Zorluk: OrtaAvoiding Out-of-Scope and 'Could Be True' Inference Traps

In 2025, an independent logistics firm evaluated all 80 regional distribution centers operated by a retail enterprise. The firm's audit reported that every distribution center that implemented an automated sorting system reduced its order processing error rate by at least 30 percent relative to 2024. Furthermore, the report noted that every distribution center that reduced its order processing error rate by at least 30 percent in 2025 was located in the Western Region.

Which of the following can be properly inferred from the information above?

  1. A
    Every distribution center located in the Western Region implemented an automated sorting system in 2025.
  2. B
    Distribution centers that did not implement an automated sorting system failed to achieve any reduction in their order processing error rates in 2025.
  3. Every distribution center evaluated in 2025 that implemented an automated sorting system was located in the Western Region.Cevap
  4. D
    Automated sorting systems were the most cost-effective method for reducing order processing error rates among the retailer's distribution centers in 2025.
  5. E
    A majority of the retail enterprise's 80 regional distribution centers were located in the Western Region in 2025.

Cevap

Every distribution center evaluated in 2025 that implemented an automated sorting system was located in the Western Region.
The correct answer directly combines the two premises given in the stimulus via formal transitive deduction: implementing an automated sorting system guarantees an error reduction of at least 30 percent, and achieving that reduction guarantees location in the Western Region. Therefore, any facility with an automated sorting system must be located in the Western Region.

Adım Adım Çözüm

1
Analyze the formal logic premises provided in the stimulus.
Premise 1: Automated Sorting System →\rightarrow Error Reduction ≥30%\ge 30\%. Premise 2: Error Reduction ≥30%→\ge 30\% \rightarrow Western Region Location.
Mapping the premises using conditional logic establishes the formal relationships between the variables.
2
Apply the transitive property of conditional logic to combine the premises.
Automated Sorting System →\rightarrow Western Region Location.
Since statement A leads to statement B, and statement B leads to statement C, statement A must logically lead to statement C.
3
Evaluate the options to identify the choice that represents a strict hypothetical syllogism without introducing outside concepts.
The statement asserting that any evaluated facility implementing an automated sorting system was located in the Western Region directly expresses this deduction.
A valid inference on the GMAT Critical Reasoning section must be strictly proven by the premises without relying on unstated assumptions.
