Zorluk: OrtaIdentifying Underlying Assumptions

A historian studying medieval trade notes that during the mid-fourteenth century, merchants in several Mediterranean port cities rapidly shifted from single-entry accounting to complex double-entry bookkeeping. The historian concludes that this shift was caused primarily by the regional introduction of inexpensive rag-based paper, which made maintaining voluminous ledger books financially viable for average merchant houses. Which of the following statements represent necessary unstated assumptions upon which the historian's argument depends? Select all that apply.

  1. Prior to the mid-fourteenth century, the high cost of writing materials was a primary factor preventing merchant houses from adopting double-entry bookkeeping.Cevap
  2. Merchant houses in these port cities had not already been routinely maintaining double-entry accounts on alternative, non-durable media prior to the arrival of cheap paper.Cevap
  3. C
    Rag-based paper manufactured during the mid-fourteenth century was significantly more durable than traditional animal parchment.
  4. D
    The manufacturing techniques used to produce rag-based paper were developed entirely independently of foreign technological influences.
  5. E
    Double-entry bookkeeping provides greater accuracy for tracking complex commercial transactions than single-entry accounting.

Cevap

The argument relies on two necessary assumptions: that writing material expense was indeed a major obstacle to adopting double-entry bookkeeping prior to the mid-fourteenth century, and that merchants were not already using double-entry methods on alternative media such as wax tablets.
The conclusion asserts a direct causal link between cheap paper and the adoption of double-entry bookkeeping. Applying the Negation Test demonstrates that if writing material cost was not a primary barrier, or if merchants were already using double-entry bookkeeping on another medium, the arrival of cheap paper could not have been the primary cause of the accounting shift.

Adım Adım Çözüm

1
Deconstruct the argument structure.
Premise: Merchants rapidly adopted double-entry bookkeeping in the mid-fourteenth century, coinciding with the arrival of cheap rag-based paper. Conclusion: Cheap paper was the primary cause of this adoption by making extensive record-keeping affordable.
Identifying the explicit premise and conclusion is essential before testing unstated assumptions.
2
Apply the Negation Test to candidate assumptions.
Negating the statement regarding cost as a barrier reveals that if cost was never a barrier, cheap paper could not be the primary cause of adoption. Negating the statement regarding alternative media reveals that if merchants were already doing double-entry bookkeeping on wax tablets, cheap paper did not cause the shift to double-entry bookkeeping.
A statement is a necessary assumption if and only if its negation logically invalidates the author's conclusion.
3
Eliminate non-essential distractors.
Statements regarding paper durability, technological origin, and general utility of double-entry accounting do not invalidate the core causal claim when negated.
Non-essential strengthening factors, out-of-scope historical details, and general background facts are not strictly necessary assumptions.
