketed by dense layers of uprooted brush and pine needles. Downstream pressure gauges along the main penstocks registered unusually low hydraulic head levels despite full reservoir capacity.

Based on the passage, the decline in electrical generation was initiated by storm debris restricting the volume of water entering the penstocks.

Cevap: Cevap

Cevap

True. The passage implies that storm-blown debris blocked the intake racks, restricting water flow and reducing generator output.
The correct evaluation is True because the passage presents a sequence where storm debris gathered on intake grates, downstream pressure plummeted, and turbine power fell despite ample reservoir volume, clearly implying that intake blockage caused the generation deficit.

Adım Adım Çözüm

1
Analyze the sequence of events and observations in the passage
Identified windstorms, debris accumulation on submerged intake racks, low penstock pressure, and declining generator output despite a full reservoir.
Synthesizing individual factual observations is required to determine the underlying causal chain without explicit transition words.
2
Deduce the unstated causal link between the physical blockage and the operational deficit
Debris on the trash racks physically impeded water flow into the penstocks, lowering hydraulic pressure and reducing the force driving the turbines.
Connecting the intake obstruction to the pressure drop explains the loss of power generation logically.
3
Evaluate the accuracy of the provided statement against the deduced causal chain
The statement accurately reflects the unstated cause of the reduced turbine output.
Confirming the validity of the causal inference determines the final true/false classification.
