Zorluk: Çok zorNecessary Assumption

Economic Historian: Some scholars attribute the abrupt economic collapse of the Vaelorian empire to hyperinflation driven by the over-mining of krytium, the rare metal that served as their sole currency. This hypothesis is entirely untenable. Archaeological evidence confirms that krytium was notoriously difficult to extract using Vaelorian technology, meaning the total supply of available krytium could not have increased rapidly enough to trigger hyperinflation. Consequently, the Vaelorian economic collapse must have been precipitated by an external shock, such as a prolonged drought or foreign embargo, rather than by any internal monetary policy.

Which one of the following is an assumption required by the economic historian's argument?

  1. A
    An external shock, such as a prolonged drought or foreign embargo, is the only event capable of precipitating the abrupt economic collapse of a civilization.
  2. B
    If the overall supply of krytium had increased rapidly enough to trigger hyperinflation, the Vaelorian economic collapse would not have been precipitated by an external shock.
  3. The execution of any internal monetary policy capable of precipitating the Vaelorian economic collapse would have necessitated a rapid expansion of the krytium supply.Cevap
  4. D
    Any external shock severe enough to precipitate an economic collapse would not have simultaneously caused a decrease in the availability of krytium.
  5. E
    Civilizations that rely on a single rare metal as their sole currency are inherently more susceptible to external economic shocks than those with diversified monetary systems.

Cevap

The assumption that any destructive internal monetary policy would require a rapid expansion of the krytium supply.
The correct answer bridges the logical gap between the evidence and the conclusion. The economic historian provides evidence that one specific monetary phenomenon (hyperinflation via over-mining krytium) was physically impossible. From this single piece of evidence, the historian leaps to the conclusion that absolutely NO internal monetary policy could have caused the collapse, leaving an external shock as the only remaining explanation. This dramatic shift in scope requires assuming that no other internal monetary policies could have caused the collapse without a rapid expansion of krytium. If an internal policy could cause the collapse without rapidly expanding krytium, the entire conclusion falls apart.

Adım Adım Çözüm

1
Identify the main conclusion of the argument.
The Vaelorian economic collapse must have been precipitated by an external shock rather than by any internal monetary policy.
To determine what an argument assumes, you must first precisely define the final claim it is trying to prove.
2
Identify the primary premises supporting the conclusion.
Krytium was too difficult to extract for its supply to increase rapidly enough to trigger hyperinflation.
Assumptions serve as the unstated logical bridge between the explicitly stated premises and the main conclusion.
3
Analyze the logical gap between the premises and the conclusion.
The premise eliminates one specific internal monetary issue (hyperinflation via over-mining). However, the conclusion abruptly rules out ALL internal monetary policies.
Identifying the scope shift from a specific instance to a broad categorical claim reveals the exact missing link in the author's reasoning.
4
Formulate the necessary assumption and apply the Negation Test to the options.
The argument must assume that eliminating the specific issue (rapid krytium expansion) effectively eliminates the entire category (destructive internal monetary policies). The correct option states this directly.
The Negation Test confirms a necessary assumption: if negating the statement destroys the argument's validity, it is logically required.
