Zorluk: OrtaBridging Gap (Supporter) Assumptions

Urban Historian: The city's waterfront warehouse district features a distinctive cast-iron architectural style that is no longer utilized in modern construction. Because it employs this obsolete style, the district serves as a tangible link to our region's industrial heritage. Therefore, the city council is obligated to pass legislation protecting the warehouse district from demolition.

Which one of the following is an assumption on which the urban historian's argument depends?

  1. A
    The waterfront warehouse district is the only remaining neighborhood in the city that features a cast-iron architectural style.
  2. B
    Any district that the city council is obligated to protect from demolition must serve as a tangible link to the region's industrial heritage.
  3. C
    If an architectural style is still utilized in modern construction, the city council is not obligated to pass legislation protecting districts that feature it.
  4. The city council is obligated to pass protective legislation for any district that serves as a tangible link to the region's industrial heritage.Cevap
  5. E
    Modern construction methods are generally incapable of adequately replicating the distinctive features of historical cast-iron architecture.

Cevap

The city council is obligated to pass protective legislation for any district that serves as a tangible link to the region's industrial heritage.
The argument's conclusion introduces a normative obligation ('obligated to pass legislation protecting') that does not appear anywhere in the premises. The premises only establish that the district 'serves as a tangible link to our region's industrial heritage.' To logically reach the conclusion, there must be a rule connecting this stated premise to the new normative obligation. The correct answer bridges this exact gap by stating that serving as a tangible link triggers the council's obligation to protect the district. If this statement is negated, the argument falls apart completely.

Adım Adım Çözüm

1
Identify the main conclusion of the argument.
The conclusion is: 'The city council is obligated to pass legislation protecting the warehouse district from demolition.'
Locating the conclusion isolates the specific claim that the premises must support.
2
Identify the premises supporting the conclusion.
Premise 1: The district has an obsolete cast-iron style. Premise 2: Because of this obsolete style, the district serves as a tangible link to industrial heritage.
Understanding the evidence shows exactly what information is available to prove the conclusion.
3
Locate the conceptual gap ('rogue element') between the premises and the conclusion.
The concept of being 'obligated to pass legislation protecting' appears only in the conclusion. The premises only establish that the district is a 'tangible link to industrial heritage.'
A valid logical argument cannot introduce entirely new concepts in the conclusion without a premise linking them to the evidence.
4
Formulate the necessary supporter assumption to bridge the gap.
If something serves as a tangible link to the region's industrial heritage, then the city council is obligated to pass legislation protecting it.
This conditional statement connects the end of the premise chain directly to the new claim in the conclusion, making the argument logically sound.
