Zorluk: OrtaNecessary vs. Sufficient Condition Flaws

Match each argument excerpt on the left with the abstract description of its logical flaw on the right.

  • City Planner: The downtown revitalization project will be approved only if the federal grant is secured. We just received notice that the federal grant has been secured in full. Therefore, the downtown revitalization project is guaranteed to be approved.Takes a prerequisite for achieving a desired goal to be a condition that by itself guarantees the achievement of that goal.
  • Meteorologist: An atmospheric pressure drop of more than ten millibars is enough to cause a severe thunderstorm. Since the atmospheric pressure in our region has remained completely stable this week, we will definitely not experience a severe thunderstorm.Concludes that an event will not happen simply because one set of circumstances sufficient to cause it has not occurred.
  • Manager: Whenever our software development team is given a flexible deadline, they successfully deliver a bug-free application. Therefore, the only way to ensure the team delivers a bug-free application is to provide them with a flexible deadline.Mistakenly assumes that a condition proven to be adequate for producing a certain result is the only way to produce that result.
  • Safety Inspector: Unless the chemical storage tanks are inspected monthly, the facility will face a hazardous leak. The facility's management has rigorously ensured that the tanks are inspected every single month. Hence, the facility will absolutely not face a hazardous leak.Assumes that because a specific precautionary measure is necessary to prevent an adverse event, taking that measure is sufficient to ensure the event does not occur.

Cevap

The City Planner matches the prerequisite flaw; the Meteorologist matches the absent sufficient cause flaw; the Manager matches the adequate condition flaw; and the Safety Inspector matches the precautionary measure flaw.
Each correct pair accurately identifies the specific directional error in conditional reasoning. The City Planner and Safety Inspector both treat necessary conditions as sufficient, but in distinct contexts (achieving a goal vs. preventing a disaster). The Manager and Meteorologist both treat sufficient conditions as necessary, but in distinct ways (claiming an adequate condition is the only way vs. inferring an event won't happen from the lack of a sufficient cause).

Adım Adım Çözüm

1
Analyze the City Planner's argument for conditional indicators.
The argument states 'only if' (identifying a necessary condition) and concludes a guarantee (treating it as a sufficient condition).
Identifying the directional error is required to match the argument to its abstract description.
2
Analyze the Meteorologist's argument for conditional indicators.
The argument states 'is enough' (identifying a sufficient condition) and concludes that its absence means the outcome will absolutely not occur.
This isolates the flaw of illicitly inferring the absence of a phenomenon from the lack of one sufficient cause.
3
Analyze the Manager's argument for conditional indicators.
The argument uses 'whenever' (identifying a sufficient condition) but concludes it is the 'only way' (treating it as a necessary condition).
This isolates the error of treating a condition proven to be adequate as a strict requirement.
4
Analyze the Safety Inspector's argument for conditional indicators.
The argument states 'unless' (identifying a necessary precaution) and concludes that meeting this precaution guarantees safety (treating it as a sufficient condition).
This isolates the specific flaw of treating a required precaution as a guaranteed prevention of an adverse event.
