Difficulty: HardApplying the Negation Technique

Archaeologist: The recently excavated clay tablets at the ancient city of Olaria contain administrative records of grain distribution written in the Kaelen dialect. Linguistic evidence confirms that Kaelen was predominantly spoken in the distant Vesper Mountains during the time Olaria was active. Therefore, the presence of these administrative records indicates that the Vesper Mountain civilization must have engaged in extensive commerce with Olaria.

Which of the following statements, if properly negated, would severely undermine the archaeologist's conclusion? Select all that apply.

  1. The Kaelen dialect was not forced upon the administrators of Olaria by a Vesper Mountain military occupation.Answer
  2. B
    Any civilization that integrates a foreign dialect into its administrative records must have engaged in extensive commerce with the region where that dialect originated.
  3. The presence of the Kaelen dialect in Olaria's records was not solely the result of a mass migration of Vesper Mountain refugees fleeing into Olaria.Answer
  4. D
    The Kaelen dialect was the only language capable of accurately recording complex grain distribution data during that historical period.
  5. E
    The volume of grain recorded in the clay tablets at Olaria was directly responsible for the economic growth of the Vesper Mountain civilization.

Answer

The statements that undermine the conclusion when negated are the ones ruling out military occupation and refugee migration as alternate causes for the language transfer.
The correct statements serve as 'Defender' assumptions. The archaeologist argues that the presence of a foreign dialect proves extensive commerce. This assumes there are no other viable ways the dialect could have become integrated into official records. By negating these statements, we introduce alternative mechanisms (military occupation and mass migration) for the language transfer. If either of these alternative mechanisms is true, the conclusion that commerce 'must have' occurred is completely destroyed.

Step-by-Step Solution

1
Identify the core argument (Premises and Conclusion).
Premises: Olaria's records use the Kaelen dialect; Kaelen was spoken in the Vesper Mountains. Conclusion: Olaria and Vesper Mountains MUST have engaged in extensive commerce.
Understanding the exact structural gap between the evidence and the conclusion is required before testing assumptions.
2
Analyze the logical gap (Flaw).
The author assumes that 'commerce' is the ONLY possible way a language could transfer from the Vesper Mountains to Olaria's administrative records.
Identifying the author's blind spots reveals the 'Defender' assumptions needed to protect the argument from alternative explanations.
3
Apply the Negation Technique to candidate statements.
Negating the correct statements introduces alternative causes (military conquest, refugee migration) for the language transfer, which destroys the 'must have been commerce' conclusion.
A necessary assumption is a statement that MUST be true for the conclusion to hold. If its logical opposite destroys the conclusion, the statement is indeed a necessary assumption.
