Zorluk: OrtaDrawing Inferences and Valid Conclusions

Between 2018 and 2024, all commercial solar farms in Country X that integrated lithium-iron-phosphate (LFP) battery storage systems achieved continuous grid synchronization during peak demand hours. Conversely, no solar farm relying exclusively on nickel-manganese-cobalt (NMC) storage maintained uninterrupted grid connectivity throughout those same peak periods. During this six-year period, any solar farm in Country X that failed to maintain continuous grid synchronization during peak demand hours was assessed a regulatory surcharge. Furthermore, every commercial solar farm built in Country X after 2020 integrated either LFP or NMC storage systems, but never both.

Based on the information provided, which of the following statements must be logically true? Select all that apply.

  1. Every commercial solar farm in Country X relying exclusively on NMC battery storage between 2018 and 2024 was assessed a regulatory surcharge.Cevap
  2. B
    Commercial solar farms using NMC battery storage generated less total electricity than those using LFP battery storage.
  3. Any commercial solar farm built in Country X in 2022 that integrated LFP storage achieved continuous grid synchronization during peak demand hours.Cevap
  4. D
    Integrating LFP battery storage was the sole method available for solar farms in Country X to avoid regulatory surcharges.
  5. E
    Any solar farm in Country X assessed a regulatory surcharge between 2018 and 2024 must have utilized an NMC battery storage system.

Cevap

The correct statements are that every commercial solar farm relying exclusively on NMC battery storage between 2018 and 2024 was assessed a regulatory surcharge, and that any commercial solar farm built in 2022 that integrated LFP storage achieved continuous grid synchronization during peak demand hours.
The statement regarding exclusive NMC storage farms being assessed a regulatory surcharge directly synthesizes two explicit passage facts: exclusive NMC farms failed to maintain continuous connectivity during peak hours, and failing continuous connectivity resulted in a regulatory surcharge. The statement regarding 2022 LFP-integrated farms directly applies the universal premise about LFP farms operating between 2018 and 2024.

Adım Adım Çözüm

1
Analyze the premise regarding NMC storage and regulatory surcharges.
No exclusive NMC farm maintained uninterrupted grid connectivity, and failing uninterrupted connectivity triggered a surcharge. Synthesizing these two premises proves that all exclusive NMC farms incurred surcharges.
Direct deduction from linked conditional premises.
2
Analyze the premise regarding LFP storage for farms built in 2022.
The year 2022 is within 2018–2024. All LFP farms in this period achieved continuous grid synchronization during peak demand hours.
Direct application of a general premise to a specific year within the defined timeframe.
3
Evaluate the incorrect choices for logical leaps or scope errors.
Statements introducing unmentioned metrics (total electricity generation), necessary/sufficient confusions (sole method), or formal conditional reversals are invalid inferences.
Valid inferences on the GMAT must be strictly supported without external assumptions or formal fallacies.
