Assess the four argumentative excerpts below, each of which contains a distinct logical flaw. Which abstract description most accurately identifies the primary reasoning vulnerability in each argument? Match each flawed excerpt with its corresponding flaw description.
- Chief Medical Administrator: Every individual department within our regional healthcare network successfully operated under its allocated budget this fiscal year. Therefore, the regional healthcare network as an aggregate organization cannot have incurred any net budgetary deficit this year.Infers that an entire system or collective entity possesses a specific characteristic simply because each of its constituent parts possesses that characteristic.
- Marine Biologist: Humpback whales produce low-frequency feeding vocalizations only when a dense aggregation of prey fish is present within their acoustic range. Hydrophone arrays have confirmed that a dense aggregation of prey fish is currently present within the pod's acoustic range; consequently, the pod will definitely produce low-frequency feeding vocalizations.Treats a condition that is necessary for a specific outcome to occur as though it were sufficient to guarantee that outcome.
- Forensic Auditor: The opposing consultant argues that the electronic transaction logs were deliberately altered via an automated script. However, that consultant has received honoraria from financial competitors of the transaction processor. We must therefore conclude that the transaction logs were authentic.Rejects a substantive factual assertion solely by questioning the personal affiliations or financial incentives of the individual asserting it.
- Urban Microclimate Specialist: To mitigate extreme ambient temperatures in the central commercial district, the municipal board must either resurface all thoroughfares with high-albedo coatings or mandate vegetative green roofs across all commercial properties. Because commercial property groups have blocked the green roof mandate, the board must resurface all thoroughfares with high-albedo coatings.Presumes without justification that only two mutual courses of action are available when other plausible alternatives may exist.
Cevap
The argument regarding the regional healthcare network matches the description of inferring a whole possesses a characteristic of its parts; the humpback whale argument matches the description of treating a necessary condition as sufficient; the forensic audit argument matches the description of rejecting an assertion by targeting personal incentives; and the urban microclimate argument matches the description of assuming only two courses of action exist.
Each argument contains a distinct, classic reasoning error that aligns with exactly one abstract flaw description: the healthcare excerpt commits a part-to-whole error (composition); the whale vocalization excerpt commits a necessary/sufficient conditional error; the audit excerpt commits an ad hominem source dismissal; and the urban microclimate excerpt commits a false dilemma.
