Zorluk: OrtaParallel Conditional Logic

Stimulus Argument: If a coral reef is to fully recover from a severe bleaching event, it must be situated in a region with stable ocean temperatures. However, no reef can maintain stable ocean temperatures unless it is shielded from the primary equatorial currents. Thus, any coral reef that fully recovers from a severe bleaching event must be shielded from the primary equatorial currents.

Candidate Argument: If a newly published novel is to win the prestigious Sterling Prize, it must have sold over a million copies. Furthermore, a novel can sell over a million copies only if it has been adapted into a major motion picture. Therefore, any novel that has been adapted into a major motion picture will win the prestigious Sterling Prize.

Statement: The pattern of reasoning in the candidate argument is logically parallel to the pattern of reasoning in the stimulus argument.

Cevap: Cevap

Cevap

False. The arguments are not logically parallel because the stimulus argument is valid, while the candidate argument commits a formal logical flaw.
The statement is false because the two arguments possess fundamentally different logical structures regarding their conclusions. The stimulus presents a valid transitive deduction (A → B, B → C, therefore A → C). While the candidate argument shares the premise structure (X → Y, Y → Z), it draws a flawed conclusion (Z → X), representing an illegal reversal.

Adım Adım Çözüm

1
Translate the stimulus argument into formal conditional logic.
Premise 1: Fully Recover → Stable Temperatures. Premise 2: Stable Temperatures → Shielded ('no B unless C' translates to B → C). Conclusion: Fully Recover → Shielded.
To identify the exact structural template and establish that the stimulus utilizes a valid transitive chain (A → B, B → C, therefore A → C).
2
Translate the candidate argument into formal conditional logic.
Premise 1: Win Prize → Million Copies. Premise 2: Million Copies → Adapted ('Y only if Z' translates to Y → Z). Conclusion: Adapted → Win Prize.
To map the candidate's logical flow and prepare it for structural comparison against the stimulus.
3
Compare the logical structures of the two arguments.
The stimulus correctly deduces A → C from its premises. The candidate incorrectly deduces C → A from its premises, reversing the sufficient and necessary conditions.
An argument containing a logical flaw (illegal reversal) cannot be parallel to an argument that is logically valid.

Parallel Conditional Logic: Analyzing and matching the formal symbolic structure and validity of natural language arguments, paying careful attention to the directionality of conditional conclusions.
