Zorluk: KolayInference and Logical Deduction

Passage:
In several semi-arid districts, the local administration mandated the adoption of solar-powered drip irrigation systems for smallholder farms to conserve groundwater. Over a two-year period, water table depletion rates in these districts dropped by fifteen percent. However, overall agricultural energy consumption increased because farmers utilized the surplus electricity generated by the solar panels during non-irrigation hours to run small-scale food processing machinery.

Which of the following logically follows from the passage above?

  1. The implementation of solar-powered drip irrigation was accompanied by an increase in farm energy use for activities other than irrigation.Cevap
  2. B
    Solar-powered irrigation systems are financially unviable for smallholder farmers without continuous government subsidies.
  3. C
    Groundwater conservation in semi-arid regions is impossible unless overall farm electricity consumption is reduced.
  4. D
    The administrative mandate failed to bring about any reduction in groundwater depletion rates over the two-year period.

Cevap

The implementation of solar-powered drip irrigation was accompanied by an increase in farm energy use for activities other than irrigation.
The correct answer directly restates a logical conclusion from the text: surplus solar power was used to run food processing equipment, resulting in an increase in energy use beyond irrigation.

Adım Adım Çözüm

1
Analyze the facts stated in the passage
The passage establishes two key facts: (1) groundwater depletion dropped by 15% following solar drip irrigation adoption, and (2) overall agricultural energy consumption rose because farmers used extra solar power during off-hours for food processing machinery.
Inference questions require relying strictly on facts given in the text.
2
Evaluate the logical necessity of the correct statement
Since the passage states that energy consumption increased specifically due to running food processing machinery during non-irrigation hours, it logically follows that farm energy usage increased for non-irrigation purposes.
A valid inference must be a direct, unavoidable logical conclusion derived from the passage text.
