Zorluk: ZorFlaw in the Reasoning

Hospital Administrator: A regional medical center cannot attain Tier-One trauma designation unless it maintains a board-certified trauma surgeon on site at all times and operates a dedicated blood transfusion unit. Valley General Hospital has just instituted continuous on-site staffing of board-certified trauma surgeons and completed the installation of a dedicated blood transfusion unit. It follows that Valley General will attain Tier-One trauma designation during its upcoming evaluation.

Which one of the following most accurately describes a flaw in the hospital administrator's reasoning?

  1. A
    infers that because two organizational reforms were completed simultaneously, one must be the direct cause of the other
  2. B
    bases its conclusion on an unstated assumption that the evaluating board has historically lowered its qualification standards
  3. treats a set of conditions that are necessary for attaining the designation as though they are sufficient to guarantee itCevap
  4. D
    rejects the criteria established by the accrediting board on the grounds that they are overly restrictive
  5. E
    relies on a premise that merely restates the final conclusion in different terms

Cevap

The argument treats conditions that are necessary for attaining the Tier-One trauma designation as though they are sufficient to guarantee that the designation will be awarded.
The administrator establishes that having on-site surgeons and a dedicated blood transfusion unit are mandatory minimum prerequisites for Tier-One designation. Meeting these necessary prerequisites does not establish that they are the only requirements needed for designation. By concluding that fulfilling these prerequisites guarantees designation, the argument mistakenly treats necessary conditions as sufficient.

Adım Adım Çözüm

1
Analyze the conditional relationship established in the first premise.
The phrase 'cannot attain... unless...' establishes that continuous on-site trauma surgeons and a dedicated blood transfusion unit are necessary conditions for Tier-One designation (Tier-One Designation → On-site Surgeons AND Transfusion Unit).
Accurately identifying conditional indicator words is essential for mapping the logical dependencies of the argument.
2
Evaluate the factual premise and the conclusion.
The premise establishes that Valley General satisfies both necessary conditions. The administrator concludes that Valley General will definitely achieve Tier-One designation.
This isolates the inferential gap between satisfying required prerequisites and guaranteeing the ultimate outcome.
3
Identify the reasoning error.
The author concludes that satisfying the necessary conditions guarantees the outcome (affirming the consequent / mistaking necessary for sufficient). Fulfilling minimum prerequisites does not ensure there are no additional requirements for designation.
A valid flaw description must precisely articulate this conditional error.
